7.css is a CSS framework for building interface components that look like Windows 7. It is built on top of the GUI backbone of XP.css, which is an extension of 98.css.
Hello, world!
This framework relies on the usage of semantic HTML. To make a button, you'll need
to use a <button>. Input elements require labels. Tabs rely on the role="tab"
attribute.
This page will guide you through that process, but accessibility is a primary goal of this project.
You can override many of the styles of your elements while maintaining the appearance provided by this framework. Need more padding on your buttons? Go for it. Need to add some color to your input labels? Be our guest.
This framework does not contain any JavaScript, it merely styles your HTML with some CSS. This means 7.css is compatible with your frontend framework of choice.
The fastest way to use 7.css is to import it from unpkg.
<link rel="stylesheet" href="https://unpkg.com/7.css">
You can also install 7.css from npm.
Installation
npm install 7.css
Usage
import "7.css/dist/7.css";
In case you need 7.css to coexist with another CSS/styling framework, you may use the 7.scoped.css
stylesheet instead to scope the styling within a win7 class.
unpkg:
https://unpkg.com/7.css/dist/7.scoped.css
or npm:
import "7.css/dist/7.scoped.css"
Then in your code, wrap the component with .win7:
<div class="win7">
<button>A Win7-styled button</button>
</div>Also note that using the scoped stylesheet will eliminate the scrollbar styling as well.
In case you only need the styling of certain components rather than the complete stylesheet as a whole, you may import them separately as below:
unpkg:
https://unpkg.com/7.css/dist/gui/buttons.css https://unpkg.com/7.css/dist/gui/tabs.css
or npm:
import "7.css/dist/gui/buttons.css" import "7.css/dist/gui/tabs.css"
For more components, see the published gui folder.
A balloon is a small pop-up window that informs users of a non-critical problem or special condition in a control.
A balloon or tooltip can be created using the role="tooltip" attribute.
<div role="tooltip">A balloon is better known as tooltip in web development.</div>
A control may bind to a balloon with the aria-describedby attribute.
You will need to set up an event for the control to trigger the balloon.
<input type="text" placeholder="Press Enter" aria-describedby="balloon-password" />
<div role="tooltip" id="balloon-password" hidden>Press Backspace to dismiss</div>To change the position of the balloon, which subsequently change the placement of its tail, combine the respective vertical and horizontal classes:
.is-top / .is-bottom.is-left / .is-right<div role="tooltip">This balloon is positioned bottom right of the source control (default behavior).</div>
<div role="tooltip" class="is-bottom is-left">This balloon is positioned bottom left of the source control.</div>
<div role="tooltip" class="is-top is-left">This balloon is positioned top left of the source control.</div>
<div role="tooltip" class="is-top is-right">This balloon is positioned top right of the source control.</div>A command button, also referred to as a push button, is a control that causes the application to perform some action when the user clicks it.
A standard button measures 75px wide and 23px tall with 12px of horizontal padding by default. They are styled with 2 shades of gray as a vertical gradient.
<button>Click me</button>When buttons are clicked, the gray gradient is shifted to corresponding sky blues. The following button is simulated to be in the pressed (active) state.
<button>I am being pressed</button>Disabled buttons have solid background and lighter border.
<button disabled>I cannot be clicked</button>Button focus is communicated with a dotted border, set 4px within the contents of the button. The following example is simulated to be focused.
<button>I am focused</button>A default button (in Windows, hitting the Enter key in a dialog context triggers the button) has a greenish-blue border and a light blue gradient shade.
<button class="default">I am the one!</button>A check box represents an independent or non-exclusive choice.
Checkboxes are represented with a sunken panel, populated with a "check" icon when selected, next to a label indicating the choice.
Note: You must include a corresponding label after
your checkbox, using the <label> element with a for attribute
pointed at the id of your input. This ensures the checkbox is easy to use with
assistive technologies, on top of ensuring a good user experience for all (navigating with the tab key,
being able to click the entire label to select the box).
<input type="checkbox" id="example1">
<label for="example1">This is a checkbox</label>
Checkboxes can be selected and disabled with the standard checked and disabled
attributes.
When grouping inputs, wrap each input in a container with the field-row class. This ensures
a consistent spacing between inputs.
<div class="field-row">
