Use border utilities to quickly style the border and border-radius of an element. Great for images, buttons, or any other element.

Border

You may use border utilities to add or remove an element’s borders. Choose from all borders or one at a time.

        <span class="border border-primary"></span>
        <span class="border border-secondary"></span>
        <span class="border border-success"></span>
        <span class="border border-danger"></span>
        <span class="border border-warning"></span>
        <span class="border border-info"></span>
        <span class="border border-light"></span>
        <span class="border border-dark"></span>
        <span class="border border-white"></span>

      

Border-radius

Finally, you can add classes to an element to easily round its corners.

100x100 100x100 100x100 100x100 100x100 100x100 100x100 100x100


        <img src="..." alt="..." class="rounded mb-0">
        <img src="..." alt="..." class="rounded-top">
        <img src="..." alt="..." class="rounded-right">
        <img src="..." alt="..." class="rounded-bottom">
        <img src="..." alt="..." class="rounded-left">
        <img src="..." alt="..." class="rounded-circle">
        <img src="..." alt="..." class="rounded-pill">
        <img src="..." alt="..." class="rounded-0">

      

Sizes

Use .rounded-lg or .rounded-sm for larger or smaller border-radius.

100x100 100x100


        <img class="rounded-sm" alt="100x100" src="...">
        <img class="rounded-lg" alt="100x100" src="...">
