-moz-windows-accent-color-in-titlebar

Non-standard
This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

Note: Since Firefox 58, this media feature is no longer available to web content — it is only available internally (e.g. to XUL / chrome code). See bug 1396066 for more details.

The -moz-windows-accent-color-in-titlebar Gecko-only CSS media feature can be used to apply styles based on whether accent colors are enabled in Microsoft Windows titlebars.

Syntax

<integer>
In recent Windows versions (e.g., 10), if accent colors are enabled in window titlebars, this is 1. Otherwise it's 0.

Media: media/visual
Accepts min/max prefixes: no

Example

@media (-moz-windows-accent-color-in-titlebar: 1) {
  h1 {
    color: -moz-win-accentcolortext;
  }

  body {
    background-color: -moz-win-accentcolor;
  }
}

  • This feature is closely related to the Mozilla-specific <color> values -moz-win-accentcolor and -moz-win-accentcolortext, which allow you to access the Windows accent and overlaid text accent colors from CSS.
