Form control with absolute font size Accessibility Checkpoint

Description

Text-based form controls with absolute font sizes do not resize correctly.

Help

Absolute units are CM, MM, IN, PC and PT. When used with fonts PX is also considered an absolute unit, because it isn’t relative the user’s preferred font size. Low-vision users, and a lot of people over 50, increase the browser default font size to make text easier to read, but the text on this form may not resize correctly.

Applicable standards

Note: Section 508 Refresh (2017) checkpoints are equivalent to WCAG 2.0 level A and level AA checkpoints.
