Xyle scope is an interesting addition to the tool-belt of any XHTML/CSS worker who happens to use OS X. With this desktop app, you'll find the ability to select elements of any web page, see the margin/padding relationship applied to it, and a list of all styles that effect it. You'll see a multi-column finder-eske navigation to browse the HTML elements of the page - a very effective way to see the structure. You might even have reason to consult the built-in DTD browser.

What I like about this most is it's ability to decipher the CSS that is being applied to any particular element, including styles applied to parent elements. As a diagnostic tool, this might be the best all-in-one solution I've seen yet. The fact that you can tweak settings in the CSS and preview instantly and export in a number of ways is even more reason to give this a try. Link found at coolosxapps.
