Official methodology to test criterion 10.11

Test 1 (10.11.1)

  1. Find the information and functions in the document if its content is designed to scroll vertically (the text reading direction is horizontal).
  2. Reduce the display window to a width of 320 px and check that the information and functions remain available without any horizontal scrolling.
