Support CoreUI Development

CoreUI is an MIT-licensed open source project and is completely free to use. However, the amount of effort needed to maintain and develop new features for the project is not sustainable without proper financial backing.

You can support our Open Source software development in the following ways:

Buy the CoreUI PRO, and get access to PRO components, and dedicated support.

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.

1--cui-tooltip-zindex: #{$zindex-tooltip};
2--cui-tooltip-max-width: #{$tooltip-max-width};
3--cui-tooltip-padding-x: #{$tooltip-padding-x};
4--cui-tooltip-padding-y: #{$tooltip-padding-y};
5--cui-tooltip-margin: #{$tooltip-margin};
6--cui-tooltip-font-size: #{$tooltip-font-size};
7--cui-tooltip-color: #{$tooltip-color};
8--cui-tooltip-bg: #{$tooltip-bg};
9--cui-tooltip-border-radius: #{$tooltip-border-radius};
10--cui-tooltip-opacity: #{$tooltip-opacity};
11--cui-tooltip-arrow-width: #{$tooltip-arrow-width};
12--cui-tooltip-arrow-height: #{$tooltip-arrow-height};

How to use CSS variables#

1const vars = { 
2  '--my-css-var': 10,
3  '--my-another-css-var': "red" 
4}
5return <CTooltip style={vars}>...</CTooltip>

SASS variables#

1$tooltip-font-size:                 $font-size-sm;
2$tooltip-max-width:                 200px;
3$tooltip-color:                     $high-emphasis-inverse;
4$tooltip-bg:                        $black;
5$tooltip-border-radius:             $border-radius;
6$tooltip-opacity:                   .9;
7$tooltip-padding-y:                 $spacer * .25;
8$tooltip-padding-x:                 $spacer * .5;
9$tooltip-margin:                    null;