<input checked type="checkbox" id="example2">
<label for="example2">I am checked</label>
</div>
<div class="field-row">
<input disabled type="checkbox" id="example3">
<label for="example3">I am inactive</label>
</div>
<div class="field-row">
<input checked disabled type="checkbox" id="example4">
<label for="example4">I am inactive but still checked</label>
</div>Users can show or hide additional information including data, options, or commands.
A collapsible section can be created using the elements details and
summary.
🎉 Tadah!
<details>
<summary>Expand me to see something interesting</summary>
<p>🎉 Tadah!</p>
</details>Add an open attribute to expand the content by default.
<details open>
<summary>I open myself willingly</summary>
<ul>
<li>This is my family</li>
<li>This is my house</li>
<li>This is my car</li>
</ul>
</details>A combo box is a combination of a standard list box or a drop-down list and an editable text box, thus allowing users to enter a value that isn't in the list.
To render a combo box, use a text input, a button,
a parent ul, and children li together,
wrapped inside a container element with the combobox class.
For accessibility, follow the minimum requirements as below:
role="combobox" attribute to the text inputrole="listbox" attribute to the ulrole="option" attribute to each liid of the listbox with the aria-owns attribute
on the text input
<div class="combobox">
<input type="text" role="combobox" aria-owns="company" />
<button></button>
<ul role="listbox" id="company">
<li role="option">Facebook</li>
<li role="option">Amazon</li>
<li role="option">Apple</li>
<li role="option">Netflix</li>
<li role="option">Google</li>
</ul>
</div>For more options of the list box, see the ListBox section.
A drop-down list box allows the selection of only a single item from a list. In its closed state, the control displays the current value for the control. The user opens the list to change the value.
Dropdowns can be rendered by using the select and option
elements.
<select>
<option>5 - Incredible!</option>
<option>4 - Great!</option>
<option>3 - Pretty good</option>
<option>2 - Not so great</option>
<option>1 - Unfortunate</option>
</select>
By default, the first option will be selected. You can change this by
giving one of your option elements the selected
attribute.
<select>
<option>5 - Incredible!</option>
<option>4 - Great!</option>
<option selected>3 - Pretty good</option>
<option>2 - Not so great</option>
<option>1 - Unfortunate</option>
</select>A group box is a special control you can use to organize a set of controls. A group box is a rectangular frame with an optional label that surrounds a set of controls.
A group box can be used by wrapping your elements with the fieldset tag.
It contains a sunken outer border and a raised inner border, resembling an engraved box
around your controls.
<fieldset>
<div class="field-row">Select one:</div>
<div class="field-row">
<input id="radio5" type="radio" name="fieldset-example">
<label for="radio5">Diners</label>
</div>
<div class="field-row">
<input id="radio6" type="radio" name="fieldset-example">
<label for="radio6">Drive-Ins</label>
</div>
<div class="field-row">
<input id="radio7" type="radio" name="fieldset-example">
<label for="radio7">Dives</label>
</div>
</fieldset>
You can provide your group with a label by placing a legend element
within the fieldset.
<fieldset>
<legend>Today's mood</legend>
<div class="field-row">
<input id="radio8" type="radio" name="fieldset-example2">
<label for="radio8">Claire Saffitz</label>
</div>
<div class="field-row">
<input id="radio9" type="radio" name="fieldset-example2">
<label for="radio9">Brad Leone</label>
</div>
<div class="field-row">
<input id="radio10" type="radio" name="fieldset-example2">
<label for="radio10">Chris Morocco</label>
</div>
<div class="field-row">
<input id="radio11" type="radio" name="fieldset-example2">
<label for="radio11">Carla Lalli Music</label>
</div>
</fieldset>With a list box, users can select from a set of values presented in a list that is always visible.
There are 2 ways you can render a list box. The simple one is using the select
element with a multiple attribute specified.
<select multiple>
<option>5 - Incredible!</option>
<option selected>4 - Great!</option>
<option>3 - Pretty good</option>
<option>2 - Not so great</option>
<option>1 - Unfortunate</option>
</select>
The complex one is using a combination of the ul/li elements
with the role attributes.
<ul role="listbox">
<li role="option">Facebook</li>
<li role="option" aria-selected="true">Amazon</li>
<li role="option">Apple</li>
<li role="option">Netflix</li>
<li role="option">Google</li>
</ul>
The latter offers more flexibility over using a mere select element.
Choose the one that is more appropriate depending on your context or use case.
To add a drop shadow to the list box, use the has-shadow class.
To add a hovering style on the list box items (using role attribute only),
use the has-hover class.
