So now that I've got this wonderful extension, URIid (and am looking forward to the day that we have @ rules for matching on URLs integrated into Gecko,) I'm doing a lot of customization of the sites I visit regularly.
I don't think I've ever really tried to learn CSS except by experimentation with the specs when I wanted to achieve a specific look here at my weblog or in tracking down a Mozilla bug. What I'm looking for now is a tutorial or other hand-holding document which will give me a better grip on using CSS. I'm not looking for links to the specs. I already have bookmarks to all of the w3c CSS specs.
What I'm really looking for is a guide that will teach me the most efficient ways to select a bit of random web content and modify its display. An example of the type of questions that I need answered woudld be something like "how do I select on and modify HTML table padding and cell spacing attributes using CSS?"
So, do any of you know of any tutorials or other documentation for the practical modification of other peoples' web pages with user style sheets?
