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:

--cui-nav-link-padding-x: #{$nav-link-padding-x};
--cui-nav-link-padding-y: #{$nav-link-padding-y};
@include rfs($nav-link-font-size, --cui-nav-link-font-size);
--cui-nav-link-font-weight: #{$nav-link-font-weight};
--cui-nav-link-color: #{$nav-link-color};
--cui-nav-link-hover-color: #{$nav-link-hover-color};
--cui-nav-link-disabled-color: #{$nav-link-disabled-color};

On the .nav-tabs modifier class:

--cui-nav-tabs-border-width: #{$nav-tabs-border-width};
--cui-nav-tabs-border-color: #{$nav-tabs-border-color};
--cui-nav-tabs-border-radius: #{$nav-tabs-border-radius};
--cui-nav-tabs-link-hover-border-color: #{$nav-tabs-link-hover-border-color};
--cui-nav-tabs-link-active-color: #{$nav-tabs-link-active-color};
--cui-nav-tabs-link-active-bg: #{$nav-tabs-link-active-bg};
--cui-nav-tabs-link-active-border-color: #{$nav-tabs-link-active-border-color};

On the .nav-pills modifier class:

--cui-nav-pills-border-radius: #{$nav-pills-border-radius};
--cui-nav-pills-link-active-color: #{$nav-pills-link-active-color};
--cui-nav-pills-link-active-bg: #{$nav-pills-link-active-bg};

Added in v5.0.0

On the .nav-underline modifier class:

--cui-nav-underline-gap: #{$nav-underline-gap};
--cui-nav-underline-border-width: #{$nav-underline-border-width};
--cui-nav-underline-link-active-color: #{$nav-underline-link-active-color};

Added in v5.0.0

On the .nav-underline-border modifier class:

--cui-nav-underline-border-gap: #{$nav-underline-border-gap};
--cui-nav-underline-border-border-color: #{$nav-underline-border-border-color};
--cui-nav-underline-border-border-width: #{$nav-underline-border-border-width};
--cui-nav-underline-border-link-padding-x: #{$nav-underline-border-link-padding-x};
--cui-nav-underline-border-link-padding-y: #{$nav-underline-border-link-padding-y};
--cui-nav-underline-border-link-color: #{$nav-underline-border-link-color};
--cui-nav-underline-border-link-active-color: #{$nav-underline-border-link-active-color};
--cui-nav-underline-border-link-disabled-color: #{$nav-underline-border-link-disabled-color};