<ul role="listbox" class="has-shadow has-hover">
<li role="option">Facebook</li>
<li role="option">Amazon</li>
<li role="option">Apple</li>
<li role="option">Netflix</li>
<li role="option">Google</li>
</ul>The following components compose a complete navigation menu, also known as Navbar.
Menus are hierarchical lists of commands or options available to users in the current context.
A menu can be rendered using a composition of a parent ul and child items
li, role="menu" and role="menuitem" attributes
must be specified on the ul and li respectively.
If a menu item has a submenu, add an aria-haspopup="true" attribute to it
to render a caret indicator.
To make the menu focusable, specify the tabindex attributes on the items.
Alternatively, you can use an a to achieve the same.
<ul role="menu" style="width: 200px">
<li role="menuitem" tabindex="0" aria-haspopup="true">View</li>
<li role="menuitem" tabindex="0" aria-haspopup="true">
Sort by
<ul role="menu">
<li role="menuitem"><a href="#menu">Name</a></li>
<li role="menuitem"><a href="#menu">Size</a></li>
<li role="menuitem"><a href="#menu">Item type</a></li>
<li role="menuitem"><a href="#menu">Date modified</a></li>
</ul>
</li>
<li role="menuitem"><a href="#menu">Refresh</a></li>
<li role="menuitem"><a href="#menu">Paste</a></li>
<li role="menuitem"><a href="#menu">Paste shortcut</a></li>
<li role="menuitem"><a href="#menu">Screen resolution</a></li>
<li role="menuitem"><a href="#menu">Gadgets</a></li>
<li role="menuitem"><a href="#menu">Personalize</a></li>
</ul>
By default, the submenu is only shown when the linked item is focused/clicked.
To add the hovering/mouse-over trigger, you can add a can-hover
class to the root container.
Use a has-divider class to make a horizontal line after the menu item.
Disable a menu item by placing an aria-disabled attribute on it.
You may associate a menu item with an icon by using the img element.
(Icons provided by Icons8)
<ul role="menu" class="can-hover" style="width: 200px">
<li role="menuitem" tabindex="0" aria-haspopup="true">View</li>
<li role="menuitem" tabindex="0" aria-haspopup="true">
Sort by
<ul role="menu">
<li role="menuitem"><a href="#menu">Name</a></li>
<li role="menuitem"><a href="#menu">Size</a></li>
<li role="menuitem"><a href="#menu">Item type</a></li>
<li role="menuitem"><a href="#menu">Date modified</a></li>
</ul>
</li>
<li role="menuitem" class="has-divider"><a href="#menu">Refresh</a></li>
<li role="menuitem" aria-disabled="true"><a href="#menu">Paste</a></li>
<li role="menuitem" aria-disabled="true" class="has-divider">
<a href="#menu">Paste shortcut</a>
</li>
<li role="menuitem">
<img src="https://img.icons8.com/color/18/000000/monitor--v1.png"/>
<a href="#menu">Screen resolution</a>
</li>
<li role="menuitem">
<img src="https://img.icons8.com/color/18/000000/virtual-machine2.png"/>
<a href="#menu">Gadgets</a>
</li>
<li role="menuitem">
<img src="https://img.icons8.com/color/18/000000/remote-desktop.png"/>
<a href="#menu">Personalize</a>
</li>
</ul>
To render menu items that are options with bullets and checkmarks, use the corresponding
input type (radio or checkbox).
<ul role="menu" style="width: 200px">
<li role="menuitem">
<input type="radio" name="icon-size" id="example12">
<label for="example12">Large icons</label>
</li>
<li role="menuitem">
<input type="radio" name="icon-size" id="example13" checked>
<label for="example13">Medium icons</label>
</li>
<li role="menuitem" class="has-divider">
<input type="radio" name="icon-size" id="example14">
<label for="example14">Small icons</label>
</li>
<li role="menuitem">
<input type="checkbox" id="example15">
<label for="example15">Auto arrange icons</label>
</li>
<li role="menuitem">
<input type="checkbox" id="example16" checked>
<label for="example16">Align icons to grid</label>
</li>
</ul>A menu bar is a list of labeled menu categories typically located near the top of a window.
A menu bar can be created in a similar manner to the menu, however, use a
role="menubar" attribute in place of role="menu".
<ul role="menubar">
<li role="menuitem" tabindex="0">File</li>
<li role="menuitem" tabindex="0">Edit</li>
<li role="menuitem" tabindex="0">View</li>
<li role="menuitem" tabindex="0">Help</li>
</ul>Combining it with the Menu component, we will have a complete menu bar with the associated menu dropdowns.
To accommodate an extra piece of info for a menu item (like a shortcut mnemonic)
on the right side, nest it with an span element.
<ul role="menubar" class="can-hover">
<li role="menuitem" tabindex="0" aria-haspopup="true">
File
<ul role="menu">
<li role="menuitem">
<a href="#menubar">
Open <span>Ctrl+O</span>
</a>
</li>
<li role="menuitem">
<a href="#menubar">
Save <span>Ctrl+S</span>
</a>
</li>
<li role="menuitem" class="has-divider">
<a href="#menubar">
Save As... <span>Ctrl+Shift+S</span>
</a>
</li>
<li role="menuitem"><a href="#menubar">Exit</a></li>
</ul>
</li>
<li role="menuitem" tabindex="0" aria-haspopup="true">

