HTMLMetaElement: media property
The HTMLMetaElement.media
property enables specifying the media for theme-color
metadata.
The theme-color
property enables setting the color of the browser's toolbar or UI in browsers and operating systems that support this property.
The media
property enables setting different theme colors for different media
values.
Value
A string.
Examples
Setting the theme color for dark mode
The following example creates a new <meta>
element with a name
attribute set to theme-color
.
The content
attribute is set to #3c790a
, the media
attribute is set to prefers-color-scheme: dark
, and the element is appended to the document <head>
.
When a user has specified a dark mode in their operating system, the media
property can be used to set a different theme-color
:
js
var meta = document.createElement("meta");
meta.name = "theme-color";
meta.content = "#3c790a";
meta.media = "(prefers-color-scheme: dark)";
document.head.appendChild(meta);
Setting theme colors by device size
Most meta properties can be used only once. However, theme-color
can be used multiple times if unique media
values are provided.
This example adds two meta elements with a theme-color
; one for all devices and another for small screens.
The order of matching the media
query matters, so the more specific query should be added later in the document, as shown below:
js
// Add a theme-color for all devices
meta = document.createElement("meta");
meta.name = "theme-color";
meta.content = "#ffffff";
document.head.appendChild(meta);
// Add a theme-color for small devices
var meta = document.createElement("meta");
meta.name = "theme-color";
meta.media = "(max-width: 600px)";
meta.content = "#000000";
document.head.appendChild(meta);
