Add Custom CSS to your Desktop App
We add a
todesktop class to the html element on each page of your app. You can use this to identify when your app is being run as a desktop app.If you want to hide an element on your desktop app you could do something like this:
app.css
index.html
.announcement {
background-color: hotpink;
/* other styles... */
}
html.todesktop .announcement {
display: none;
}
<body>
<div class="announcement">
You should download our desktop app!
</div>
<!-- rest of your app -->
</body>
You can also do the opposite and only show an element in your desktop app.
A common use-case is to show browser controls (back, forward, refresh) in your desktop app's user interface. Here's an example of how you could achieve this:
app.css
index.html
.back-button, .forward-button {
display: none;
}
html.todesktop .back-button,
html.todesktop .forward-button {
display: block;
}
<nav>
<a href="/">Home</a>
<a class="back-button" onclick="window.history.back()">←</a>
<a class="foward-button" onclick="window.history.forward()">→</a>
</nav>
You may wish to add styles that apply only on specific operating systems.
Class name | Platform (operating system) target |
.todesktop-platform-win32 | Windows |
.todesktop-platform-darwin | macOs |
.todesktop-platform-linux | Linux |
In the styles below we add a margin that will only apply on the Mac operating system.
html.todesktop-platform-darwin .header {
margin-top: 10px;
}
