- Updates mentions of number and exact tiers
- Updates grid example to include xxl container
- Adds some scss-docs references
- Cleans up other grid mentions and docs
- Updates navbar example to include an expand at XXL variant
- in particular, controls that just relied on `placeholder`, as this is still not officially/consistently supported as a valid way to provide an accessible name (though some browsers do use it as a fallback)
* Follow-up to #29095
This PR fixes the responsive containers that were added in #29095, originally stubbed out in #25631. Apologies to @browner12 for getting that wrong.
Fixes#25631.
* update navbar as well because we cannot reset all containers uniformly
* Update navbars example to include container-xl example to ensure containers match
* rewrite responsive containers docs, add table of max-widths
* Update container docs
- Move table up to the intro
- Remove the container example because it's actually hella confusing
- Update and link to grid example as a demo instead
