This site aims to meet WCAG 2.2 at level AA. It has been checked by hand with a keyboard and in a browser, but it has not had an independent audit or testing with every screen reader.

What is in place

• Every control works from the keyboard and shows a visible focus ring.
• The page has header, main and footer landmarks and one top-level heading.
• All text meets a contrast ratio of at least 4.5 to 1 against its background.
• With reduced motion turned on, entrance animations and the moving background are off.
• The moving background rests after a few seconds without input.
• Copying a command and choosing a color are announced to screen readers.
• Color dots and hex chips keep their real colors in high contrast mode.

Known limitations

• Clicking a word in the code sample works with a mouse or touch only. From the keyboard, the color dots above the editor show the same thing.
• When a color is selected, the other words in the code dim below the usual contrast level. This is temporary and ends when you select again, click away or press Escape.
• On narrow screens the code sample scrolls sideways.
