All sides

Use border utilities to add or remove an element’s borders. Choose from .border, .border-0, .border-2, .border-4, and .border-8 to set the border on all sides:

<div class="border"></div>
<div class="border border-0"></div>
<div class="border border-2"></div>
<div class="border border-4"></div>
<div class="border border-8"></div>

Individual sides

Or, use the .border-SIDE, .border-SIDE-0, .border-SIDE-2, .border-SIDE-4, and .border-SIDE-8 to set the border on one side only:

<span class="border"></span>
<span class="border-top"></span>
<span class="border-end"></span>
<span class="border-bottom"></span>
<span class="border-start"></span>

Responsive

Responsive variations also exist for each border value. Use the .border-{breakpoint}-{value} for sm, md, lg, xl, and xxl to any existing border utility.

<!-- All sides -->
<div class="border-md-4 ..."></div>

<!-- Individual side -->
<div class="border-top border-md-2 ..."></div>
