Can I apply a style to all website with stylish?

Question

I am using the add-on stylish in Firefox 8.0. I particularly like a plain style and I want to apply to all website. Can I do that? I tried *.com and it doesn't work.

You can apply a style to all websites by using the XHTML namespace:

@namespace url(http://www.w3.org/1999/xhtml);

Your CSS here.

Alternatively, to only modify the Firefox UI, you would use the XUL namespace:

@namespace url(http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul);

So, if you do not include a namespace, Stylish will modify all elements in Firefox.
