AntiBigText

AntiBigText prevents text enlargement when using the largest breakpoint (1596+ px wide).

When using AntiBigText, text sizes at the largest breakpoint should be identical to text sizes at the other breakpoints. See the breakpoints and typography Staff blog post for breakpoint details.

Usage
Add the following line to your global.css page (for personal use on all wikis). It must be at the very top of the page (with any other @import rules you may have) to work.

You can also copy the contents of the MediaWiki:AntiBigText.css page to your CSS page, if you prefer.
