About alternative style sheets

Firefox offers support for alternative style sheets. Pages that provide alternative style sheets allow the user to select the style in which the page is displayed using the View>Page Style submenu. This provides a way for users to see multiple versions of a page, based on their needs or preferences.

A web page can use the <link> element to add alternative style sheets to a document.

Try it out!

Go to the View>Page Style submenu and select a different style to watch this page's look change!
