I wanted to share this new discovery (api.jquery.com) and also mention some other great online web development resources that I use on a regular basis.
Mozilla Developer Center
Color Scheme Designer
I have used this tool for a long time. I am more of a programmer than a graphic designer, so it is not that easy for me to pick out great color combinations, which is where this application comes in. You can save schemes that you design by saving a link to the specific scheme (here is a scheme I like).
I have used the reference that they have for years because it quickly shows me the tags or properties that I am looking for. They also have many examples and tutorials.
