Custom tooltips#

You can customize the appearance of tooltips using CSS variables. We set a custom style to scope our custom appearance and use it to override some of the local CSS variables.

const customTooltipStyle = {
  '--cui-tooltip-bg': 'var(--cui-primary)',
}
return (
  <CTooltip
    content="This top tooltip is themed via CSS variables."
    placement="top"
    style={customTooltipStyle}
  >
    <CButton color="secondary">Custom tooltip</CButton>
  </CTooltip>
)

Directions#

Hover over the buttons below to see the four tooltips directions: top, right, bottom, and left. Directions are mirrored when using CoreUI in RTL.

<CTooltip
  content="Vivamus sagittis lacus vel augue laoreet rutrum faucibus."
  placement="top"
>
  <CButton color="secondary">Tooltip on top</CButton>
</CTooltip>
<CTooltip
  content="Vivamus sagittis lacus vel augue laoreet rutrum faucibus."
  placement="right"
>
  <CButton color="secondary">Tooltip on right</CButton>
</CTooltip>
<CTooltip
  content="Vivamus sagittis lacus vel augue laoreet rutrum faucibus."
  placement="bottom"
>
  <CButton color="secondary">Tooltip on bottom</CButton>
</CTooltip>
<CTooltip
  content="Vivamus sagittis lacus vel augue laoreet rutrum faucibus."
  placement="left"
>
  <CButton color="secondary">Tooltip on left</CButton>
</CTooltip>

Usage#

Disabled elements#

Elements with the disabled attribute aren’t interactive, meaning users cannot focus, hover, or click them to trigger a tooltip (or popover). As a workaround, you’ll want to trigger the tooltip from a wrapper <div> or <span>, ideally made keyboard-focusable using tabindex="0".

<CTooltip
  content="Disabled tooltip"
  trigger={['hover', 'focus']}
>
  <span className="d-inline-block" tabIndex={0}>
    <CButton color="primary" disabled>Disabled button</CButton>
  </span>
</CTooltip>

Customizing#

CSS variables#

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

--cui-tooltip-zindex: #{$zindex-tooltip};
--cui-tooltip-max-width: #{$tooltip-max-width};
--cui-tooltip-padding-x: #{$tooltip-padding-x};
--cui-tooltip-padding-y: #{$tooltip-padding-y};
--cui-tooltip-margin: #{$tooltip-margin};
@include rfs($tooltip-font-size, --cui-tooltip-font-size);
--cui-tooltip-color: #{$tooltip-color};
--cui-tooltip-bg: #{$tooltip-bg};
--cui-tooltip-border-radius: #{$tooltip-border-radius};
--cui-tooltip-opacity: #{$tooltip-opacity};
--cui-tooltip-arrow-width: #{$tooltip-arrow-width};
--cui-tooltip-arrow-height: #{$tooltip-arrow-height};

How to use CSS variables#

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

SASS variables#

$tooltip-font-size:                 $font-size-sm !default;
$tooltip-max-width:                 200px !default;
$tooltip-color:                     var(--cui-body-bg) !default;
$tooltip-bg:                        var(--cui-emphasis-color) !default;

$tooltip-arrow-width:               .8rem !default;
$tooltip-arrow-height:              .4rem !default;
// fusv-disable
$tooltip-arrow-color:               null !default; // Deprecated in Bootstrap 4.2.0 for CSS variables
