Opacity

Added in v5.2.0

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

How it works

Consider our default .border-success utility.

.border-success {
  --bs-border-opacity: 1;
  border-color: rgba(var(--bs-success-rgb), var(--bs-border-opacity)) !important;
}

We use an RGB version of our --bs-success (with the value of 25, 135, 84) CSS variable and attached a second CSS variable, --bs-border-opacity, for the alpha transparency (with a default value 1 thanks to a local CSS variable). That means anytime you use .border-success now, your computed color value is rgba(25, 135, 84, 1). The local CSS variable inside each .border-* class avoids inheritance issues so nested instances of the utilities don’t automatically have a modified alpha transparency.

Example

To change that opacity, override --bs-border-opacity via custom styles or inline styles.

This is default success border

This is 50% opacity success border

html

<div class="border border-success p-2 mb-2">This is default success border</div>
<div class="border border-success p-2" style="--bs-border-opacity: .5;">This is 50% opacity success border</div>

Or, choose from any of the .border-opacity utilities:

This is default success border

This is 75% opacity success border

This is 50% opacity success border

This is 25% opacity success border

This is 10% opacity success border

html

<div class="border border-success p-2 mb-2">This is default success border</div>
<div class="border border-success p-2 mb-2 border-opacity-75">This is 75% opacity success border</div>
<div class="border border-success p-2 mb-2 border-opacity-50">This is 50% opacity success border</div>
<div class="border border-success p-2 mb-2 border-opacity-25">This is 25% opacity success border</div>
<div class="border border-success p-2 border-opacity-10">This is 10% opacity success border</div>

Width

html

<span class="border border-1"></span>
<span class="border border-2"></span>
<span class="border border-3"></span>
<span class="border border-4"></span>
<span class="border border-5"></span>

Radius

Add classes to an element to easily round its corners.

html

<img src="..." class="rounded" alt="...">
<img src="..." class="rounded-top" alt="...">
<img src="..." class="rounded-end" alt="...">
<img src="..." class="rounded-bottom" alt="...">
<img src="..." class="rounded-start" alt="...">
<img src="..." class="rounded-circle" alt="...">
<img src="..." class="rounded-pill" alt="...">

Sizes

Use the scaling classes for larger or smaller rounded corners. Sizes range from 0 to 5, and can be configured by modifying the utilities API.

html

<img src="..." class="rounded-0" alt="...">
<img src="..." class="rounded-1" alt="...">
<img src="..." class="rounded-2" alt="...">
<img src="..." class="rounded-3" alt="...">
<img src="..." class="rounded-4" alt="...">
<img src="..." class="rounded-5" alt="...">
