Re: URL CSS pseudo class

I do not believe I am mistaken. While the technique you mention might  
work in a limited sense, it assumes that you then create a style for  
all possible URLs rather than a single style for the currently  
displayed URL. The current pseudo class could be applied without  
having to specify the URL. In the case of what Charles-André is  
suggestion, I'm wondering if we might want to consider something where  
if a specific URL is the current URL displayed in the agent, then a  
particular style is applied.

The disconnect with what you are saying versus what I am saying is  
whether the style sheet knows the current URL of the page or not.
