9.4 Level AA − WCAG 2.0 Success Criterion 1.4.4 − Resize text

Ensure all text can be resized up to 200% without the loss of content or functionality. In this way, persons with mild visual impairments can read the content without using assistive technologies such as a screen magnifier.

Before Rectification

After Rectification

By adding a function to change the text size in the masthead, text size can be easily resized. Alternately, ensure websites are built so that built in browser text size tools work as they should. Developers should also be mindful of using proper cascading style sheet (CSS) techniques to ensure the CSS works with the built in browser resize functions.
