Conveying meaning to assistive technologies

Using color to add meaning only provides a visual indication, which will not be conveyed to users of assistive technologies – such as screen readers. Ensure that information denoted by the color is either obvious from the content itself (e.g. the visible text), or is included through alternative means, such as additional text hidden with the .visually-hidden class.

Customizing#

CSS variables#

React callouts use local CSS variables on .callout for enhanced real-time customization. Values for the CSS variables are set via Sass, so Sass customization is still supported, too.

--cui-callout-padding-x: #{$callout-padding-x};
--cui-callout-padding-y: #{$callout-padding-y};
--cui-callout-margin-x: #{$callout-margin-x};
--cui-callout-margin-y: #{$callout-margin-y};
--cui-callout-border-width: #{$callout-border-width};
--cui-callout-border-color: #{$callout-border-color};
--cui-callout-border-left-width: #{$callout-border-left-width};
--cui-callout-border-radius: #{$callout-border-radius};

How to use CSS variables#

const vars = { 
  '--my-css-var': 10,
  '--my-another-css-var': "red" 
}
return <CCallout style={vars}>...</CCallout>

SASS variables#
