<strong>Deprecation:</strong> With the addition of <code>.text-opacity-*</code> utilities and CSS variables for text utilities, <code>.text-black-50</code> and <code>.text-white-50</code> are deprecated as of v5.1.0. They’ll be removed in v6.0.0.
</div>
<div class="bd-callout bd-callout-info">
<h5 id="conveying-meaning-to-assistive-technologies">Conveying meaning to assistive technologies</h5>
<p>Using color to add meaning only provides a visual indication, which will not be conveyed to users of assistive technologies – such as screen readers. Ensure that information denoted by the color is either obvious from the content itself (e.g. the visible text), or is included through alternative means, such as additional text hidden with the <code>.visually-hidden</code> class.
</div>
<h2 id="opacity">Opacity</h2>
<p><small class="d-inline-flex px-2 py-1 font-monospace text-muted border rounded-3">Added in v5.1.0</small></p>
<p>As of v5.1.0, text color 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</h3>
<p>Consider our default <code>.text-primary</code> utility.</p>
<div class="highlight"><pre tabindex="0" class="chroma"><code class="language-css" data-lang="css"><span class="p">.</span><span class="nc">text-primary</span> <span class="p">{</span>
<span class="nv">--bs-text-opacity</span><span class="p">:</span> <span class="mi">1</span><span class="p">;</span>
<span class="k">color</span><span class="p">:</span> <span class="nb">rgba</span><span class="p">(</span><span class="nf">var</span><span class="p">(</span><span class="o">--</span><span class="n">bs</span><span class="o">-</span><span class="n">primary</span><span class="o">-</span><span class="n">rgb</span><span class="p">),</span> <span class="nf">var</span><span class="p">(</span><span class="o">--</span><span class="n">bs</span><span class="o">-</span><span class="kc">text</span><span class="o">-</span><span class="n">opacity</span><span class="p">))</span> <span class="cp">!important</span><span class="p">;</span>
<span class="p">}</span>
</code></pre></div><p>We use an RGB version of our <code>--bs-primary</code> (with the value of <code>13, 110, 253</code>) CSS variable and attached a second CSS variable, <code>--bs-text-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>.text-primary</code> now, your computed <code>color</code> value is <code>rgba(13, 110, 253, 1)</code>. The local CSS variable inside each <code>.text-*</code> class avoids inheritance issues so nested instances of the utilities don’t automatically have a modified alpha transparency.</p>
<h3 id="example">Example</h3>
<p>To change that opacity, override <code>--bs-text-opacity</code> via custom styles or inline styles.</p>
<div class="bd-example">
<div class="text-primary">This is default primary text</div>
<div class="text-primary" style="--bs-text-opacity: .5;">This is 50% opacity primary text</div>
</div><div class="highlight"><pre tabindex="0" class="chroma"><code class="language-html" data-lang="html"><span class="p"><</span><span class="nt">div</span> <span class="na">class</span><span class="o">=</span><span class="s">"text-primary"</span><span class="p">></span>This is default primary text<span class="p"></</span><span class="nt">div</span><span class="p">></span>

<h2 id="specificity">Specificity</h2>
<p>Sometimes contextual classes cannot be applied due to the specificity of another selector. In some cases, a sufficient workaround is to wrap your element’s content in a <code><div></code> or more semantic element with the desired class.</p>
<h2 id="sass">Sass</h2>
<p>In addition to the following Sass functionality, consider reading about our included <a href="/docs/5.1/customize/css-variables/">CSS custom properties</a> (aka CSS variables) for colors and more.</p>
<h3 id="variables">Variables</h3>
<p>Most <code>color</code> utilities are generated by our theme colors, reassigned from our generic color palette variables.</p>
