XRAY is a super handy little bookmarklet that allows you to reveal the formatting of web page elements just by clicking around the page.
I’ve only used it with Safari, but since it’s just a bit of javascript, it should work with all modern browsers, on both platforms.
UPDATE: One of the XRAY developers left a comment saying that it doesn’t quite work in IE or Opera yet, but he’s working on it and should have a version soon. Thanks for the update, John.

thanks for the nice words.
At present it works on Mozilla an Webkit based browsers – I’ve got a version for IE mostly working, so hopefuly IE 6+ and Opera will be out very soon

That looks JUST like the element inspector in Safari 3.
