Toolbar: Provide a CSS custom property for the admin bar height.

ryelle · ryelle · commit ebe147cb133b · 2021-08-26T18:23:49.000Z
This new custom property, `--wp-admin--admin-bar--height`, reflects the admin bar's height and adjusts responsively on smaller screens. It can be used to offset content to avoid overlapping the admin bar, without needing to copy the media query. This also removes a workaround only needed for Internet Explorer 6 and below. Props nico23, sabernhardt. Fixes #52623. git-svn-id: https://develop.svn.wordpress.org/trunk@51672 602fd350-edb4-49c9-b593-d223f7449a82
