A Chrome DevTools Extension that displays stacking contexts and z-index values in the elements panel

Image from store z-context
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 -------- v3.0.0 - Update to manifest v3 and update stacking context rules https://github.com/gwwar/z-context/pull/29 v2.1.0 - Includes http protocol to facilitate development use cases https://github.com/gwwar/z-context/pull/23 v2.0.0 - Adds support for inspecting iframes https://github.com/gwwar/z-context/pull/21 https://github.com/gwwar/z-context/pull/22 v1.1.0 - Adds z-index stacking context rules as of 2021. Adds fixes for position sticky and shadow dom, props to roperzh and edenilan! See pulls 10, 17 and 18 at https://github.com/gwwar/z-context. v1.0.4 - fixes will-change case. a stacking context is created for opacity/transform but not other values https://github.com/gwwar/z-context/pull/9 v1.0.3 - fixes display reason for flex-items https://github.com/gwwar/z-context/pull/4 v1.0.2 - adds new z-index rules, fixes a bug when inspecting a shadow dom elements. https://github.com/gwwar/z-context/pull/3 v1.0.1 - fix reason message for non-static positions, props to giuseppeg. https://github.com/gwwar/z-context/pull/1

  • (2024-12-17) Noah Yamamoto: Works, but as other reviews stated it requires a full browser restart otherwise it just shows whitespace.
  • (2024-12-08) 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.
  • (2024-01-10) Michael Rosa: Doesn't work in: Chrome 120.0.6099.217 Chrome 121.0.6167.47 Chrome 122.0.6238.0
  • (2024-01-02) Andrei Kurhan: doesn't work in the Chrome v120
  • (2023-11-24) Nic Newdigate: does work unfortunately!
  • (2023-03-04) Zachary Wiles: 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.

  • (2019-02-10) wesh cousin: 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.

  • (2018-12-05) Ivan Fedulov: 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).

  • (2018-09-05) Ben McCallum: Great to understand/debug your z-indexes and stacking contexts. Should def be in DevTools natively :) Thanks heaps.

  • (2017-12-04) 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"
