A Chrome DevTools Extension that displays stacking contexts and z-index values in the elements panel
Image from store
Description from store
Why use it? Browsers support a hierarchy of stacking contexts, rather than a single global one. This means that z-index values are often used incorrectly, and arbitrarily high values get set.
By Using Z-Context, you'll know:
- If the current element creates a stacking context, and why
- What its parent stacking context is
- The z-index value

- Works, but as other reviews stated it requires a full browser restart otherwise it just shows whitespace.
- Auri
- Getting an error about a failed network request in the latest version of Chrome. Definitely a red-flag as there's nothing here that requires any network operations. Uninstalling.

- Doesn't work in: Chrome 120.0.6099.217 Chrome 121.0.6167.47 Chrome 122.0.6238.0

- I have found that z-context v2.1.0 doesn't work (empty panel) upon first install until the browser is restarted. Temp fix: restart chrome browser after install. FAQ: Where does the Z-index panel appear? On the panel row with the Styles tab, at the very end, probably need to click the disclosure >> You can then rearrange by dragging the tab left.

- Doesn't work on latest chrome. Reloading the browser or reinstalling the extension doesn't help - the tab is always empty

- Thanks. Was going crazy trying to figure out why a stacking context was getting created and this one told me exactly why.

- I guess this extension might be useful, but it doesn't show every stacking contexts. In my case it didn't show that positioning an element to fixed or sticky creates a stacking context, even without any opacity or z-index rule. as it can be seen here https://developer.mozilla.org/en-US/docs/Web/CSS/CSS_Positioning/Understanding_z_index/The_stacking_context and as it definitely applies.

- Occurred to be very helpful when I stuck with debugging z-index issue in markup. Would be very nice if displayed properties *current* and *parentStackingContext* will point to real DOM nodes in Elements tab, not just strings with class names (which sometimes are absent when element has inline styles).

- You have to completely restart Chrome for this extension to start working. Took me a while to figure that out.

- Dmitri Pisarev
- This extension is very helpful. But I wasted a ton of time because of the bug in it. It reports new stacking context for any value of "will-change", even smth like "will-change: left", which obviously doesn't create a stacking context. According to the spec: "Element with a will-change value specifying any property that would create a stacking context on non-initial value"

- Perfect to find out which stacking context an element belongs to.