<ul role="menu">
<li role="menuitem"><a href="#menubar">Undo</a></li>

<li role="menuitem"><a href="#menubar">Replace...</a></li>
<li role="menuitem"><a href="#menubar">Go to...</a></li>
</ul>
</li>
<li role="menuitem" tabindex="0" aria-haspopup="true">

<ul role="menu">
<li role="menuitem" tabindex="0" aria-haspopup="true">
Zoom
<ul role="menu">
<li role="menuitem"><button>Zoom In</button></li>
<li role="menuitem"><button>Zoom Out</button></li>
</ul>

<li role="menuitem" tabindex="0" aria-haspopup="true">

<ul role="menu">
<li role="menuitem"><a href="#menubar">View Help</a></li>
<li role="menuitem"><a href="#menubar">About</a></li>
</ul>
</li>
</ul>An option button, also referred to as a radio button, represents a single choice within a limited set of mutually exclusive choices. That is, the user can choose only one set of options.
Option buttons can be used via the radio type on an input element.
Option buttons can be grouped by specifying a shared name attribute on each
input. Just as before: when grouping inputs, wrap each input in a container with the
field-row class to ensure a consistent spacing between inputs.
<div class="field-row">
<input id="radio17" type="radio" name="first-example">
<label for="radio17">Yes</label>
</div>
<div class="field-row">
<input id="radio18" type="radio" name="first-example">
<label for="radio18">No</label>
</div>
Option buttons can also be checked and disabled with their corresponding
HTML attributes.
<div class="field-row">
<input id="radio19" type="radio" name="second-example">
<label for="radio19">Peanut butter should be smooth</label>
</div>
<div class="field-row">
<input checked disabled id="radio20" type="radio" name="second-example">
<label for="radio20">I understand why people like crunchy peanut butter</label>
</div>
<div class="field-row">
<input disabled id="radio21" type="radio" name="second-example">
<label for="radio21">Crunchy peanut butter is good</label>
</div>A common control that displays the progress of a particular operation as a graphical bar.
Progress bars can be created with a div using role="progressbar",
and another nested div is required to make the inner bar.
Specify the width of the inner bar to indicate the progress.
For accessibility, you might want to specify the respective aria-* attributes.
Refer to MDN
for more information.
<div role="progressbar" aria-valuemin="0" aria-valuemax="100" aria-valuenow="80">
<div style="width: 80%"></div>
</div>
To indicate the progress bar in paused state, add a paused class.
<div role="progressbar" class="paused">
<div style="width: 50%"></div>
</div>
To indicate the progress bar in error state, add an error class.
<div role="progressbar" class="error">
<div style="width: 30%"></div>
</div>
To animate the progress bar, add an animate class.
<div role="progressbar" class="animate">
<div style="width: 60%"></div>
</div>
To create an indeterminate progress bar, add a marquee class
and remove the nested div.
<div role="progressbar" class="marquee"></div>A control that allows users to scroll the content of a window, either vertically or horizontally.
To override the browser scrollbar's system styling for a particular section, add a has-scrollbar
class to the container element.
Note that this only works with WebKit-based browsers.
<div class="has-scrollbar" style="width: 300px; height: 150px; overflow: auto">

