Colorize text with color utilities. If you want to colorize links, you can use the [.link-*
helper classes]({{< docsref "/helpers/colored-links" >}}) which have :hover
and :focus
states.

Color utilities like .text-*
that generated from our original $theme-colors
Sass map don't yet respond to color modes, however, any .text-*-emphasis
utility will. This will be resolved in v6.
{{< /callout >}}
{{< example >}} {{< colors.inline >}} {{- range (index $.Site.Data "theme-colors") }}
.text-{{ .name }}
.text-{{ .name }}-emphasis
{{- end -}} {{< /colors.inline >}}.text-body
.text-body-emphasis
.text-body-secondary
.text-body-tertiary
.text-black
.text-white
.text-black-50
.text-white-50
{{< /example >}}{{< callout warning >}}
Deprecation: With the addition of .text-opacity-*
utilities and CSS variables for text utilities, .text-black-50
and .text-white-50
are deprecated as of v5.1.0. They'll be removed in v6.0.0.
{{< /callout >}}
{{< callout warning >}}
Deprecation: With the addition of the expanded theme colors and variables, the .text-muted
utility has been deprecated as of v5.3.0. Its default value has also been reassigned to the new --bs-secondary-color
CSS variable to better support color modes. It will be removed in v6.0.0.
{{< /callout >}}
{{< added-in "5.1.0" >}}
As of v5.1.0, text color utilities are generated with Sass using CSS variables. This allows for real-time color changes without compilation and dynamic alpha transparency changes.
Consider our default .text-primary
utility.
.text-primary {
--bs-text-opacity: 1;
color: rgba(var(--bs-primary-rgb), var(--bs-text-opacity)) !important;
}
We use an RGB version of our --bs-primary
(with the value of 13, 110, 253
) CSS variable and attached a second CSS variable, --bs-text-opacity
, for the alpha transparency (with a default value 1
thanks to a local CSS variable). That means anytime you use .text-primary
now, your computed color
value is rgba(13, 110, 253, 1)
. The local CSS variable inside each .text-*
class avoids inheritance issues so nested instances of the utilities don't automatically have a modified alpha transparency.
To change that opacity, override --bs-text-opacity
via custom styles or inline styles.
{{< example >}}
Or, choose from any of the .text-opacity
utilities:
{{< example >}}
Sometimes contextual classes cannot be applied due to the specificity of another selector. In some cases, a sufficient workaround is to wrap your element's content in a <div>
or more semantic element with the desired class.
In addition to the following Sass functionality, consider reading about our included [CSS custom properties]({{< docsref "/customize/css-variables" >}}) (aka CSS variables) for colors and more.
Most color
utilities are generated by our theme colors, reassigned from our generic color palette variables.
{{< scss-docs name="color-variables" file="scss/_variables.scss" >}}
{{< scss-docs name="theme-color-variables" file="scss/_variables.scss" >}}
Grayscale colors are also available, but only a subset are used to generate any utilities.
{{< scss-docs name="gray-color-variables" file="scss/_variables.scss" >}}
{{< scss-docs name="theme-text-map" file="scss/_maps.scss" >}}
Variables for setting colors in .text-*-emphasis
utilities in light and dark mode:
{{< scss-docs name="theme-text-variables" file="scss/_variables.scss" >}}
{{< scss-docs name="theme-text-dark-variables" file="scss/_variables-dark.scss" >}}
Theme colors are then put into a Sass map so we can loop over them to generate our utilities, component modifiers, and more.
{{< scss-docs name="theme-colors-map" file="scss/_variables.scss" >}}
Grayscale colors are also available as a Sass map. This map is not used to generate any utilities.
{{< scss-docs name="gray-colors-map" file="scss/_variables.scss" >}}
RGB colors are generated from a separate Sass map:
{{< scss-docs name="theme-colors-rgb" file="scss/_maps.scss" >}}
Color opacities build on that with their own map that's consumed by the utilities API:
{{< scss-docs name="utilities-text-colors" file="scss/_maps.scss" >}}
Color mode adaptive text colors are also available as a Sass map:
{{< scss-docs name="theme-text-map" file="scss/_maps.scss" >}}
{{< scss-docs name="theme-text-dark-map" file="scss/_maps.scss" >}}
Color utilities are declared in our utilities API in scss/_utilities.scss
. [Learn how to use the utilities API.]({{< docsref "/utilities/api#using-the-api" >}})
