Layers

This extension installs a small button, which when clicked, applies a custom stylesheet on the web page you are viewing. The stylesheet is constructed in such a way that you'll immediately get a better understanding of how the page's different elements relate to each other, where they overlap, and how deeply they are nested - the darker the color, the deeper the nesting. This is useful for CSS debugging, as you can see at a glance which page elements need further fine-tuning.
