This page details how to implement a Firefox OS 2.3
<gaia-header> web component in your own app.
First of all, make sure you have followed the preliminary setup instructions. Next,
cd into the directory containing your web app. You can install the
bower install gaia-components/gaia-header
The command installs not only the
gaia-header component, but also the base
gaia-component code that all gaia components need to run, plus the Gaia icons set that many Gaia web components make use of.
The following gives you an idea of what a rendered
gaia-header would look like:
Note: Remember that you need to be using a browser that supports web components (see the preliminary setup instructions for details.)
This section details all the code you need.
To include all of the styles and script that these components make use of, you need to add the following to your document head:
<script src="bower_components/gaia-icons/gaia-icons.js"></script> <link rel="stylesheet" type="text/css" href="bower_components/gaia-icons/gaia-icons.css"></link> <script src="bower_components/gaia-component/gaia-component.js"></script> <script src="bower_components/gaia-header/gaia-header.js"></script>
With the above setup done, you can now use a
<gaia-header> element anywhere you like:
<gaia-header action="back"> <h1>Keyboard Settings</h1> </gaia-header>
All you need to do is include the heading text you want inside the
<h1> element, and the type of action you want performed inside the
action attribute to include the correct icon. The available types are:
back: include a back button arrow icon.
menu: include a hamburger menu icon.
close: include a closing 'X'.
Note: If you don't want to include any kind of button in your header, simply remove the
You can also include custom buttons, links and other content inside your header by including it inside the
<gaia-header> element. For example:
<gaia-header action="menu"> <h1>Keyboard Settings</h1> <a data-icon="compose"></a> <button data-icon="more"></button> </gaia-header>
If choosing to use the built in action-button you may wish to localize the content within. You can do this by providing a specicial
.l10n-action child node.
<gaia-header action="back"> <span class="l10n-action" aria-label="Back">Localized text</span> <h1>title</h1> </gaia-header>
