Failure of Success Criterion 1.4.4 due to incorrect use of viewport units to resize text

@@ -20,8 +20,7 @@

Description

The objective of this technique is to document the failure of text to re-scale when viewport units are used on text. As these units are relative to the viewport, it means they cannot be resized by zooming or adjusting text-size.

There are various methods to increase and decrease the size of text and other content, but viewport units applied to text (generally via font-size in CSS) prevent most available methods. Attempts to use browser controls to zoom or adjust text-size will not work. Only methods that completely override the CSS will work, and those could cause other issues such as layouts collapsing or text overlapping.

Some uses of viewport units may not prevent text-size adjustments, but if they are used as the primary method for defining text-size, they are likely to cause a failure of Success Criterion 1.4.4.

If media queries were used to adjust the size of text or unit of measure at different screen sizes, it may not be a failure of Resize Text. On-page controls provided by the author are also a way of passing the resize text success criteria.
