It’s all CSS, all the time today. Go style something.
CSS3 Generator. Don’t know if I’ve already linked to this tool, but it is a great way to play with some of the new CSS3 properties. You see a preview of what you’re doing, and get the code for it. As you make additional selections, they are added to the preview.
This preview from CSS3 Generator shows the effect of a transform rule, a text-shadow rule, and a border-radius rule. If you don’t want the CSS3 rules to continue to apply to the preview area, simply refresh the page and start over.
CSS3 Transform to Matrix Filter Converter. This tool does the math for you to translate your simple CSS3 transforms syntax into a Matrix filter value for IE 6 through 8. A great tool!
