If overriding focus styles, use *:focus { outline: 3px solid transparent } to support Windows High Contrast Mode

Quick Tips for High Contrast Mode

  • Sarah Higley shares some tips for supporting Windows High Contrast Mode (WHCM). WHCM ignores ARIA roles/states/properties, so <a role="button"> will be styled as a link. Use svg { fill: currentColor } to have it match the color of the surrounding text. Beware that the -ms-high-contrast media query is being retired in favour of forced-colors, which is still experimental; current advice is to avoid using media queries at all.
