CSS variables

React navs use local CSS variables on .nav, .nav-tabs, .nav-pills, .nav-underline and .nav-underline-border for enhanced real-time customization. Values for the CSS variables are set via Sass, so Sass customization is still supported, too.

On the .nav base class:

scss

$nav-tokens: defaults(
  (
    --cui-nav-gap: 0,
    --cui-nav-link-gap: .5rem,
    --cui-nav-link-align: center,
    --cui-nav-link-justify: center,
    --cui-nav-link-border-radius: var(--cui-radius-5),
    --cui-nav-link-padding-x: 1rem,
    --cui-nav-link-padding-y: #{$nav-link-padding-y},
    --cui-nav-link-font-size: inherit,
    --cui-nav-link-font-weight: inherit,
    --cui-nav-link-color: var(--cui-fg-2),
    --cui-nav-link-hover-color: var(--cui-fg-1),
    --cui-nav-link-hover-bg: var(--cui-bg-1),
    --cui-nav-link-active-color: var(--cui-fg-body),
    --cui-nav-link-active-bg: var(--cui-bg-2),
    --cui-nav-link-disabled-color: var(--cui-fg-4),
    --cui-nav-link-transition-property: #{color, background-color, border-color},
    --cui-nav-link-transition-duration: .15s,
    --cui-nav-link-transition-timing: ease-in-out,
  ),
  $nav-tokens
);

On the .nav-tabs modifier class:

scss

$nav-tabs-tokens: defaults(
  (
    --cui-nav-tabs-border-width: var(--cui-border-width),
    --cui-nav-tabs-border-color: #{$nav-tabs-border-color},
    --cui-nav-tabs-border-radius: var(--cui-radius-5),
    --cui-nav-tabs-link-hover-border-color: #{var(--cui-border-subtle) var(--cui-border-subtle) $nav-tabs-border-color},
    --cui-nav-tabs-link-active-color: var(--cui-fg-body),
    --cui-nav-tabs-link-active-bg: #{$nav-tabs-link-active-bg},
    --cui-nav-tabs-link-active-border-color: #{var(--cui-border-color) var(--cui-border-color) $nav-tabs-link-active-bg},
  ),
  $nav-tabs-tokens
);

On the .nav-pills modifier class:

scss

$nav-pills-tokens: defaults(
  (
    --cui-nav-pills-border-radius: 3rem,
    --cui-nav-pills-link-active-color: var(--cui-primary-contrast),
    --cui-nav-pills-link-active-bg: var(--cui-primary-bg),
  ),
  $nav-pills-tokens
);

Added in v5.0.0

On the .nav-underline modifier class:

scss

$nav-underline-tokens: defaults(
  (
    --cui-nav-underline-gap: 1rem,
    --cui-nav-underline-border-width: .125rem,
    --cui-nav-underline-link-active-color: var(--cui-fg-body),
  ),
  $nav-underline-tokens
);

Added in v5.0.0

On the .nav-underline-border modifier class:

scss

$nav-underline-border-tokens: defaults(
  (
    --cui-nav-underline-border-gap: .5rem,
    --cui-nav-underline-border-border-color: var(--cui-border-color),
    --cui-nav-underline-border-border-width: .125rem,
    --cui-nav-underline-border-link-padding-x: .5rem,
    --cui-nav-underline-border-link-padding-y: .5rem,
    --cui-nav-underline-border-link-color: var(--cui-fg-2),
    --cui-nav-underline-border-link-active-color: var(--cui-primary-base),
    --cui-nav-underline-border-link-disabled-color: var(--cui-fg-3),
  ),
  $nav-underline-border-tokens
);

How to use CSS variables

const customVars = {
  '--cui-nav-link-color': '#555',
  '--cui-nav-link-disabled-color': '#afaeef',
}

return <CTabs style={customVars}>{/* Tabs content */}</CTabs>

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

$nav-link-padding-y:                .5rem !default;

$nav-tabs-border-color:             var(--cui-border-color) !default;
$nav-tabs-link-active-bg:           var(--cui-bg-body) !default;
