WCAG Requirement

Content can be presented without loss of information or functionality, and without requiring scrolling in two dimensions, at 320 CSS pixels wide (or 256 CSS pixels tall for horizontal content).

Experience Builder Notes

EB apps with fixed layouts often fail reflow. Maps are exempt as 2D scrolling is essential. Our zoom test partially covers this.

Sufficient Techniques

✓Use responsive design patterns
✓Test at 320px viewport width

Common Failures in EB Apps

✗Side panel content cut off at narrow widths
✗Horizontal scrolling required for tables
