1.4.4: Resize Text
Guideline 1.4.4 "Resize Text" under WCAG 2.0 requires that text must be resizable up to 200% without loss of content or functionality. This guideline ensures that users with visual impairments can increase the text size to improve readability without compromising the layout, functionality, or usability of the content. It is essential for making web content accessible to users with low vision.
Importance of 1.4.4: Resize Text Success Criterion
