Known errors;

  • Very small text.
  • Very low contrast between the text and background.
  • Empty alternative text: images don’t have an alternative text which is necessary in case the image doesn’t load in some devices
  • Redundant title, the title should be different from the alternative text which is more descriptive of what is going on with the text or image.
  • Broken ARIA menus
  • Empty buttons
  • Redundant links
  • Redundant title text
  • Skipped heading level; titles don’t follow a hierarchal order e.g. h1 title shouldn’t be followed by a h3 title so it should be h1 followed by h2 then h3.
