<![CDATA[Customizing UI with css]]>Hello again.

In Firefox we can easily change the UI with css, precisely with the userChrome.css file. I tried hard to find something similar for Opera and failed.

Some guidelines are for opera 12, some suggest using an extension, although don't mention which.

I for example want to make items in my bookmarks bar much smaller, including smaller space between them.

I really hope it's possible with just a css file, because this is one of two reasons I like Firefox 🙂
