Show Your Bones: XRAY Your Website

I just got my hands on what is quickly becoming my favorite web tool. XRAY is like a lightweight Web Developer toolbar that provides front-end coders with a quick debugging tool. No download is necessary; XRAY is executable via a bookmarklet that launches a floating tool panel over your web page. Selecting any element on your page reveals its style information—including style name, hierarchy inheritance, floats, margins, etc. I’ll continue to use the developer toolbar and Firebug, but there’s no need to pull out the entire toolbox when all you need is a pair of pliers.
