Border colors
Border utilities add or remove borders and set their colour, width and roundness.
In this page:
Syntax
<div class="border border-primary">all sides</div>
<div class="border-top border-danger">top only</div>Border colors
.border adds a border on all sides, .border-top and friends target sides, and .border-0 removes them. Colour with .border-primary, width with .border-1 to .border-5, and radius with .rounded, .rounded-circle and .rounded-pill.
Subtle border colours end with -subtle.
Note:
rounded-circle needs equal width and height to make a true circle.
