I've been travelling around Vanilla and I have a question: Is there a simple way to change some CSS style properties (e.g background color) of the first post of a thread?
I looked into the CSS file and seems that there's no specific style class for the first post.
Did anyone look in the HTML source? The class is there but just not used in the CSS, just use FirstComment as the class but make sure you define it after the comment class as the div has those both defined.
I'm no guru on CSS either, I didn't know about the specifying multiple class thing until I saw Mark's code, in some quick tests I did though (with Konqueror) any changes didn't take effect until I placed the FirstComment at the end of the CSS assumedly because the style had already been defined with the comment class.
There are some styles that are position sensitive, pet example are the 'a:styles' a:hover, a:visited and so on, they are pretty sensitive on which order you put them in.
If there is a already definitive style for a series of things, the style that will define a one part of the definitive style (i.e. body defines ALL text, but you can change parts of text with Div) will have to come after it.
I haven't had the time to check out the CSS makings of Vanilla, but if I had I'd surely would be able to give you more specified answer.
