Bug 103336 – [CSS Grid Layout] Rename grid-{rows|columns} to grid-definition-{rows|columns}

• Component: Layout and Rendering
• Status: RESOLVED FIXED

[Julien Chaffraix]

The specification changed these names since we implemented them.

It's probably too early to do it as the specification didn't stabilize enough.

[Martin Robinson]

Looks like the latest version of the spec [1] keeps this name, so perhaps it's safe to at least add an alias now.

I've updated grid layout tests to reflect the new naming, but didn't update the ietestcenter tests. I figured it would be better to both keep the imported tests similar and to keep some coverage for the old name. I'm happy to change things around if this isn't the preferred approach.

Since we're not exposing this by default IMO it's OK just to rename them breaking compatibility with the old names instead of adding aliases.

Also consider changing all the references in the tests to the old names, there are several test descriptions that mention grid-rows and/or grid-columns. As far as I saw this involves changing the expected results of two tests as well

grid-element-change-rows-repaint.html

This still talks about aliasing.
