Today's Obsession: Layer Styles
Here’s a tool for you visual learners at layerstyles.org: this is a tool that shows you, using the visual analogy of the familiar Photoshop layer styles dialog, some layer elements which can be edited in CS3. Check off the options you want—drop shadow, inner shadow, background, border, and rounded corners—then click okay. At the bottom, your newly-created CSS selectors are available in a little popout tab. This is a super simple tool for those of us (think: most of us) who need to see something and poke at it while we learn.
