We'd like to adopt codex styles to replace mw-ui-button ,mw-ui-icon and typeahead search by changing our markup to match CSS components (see https://gerrit.wikimedia.org/r/c/mediawiki/skins/Vector/+/912974 and T322077)
The goal of the spike is to identify remaining blockers (if any)
TODO
- Change the markup the CSS component markup
- Run Pixel
- Document the changes and identify recommended way to fix them.
- Document the expected change in bytes for render blocking CSS
