CSS Stacking Context inspector

Have you ever tried to use the z-index property, just to find out that, no matter how high you set it, it won't work as expected? That's because the z-index property relies on an implicit concept called "stacking contexts". After looking up what they are and how they work (informations you can find on MDN), you can use this devtools extension to inspect these contexts and troubleshoot any z-index problem you might face.

This extension will add a new panel that will show stacking contexts in a tree view, and will also append a new sidebar to the elements panel with some useful information about the selected element.
