What is the purpose of View>Page Style in Firefox?

Question

What is the purpose of this menu? Are there supposed to be more options than no style and basic page style? Can I add more Styles? Does this have a history?

Answer 1

It's the website that provides the stylesheets. Some websites provide a choice of stylesheets which can be toggled between using this menu. Here's the documentation which gives the following example:

<link href="default.css" rel="stylesheet" type="text/css" title="Default Style">
<link href="fancy.css" rel="alternate stylesheet" type="text/css" title="Fancy">
<link href="basic.css" rel="alternate stylesheet" type="text/css" title="Basic">
