Borders

Basic border utility classes with module mixins for compiling responsive modifier classes.

Examples

.bd

.bd-t

.bd-b

.bd-s

.bd-e

.bd-y

.bd-x

Example HTML

<div class="bd">.bd</div>
<div class="bd-t py-3">.bd-t</div>
<div class="bd-b py-3">.bd-b</div>
<div class="bd-s py-3">.bd-s</div>
<div class="bd-e py-3">.bd-e</div>
<div class="bd-y py-3">.bd-y</div>
<div class="bd-x py-3">.bd-x</div>

.rd-1

.rd-2

.rd-3

.rd-4

.rd-5

.rd-pill

Example HTML

<div class="rd-1 bd py-3">.rd-1</div>
<div class="rd-2 bd py-3">.rd-2</div>
<div class="rd-3 bd py-3">.rd-3</div>
<div class="rd-4 bd py-3">.rd-4</div>
<div class="rd-5 bd py-3">.rd-5</div>
<div class="rd-pill bd py-3">.rd-pill</div>

.rd-5-top

.rd-5-bottom

.rd-5-start

.rd-5-end

Example HTML

<div class="rd-5-top bd py-3">.rd-5-top</div>
<div class="rd-5-bottom bd py-3">.rd-5-bottom</div>
<div class="rd-5-start bd py-3">.rd-5-start</div>
<div class="rd-5-end bd py-3">.rd-5-end</div>

Example HTML

<div class="rd-circle bd" style="width: 6rem; height: 6rem;"></div>

Using the module

Add the sassmods.scss to your custom styles as below then include the Sass mixin anywhere below.

custom.scss

@use "sassmods/scss/sassmods" as *;
@include borders-css;

Borders also have responsive modifier mixins that can be included in custom breakpoints:

custom.scss

@use "sassmods/scss/sassmods" as *;
@include borders-css;
@media (max-width: 480px) {
  @include borders-sm-css;
}

See customizing for information about using the Sass and CSS variables in the source code (see below) to customize the styles, and Sass variables (on the using SassMods page) for other ways to use the variables to create custom styles.
