Overview
Product summary
Review the store description, core capabilities, and common use cases.
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

Not working in chrome 2021
Doesn't work on latest chrome. Reloading the browser or reinstalling the extension doesn't help - the tab is always empty
Not work in 2021
If i set position value fixed or sticky and z-index: auto > it return false > you need to fix this bug
This extension helped me to understand and fix a problem with layers which I couldn't solve otherwise.
did not work, does not appear in dev tools even after restart, a how to would be nice
Thanks. Was going crazy trying to figure out why a stacking context was getting created and this one told me exactly why.
Crazy useful. Can't dev Webapps without it anymore
could not figure out how to use if :(
Super handy.
