Accessibility
Color contrast ratio for our Message Card components meets AA standards, based on Web Content Accessibility Guidelines (WCAG) guidelines.
Benefits: People with low vision often have difficulty reading text that does not contrast with its background. This can be exacerbated if the person has a color vision deficiency that lowers the contrast even further. Providing a minimum luminance contrast ratio between the text and its background can make the text more readable even if the person does not see the full range of colors. It also works for the rare individuals who see no color.¹
Message cards should display a visible focus state
