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:

        .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:

        .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>

Platform-specific CSS

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;
}
