Impact on users:

• JAWS Reading: Treats tables without TH and ROLE as layout tables if the table contains cells above or below certain pixel sizes. This measurement is affected by browser window size, browser font size, and the browser used.
• NVDA Reading: Applies a 'layout table' heuristic to tables without TH and ROLE which varies depending on the browser used and on the window size in some circumstances.
• VoiceOver Reading: Uses a sophisticated heuristic on tables without TH and ROLE, which is similar (but not identical) to the heuristic used by NVDA with Firefox.

Impact on users:

• JAWS : Reads out placeholder text, instead of a useful image description.
• NVDA : Reads out placeholder text, instead of a useful image description.
• VoiceOver : Reads out placeholder text, instead of a useful image description.

Some users find it hard to read light gray text on a white background, dark gray text on a black background and white text on a red background.

• The contrast ratio should be 3.0 or more for 18 point text, or larger
• The contrast ratio should be 3.0 or more for 14 point bold text, or larger
• The contrast ratio should be 4.5 or more for all other text

Using a border or outline style that obscures the focus ring causes problems for keyboard-only users in:

• Chrome (obscures the focus indicator on links, buttons, dropdowns and range controls)
• Firefox (obscures the focus indicator on links)
• Internet Explorer (obscures the focus indicator on links, buttons and range controls)

Some users find it hard to read light gray text on a white background, dark gray text on a black background and white text on a red background.

Note: The default link color in IE11 has poor contrast on a white background. Fix by specifying a:link and a:visited colors in CSS.

• The contrast ratio should be 4.5 or more for 18 point text, or larger
• The contrast ratio should be 4.5 or more for 14 point bold text, or larger
• The contrast ratio should be 7.0 or more for all other text
