Content: Issue with "z-index": Syntax code block doesn't include 'revert' in the valid Global values

[0xdevalias]

MDN URL: https://developer.mozilla.org/en-US/docs/Web/CSS/z-index

What information was incorrect, unhelpful, or incomplete?

Within the code block that shows possible global values we see the following:

/* Global values */
z-index: inherit;
z-index: initial;
z-index: unset;

Yet it seems we can also use the global revert here as well:

Specific section or headline?

Syntax

What did you expect to see?

  /* Global values */
  z-index: inherit;
  z-index: initial;
+ z-index: revert;
  z-index: unset;

Did you test this? If so, how?

I can add it 👍

I'm not convinced that we ever added revert to any property page's global values (I think we just added it to the all page).

It would be good to start off by checking this, and if not, writing some kind of a script that could crawl through the css property pages and add it to all of them that need it.

agreed, seems like a job for a script. Then we can just keep an eye out for any that got missed. I've fixed a couple of syntax boxes that had something odd in them recently.

If we could compare a list of the pages this script caught with a list of all property pages then I could go round the ones that didn't get updated and find out why.
