Utilities

Built for Speed. Designed for Control.

Color & Background

Color and background helpers combine the power of our .text-* utilities and .bg-* utilities in one class. Using our Sass color-contrast() function, we automatically determine a contrasting color for a particular background-color.

Primary with contrasting color (.text-bg-primary)

Secondary with contrasting color (.text-bg-secondary)

Success with contrasting color (.text-bg-success)

Danger with contrasting color (.text-bg-danger)

Warning with contrasting color (.text-bg-warning)

Info with contrasting color (.text-bg-info)

Light with contrasting color (.text-bg-light)

Dark with contrasting color (.text-bg-dark)

Background Opacity

background-color utilities are generated with Sass using CSS variables. This allows for real-time color changes without compilation and dynamic alpha transparency changes.

This is default primary background

This is 75% opacity primary background

This is 50% opacity primary background

This is 25% opacity primary background

This is 10% opacity success background

This is default dark background

This is 75% opacity dark background

This is 50% opacity dark background

This is 25% opacity dark background

This is 10% opacity success background

Text Opacity Color

Text color utilities are generated with Sass using CSS variables. This allows for real-time color changes without compilation and dynamic alpha transparency changes.

This is default primary text

This is 75% opacity primary text

This is 50% opacity primary text

This is 25% opacity primary text

Opacity

The opacity property sets the opacity level for an element. The opacity level describes the transparency level, where 1 is not transparent at all, .5 is 50% visible, and 0 is completely transparent. Set the opacity of an element using .opacity-{value} utilities.

Border Radius

Add classes to an element to easily round its corners.

Pointer Events

Bootstrap provides .pe-none and .pe-auto classes to prevent or add element interactions.

This link can not be clicked.

This link can be clicked (this is default behavior).

This link can not be clicked because the pointer-events property is inherited from its parent. However, this link has a pe-auto class and can be clicked.

Border Radius Size

Use the scaling classes for larger or smaller rounded corners. Sizes range from 0 to 5.

Text Selection

Use user-select-all, user-select-auto, or user-select-none class to the content which is selected when the user interacts with it.

This paragraph will be entirely selected when clicked by the user.

This paragraph has default select behavior.

This paragraph will not be selectable when clicked by the user.

Overflow

Adjust the overflow property on the fly with four default values and classes. These classes are not responsive by default.

This is an example of using .overflow-auto on an element with set width and height dimensions. By design, this content will vertically scroll.

This is an example of using .overflow-hidden on an element with set width and height dimensions.

This is an example of using .overflow-visible on an element with set width and height add more text dimensions homer admin dashboard template.

This is an example of using .overflow-scroll on an element with set width and height dimensions.

Position in Arrange

Arrange elements easily with the edge positioning utilities. The format is {property}-{position}.

Position in Center

In addition, you can also center the elements with the transform utility class .translate-middle.

Position in Axis

By adding .translate-middle-x or .translate-middle-y classes, elements can be positioned only in horizontal or vertical direction.

Shadows

While shadows on components are disabled by default in Bootstrap and can be enabled via $enable-shadows, you can also quickly add or remove a shadow with our box-shadow utility classes. Includes support for .shadow-none and three default sizes (which have associated variables to match).

No shadow

Small shadow

Regular shadow

Larger shadow

Width

Width utilities are generated from the utility API in _utilities.scss. Includes support for 25%, 50%, 75%, 100%, and auto by default. Modify those values as you need to generate different utilities here.

Object Fit

Change the value of the object-fit property with our responsive object-fit utility classes. This property tells the content to fill the parent container in a variety of ways, such as preserving the aspect ratio or stretching to take up as much space as possible.

.object-fit-contain

.object-fit-cover

.object-fit-fill

.object-fit-scale

.object-fit-none

Z-index

Use z-index utilities to stack elements on top of one another. Requires a position value other than static, which can be set with custom styles or using our position utilities.
