Easily diff the styles being applied to any pair of DOM elements.
Avoid scrolling through the style inspector, trying to figure out what styles differ between two elements. This tool does so automatically — the diff of the last two “inspected” elements will be rendered by default. Just click on two in the inspector view, as seen in the screenshot. Still rough around the edges — if you use this I’d love feedback at https://github.com/mtn/difftool