</div>With a Search box, users can quickly locate specific objects or text within a large set of data by filtering or highlighting matches.
There are 2 variants of the search box available.
An instant search, where the results are displayed immediately as the user types, can be rendered
just by specifying a type="search" attribute on an input element:
<input type="search" placeholder="Search" />
A regular search, where a search is performed when the user clicks the search button, requires
a search input and a button wrapped inside a container a container element with the class searchbox.
<div class="searchbox">
<input type="search" placeholder="Search" />
<button aria-label="search"></button>
</div>A slider, sometimes called a trackbar control, consists of a bar that defines the extent or range of the adjustment and an indicator that shows the current value for the control...
Sliders can rendered by specifying a range type on an
input element.
<div class="field-row" style="max-width: 300px">
<label>Volume:</label>
<label>Low</label>
<input type="range" min="1" max="11" value="5" />
<label>High</label>
</div>
You can make use of the has-box-indicator class replace the
default indicator with a box indicator, furthermore the slider can be wrapped
with a div using is-vertical to display the input vertically.
Note: To change the length of a vertical slider, the input width
and div height.
<div class="field-row">
<label>Cowbell</label>
<div class="is-vertical">
<input class="has-box-indicator" type="range" min="1" max="3" step="1" value="2" />
</div>
</div>A spinner or loader, also referred as ProgressRing, is a type of progress control to indicate that an operation is underway and its completion time is unknown.
To render a spinner element, use either a spinner or a loader
class. To animate the spinner, add an animate class.
For accessibility, we use an aria-label attribute with a desired text
to inform assistive technologies about the presence of the spinner.
<span class="spinner" aria-label="Spinning"></span>
<span class="loader" aria-label="Loading"></span>
<span class="loader animate" aria-label="Processing your request"></span>Tabs provide a way to present related information on separate labeled pages.
To create a tab, use a menu element with role="tablist".
Then for the tab titles, use a button with role="tab", and set the aria-controls attribute to
the corresponding id of the element with role="tabpanel".

</section>A text box (also referred to as an edit control) is a rectangular control where the user enters or edits text. It can be defined to support a single line or multiple lines of text.
Text boxes can rendered by specifying a text type on an
input element. As with checkboxes and radio buttons, you
should provide a corresponding label with a properly set for
attribute, and wrap both in a container with the field-row class.
<div class="field-row">
<label for="text26">Occupation</label>
<input id="text26" type="text" />
</div>
Additionally, you can make use of the field-row-stacked class
to position your label above the input instead of beside it.
<div class="field-row-stacked" style="width: 200px">
<label for="text27">Address (Line 1)</label>
<input id="text27" type="text" />
</div>
<div class="field-row-stacked" style="width: 200px">
<label for="text28">Address (Line 2)</label>
<input id="text28" type="text" />
</div>
To support multiple lines in the user's input, use the textarea
element instead.
<div class="field-row-stacked" style="width: 200px">

</div>A tree view control is a special list box control that displays a set of objects as an indented outline based on their logical hierarchical relationship.
To render a tree view, use an ul element with the
tree-view class. The children of this list (li
elements), can contain whatever you'd like.
<ul class="tree-view has-container">
<li>We can put</li>
<li><strong style="color: purple">✨ Whatever ✨</strong></li>
<li>We want in here</li>
</ul>
To make this a tree, we can nest further ul elements
(no class needed on these). This will provide them with indentation
to illustrate the hierarchical relations of the tree.
To create collapsible sections, wrap child lists inside details elements.
<ul class="tree-view has-container">

The has-connector class may be used to render a dotted border to illustrate
the structure more clearly, and the has-collapse-button class to change
the expand/collapse carets to buttons.

