- Creates new flexbox grid Sass file in our docs assets
- Updates the Gruntfile to compile said new Sass file and minify the output
- Update notice on flexbox docs page for how it works
- Only enable compiled flexbox grid CSS in hosted docs site, not in dev (for easier and specific debugging of all flexbox features)
Previously, when running the docs locally, the site, rooted at:
http://localhost:9001/
would reference docs assets using relative URLs such as:
/../assets/js/vendor/anchor.min.js
which is equivalent to:
http://localhost:9001/../assets/js/vendor/anchor.min.js
which is nonsense, since the root directory has no parent directory.
Apparently browsers silently ignore this extra '..', hence why this wasn't noticed until now.
But if you adjust Jekyll's `baseurl` setting, this mistake causes incorrect URLs to get generated.
This commit corrects the problem by removing the extra '../' from the paths.
These paths are also referenced in the Gruntfile, where the fix actually allows us to simplify the code.
Previously, in the Gruntfile, we were doing, e.g.:
path.join('./docs/assets', '../assets/js/vendor/anchor.min.js')
which calculates to:
./docs/assets/../assets/js/vendor/anchor.min.js
which can be simplified to:
./docs/assets/js/vendor/anchor.min.js
So we can remove the '/assets' suffix from the left argument
and the '../' prefix from the right argument
and still obtain the same result.
Refs #19990
Continues the degruntification process.
Also removes mq4-hover-shim for now,
since it doesn't yet implement the standard PostCSS plugin interface.
