Some Suggestions of MDN

Here is a short list of suggestions:

Could the search bar be clickable to run search after inputting text.

Have pages that are a collective list for each of these sections.
See Also
Accessibility Concerns

Offsite links such as these here but all on one page.
See Also Transform
See Also Gradients

There may be an issue here, @support and @document shouldn’t be listed under media queries. It may be similar to what was noted here about multiple groupings interfering with modules.

On this page here, would it be possible to clarify “almost all” for the list, readonly, and required attributes. (Could possibly use a negative definition as in “All except …”.)
