<p>Bootstrap <code>border-{color}</code> utilities are generated with Sass using CSS variables. This allows for real-time color changes without compilation and dynamic alpha transparency changes.</p>
<h3 id="how-it-works">How it works<a class="anchor-link" aria-label="Link to this section: How it works" href="#how-it-works"> </a></h3>
<p>Consider our default <code>.border-success</code> utility.</p>

<p>We use an RGB version of our <code>--bs-success</code> (with the value of <code>25, 135, 84</code>) CSS variable and attached a second CSS variable, <code>--bs-border-opacity</code>, for the alpha transparency (with a default value <code>1</code> thanks to a local CSS variable). That means anytime you use <code>.border-success</code> now, your computed <code>color</code> value is <code>rgba(25, 135, 84, 1)</code>. The local CSS variable inside each <code>.border-*</code> class avoids inheritance issues so nested instances of the utilities don’t automatically have a modified alpha transparency.</p>
<h3 id="example">Example<a class="anchor-link" aria-label="Link to this section: Example" href="#example"> </a></h3>
<p>To change that opacity, override <code>--bs-border-opacity</code> via custom styles or inline styles.</p>
