Widely used CSS features to remove

[LeaVerou]

There have been plenty of excellent suggestions already, so we should consider what we could remove to make space for adding questions about new features.
Issue #11 already discusses removing the HTML questions, and #10 discusses removing the Houdini JS API questions.
However, there are a few CSS features that are very widely used and we don't gain very much insight asking about them.

The features with > 90% usage in 2021 were:

• Flexbox
• calc()

So it seems reasonable that these could be removed. Are there any others that could be safely removed?

RESOLVED:

Removed:

• Flexbox
• calc()
• Multi-column (not new, if people don't use it at this point it's because they don't need it)
• CSS Shapes
• overflow-anchor
• pointer-events
• initial-letter

Also marked the following as at-risk:

• CSS masks
• clip-path
• touch-action
• font-variant-*
• contain

Going through the final version of the survey, I wonder about removing object-fit too. This has not been cutting edge for over a decade, at this point whoever doesn't use it, just doesn't need it.
