CSS variables

React Tooltip supports CSS variables for easy customization. These variables are set via Sass but allow direct overrides in your stylesheets or inline styles.

scss

$tooltip-tokens: defaults(
  (
    --cui-tooltip-zindex: var(--cui-z-tooltip),
    --cui-tooltip-max-width: 200px,
    --cui-tooltip-padding-x: calc(var(--cui-spacer) * .75),
    --cui-tooltip-padding-y: calc(var(--cui-spacer) * .375),
    --cui-tooltip-font-size: var(--cui-font-size-sm),
    --cui-tooltip-color: #{$tooltip-color},
    --cui-tooltip-bg: var(--cui-fg-body),
    --cui-tooltip-border-radius: var(--cui-radius-5),
    --cui-tooltip-opacity: .95,
    --cui-tooltip-arrow-width: .8rem,
    --cui-tooltip-arrow-height: .4rem,
    --cui-tooltip-transition-property: opacity,
    --cui-tooltip-transition-duration: .15s,
    --cui-tooltip-transition-timing: linear,
  ),
  $tooltip-tokens
);

How to use CSS variables

const customVars = {
  '--cui-tooltip-color': '#888',
  '--cui-tooltip-bg': '#f2f4f6',
}

return <CTooltip style={customVars}>{/* Tooltip content */}</CTooltip>

Sass variables

Deprecated in v6.0.0

Sass variables set these defaults at build time and are removed in v7. The CSS variables above reach the same values without recompiling, and can be set on a single element.

scss

$tooltip-color:                     var(--cui-bg-body) !default;
