<meta name="text-scale">Limited availability
The <meta name="text-scale" content="scale" /> HTML element allows the browser's initial font size to be affected by the operating system text scale settings. The <meta name="text-scale" content="legacy" /> element is the default behavior that respects only browser font-size settings.
Not yet supported in all major browsers — check the table and provide a fallback.