</ul>The following components illustrate how to build complete windows using 7.css.
At the top edge of the window, inside its border, is the title bar (also reffered to as the caption or caption bar), which extends across the width of the window. The title bar identifies the contents of the window.
Include command buttons associated with the common commands of the primary window in the title bar. These buttons act as shortcuts to specific window commands.
You can build a complete title bar by making use of three classes,
title-bar, title-bar-text, and title-bar-controls.
<div class="title-bar">
<div class="title-bar-text">A Title Bar</div>
<div class="title-bar-controls">
<button aria-label="Close"></button>
</div>
</div>
We make use of aria-label to render the Close button, to let
assistive technologies know the intent of this button. You may also use
"Minimize" and "Maximize" like so:
<div class="title-bar">
<div class="title-bar-text">A Title Bar</div>
<div class="title-bar-controls">
<button aria-label="Minimize"></button>
<button aria-label="Maximize"></button>
<button aria-label="Close"></button>
</div>
</div>
<br>
<div class="title-bar">
<div class="title-bar-text">A maximized Title Bar</div>
<div class="title-bar-controls">
<button aria-label="Minimize"></button>
<button aria-label="Restore"></button>
<button aria-label="Close"></button>
</div>
</div>
Alternatively, you can use the is-close, is-minimize,
is-maximize, is-restore classes to target the respective
controls for your styling preference.
To give our title bar a home, we wrap it in a window container.
This provides a drop shadow to it. We can freely resize the window by specifying
a width in the container style.
<div class="window" style="max-width: 300px">
<div class="title-bar">
<div class="title-bar-text">A complete window</div>
<div class="title-bar-controls">
<button aria-label="Minimize"></button>
<button aria-label="Maximize"></button>
<button aria-label="Close"></button>
</div>
</div>
</div>
Place an active class either on the window container or
the title bar itself to enable the active styles for the controls.
<div class="window active" style="max-width: 300px">
<div class="title-bar">
<div class="title-bar-text">A complete window</div>
<div class="title-bar-controls">
<button aria-label="Minimize"></button>
<button aria-label="Maximize" disabled></button>
<button aria-label="Close"></button>
</div>
</div>
</div>Every window has a boundary that defines its shape.
To draw the contents of the window, we use the window-body
class under the title bar. You may use the has-space class to add some padding
to the window body.
There's so much room for activities!
<div class="window active" style="max-width: 300px">
<div class="title-bar">
<div class="title-bar-text">A window with contents</div>
<div class="title-bar-controls">
<button aria-label="Minimize"></button>
<button aria-label="Maximize"></button>
<button aria-label="Close"></button>
</div>
</div>
<div class="window-body has-space">
<p>There's so much room for activities!</p>
</div>

You create the content for each tab by using an article tag.
<div class="window active" style="max-width: 400px">
<div class="title-bar">
<div class="title-bar-text">Another window with contents</div>
<div class="title-bar-controls">

</div>A status bar is a special area within a window, typically the bottom, that displays information about the current state of what is being viewed in the window or any other contextual information, such as keyboard state.
You can render a status bar with the status-bar class,
and status-bar-field for every child text element.
There are just so many possibilities:
<div class="window" style="max-width: 320px">
<div class="title-bar">
<div class="title-bar-text">A Window With A Status Bar</div>
</div>
<div class="window-body has-space">

<li>Or even a File Explorer!</li>

</div>
</div>The glass window frames are a striking new aspect of the Microsoft Windows aesthetic, aiming to be both attractive and lightweight. These translucent frames give windows an open, less intrusive appearance, helping users focus on content and functionality rather than the interface surrounding it.
You can produce this "striking aspect" of the window with a glass class.
The window frame then becomes translucent, the background is blurred behind the window.
The background behind is blurred.
<div class="background">
<div class="window glass active" style="max-width: 100%">
<div class="title-bar">
<div class="title-bar-text">A glass window frame</div>
<div class="title-bar-controls">

<button aria-label="Close"></button>
</div>
</div>
<div class="window-body has-space">
<p>The background behind is blurred.</p>
</div>
</div>
</div>
If you want to override the default color of the window, you can specify the
background-color attribute in the before pseudo element
and the title-bar under the same parent class as window.
You can change the window color just as simple.
And even the glass window frame as well.
<style>
.violet::before,
.violet > .title-bar {

</div>A dialog box is a secondary window that allows users to perform a command, asks users a question, or provides users with information or progress feedback.
Without JavaScript, a dialog box can be triggered by utilizing the URL fragment of an a element
(denoted by the # sign), targeting a corresponding dialog box element with the matching id.
For accessibility, define the role="dialog" attribute on the element.
Additionally, label the dialog using the aria-labelledby attribute, with the value
pointing to the id of the title bar's text element.
<a href="#dialog-demo">Open Dialog</a>
<div class="window active is-bright" id="dialog-demo" role="dialog" aria-labelledby="dialog-title">
