<div class="bd-callout bd-callout-warning">
<h4 id="conveying-meaning-to-assistive-technologies">Conveying meaning to assistive technologies</h4>
<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 class="highlighter-rouge">.sr-only</code> class.</p>
</div>
<h2 id="button-tags">Button tags</h2>
<p>The <code class="highlighter-rouge">.btn</code> classes are designed to be used with the <code class="highlighter-rouge">&lt;button&gt;</code> element. However, you can also use these classes on <code class="highlighter-rouge">&lt;a&gt;</code> or <code class="highlighter-rouge">&lt;input&gt;</code> elements (though some browsers may apply a slightly different rendering).</p>
<p>When using button classes on <code class="highlighter-rouge">&lt;a&gt;</code> elements that are used to trigger in-page functionality (like collapsing content), rather than linking to new pages or sections within the current page, these links should be given a <code class="highlighter-rouge">role="button"</code> to appropriately convey their purpose to assistive technologies such as screen readers.</p>

<h2 id="active-state">Active state</h2>
<p>Buttons will appear pressed (with a darker background, darker border, and inset shadow) when active. <strong>There’s no need to add a class to <code class="highlighter-rouge">&lt;button&gt;</code>s as they use a pseudo-class</strong>. However, you can still force the same active appearance with <code class="highlighter-rouge">.active</code> (and include the <code>aria-pressed="true"</code> attribute) should you need to replicate the state programmatically.</p>
<div class="bd-example" data-example-id="">
<a href="#" class="btn btn-primary btn-lg active" role="button" aria-pressed="true">Primary link</a>
<a href="#" class="btn btn-secondary btn-lg active" role="button" aria-pressed="true">Link</a>

<h2 id="disabled-state">Disabled state</h2>
<p>Make buttons look inactive by adding the <code class="highlighter-rouge">disabled</code> boolean attribute to any <code class="highlighter-rouge">&lt;button&gt;</code> element.</p>
<div class="bd-example" data-example-id="">
<button type="button" class="btn btn-lg btn-primary" disabled="">Primary button</button>
<button type="button" class="btn btn-secondary btn-lg" disabled="">Button</button>
</div>
<div class="highlight"><pre><code class="language-html" data-lang="html"><span class="nt">&lt;button</span> <span class="na">type=</span><span class="s">"button"</span> <span class="na">class=</span><span class="s">"btn btn-lg btn-primary"</span> <span class="na">disabled</span><span class="nt">&gt;</span>Primary button<span class="nt">&lt;/button&gt;</span>
<span class="nt">&lt;button</span> <span class="na">type=</span><span class="s">"button"</span> <span class="na">class=</span><span class="s">"btn btn-secondary btn-lg"</span> <span class="na">disabled</span><span class="nt">&gt;</span>Button<span class="nt">&lt;/button&gt;</span></code></pre></div>
<p>Disabled buttons using the <code class="highlighter-rouge">&lt;a&gt;</code> element behave a bit different:</p>
<ul>
<li><code class="highlighter-rouge">&lt;a&gt;</code>s don’t support the <code class="highlighter-rouge">disabled</code> attribute, so you must add the <code class="highlighter-rouge">.disabled</code> class to make it visually appear disabled.</li>
<li>Some future-friendly styles are included to disable all <code class="highlighter-rouge">pointer-events</code> on anchor buttons. In browsers which support that property, you won’t see the disabled cursor at all.</li>
<li>Disabled buttons should include the <code class="highlighter-rouge">aria-disabled="true"</code> attribute to indicate the state of the element to assistive technologies.</li>
</ul>
<div class="bd-example" data-example-id="">
<a href="#" class="btn btn-primary btn-lg disabled" role="button" aria-disabled="true">Primary link</a>
<a href="#" class="btn btn-secondary btn-lg disabled" role="button" aria-disabled="true">Link</a>

<div class="bd-callout bd-callout-warning">
<h4 id="link-functionality-caveat">Link functionality caveat</h4>
<p>The <code class="highlighter-rouge">.disabled</code> class uses <code class="highlighter-rouge">pointer-events: none</code> to try to disable the link functionality of <code class="highlighter-rouge">&lt;a&gt;</code>s, but that CSS property is not yet standardized. In addition, even in browsers that do support <code class="highlighter-rouge">pointer-events: none</code>, keyboard navigation remains unaffected, meaning that sighted keyboard users and users of assistive technologies will still be able to activate these links. So to be safe, add a <code class="highlighter-rouge">tabindex="-1"</code> attribute on these links (to prevent them from receiving keyboard focus) and use custom JavaScript to disable their functionality.</p>

<p>Do more with buttons. Control button states or create groups of buttons for more components like toolbars.</p>
<h3 id="toggle-states">Toggle states</h3>
<p>Add <code class="highlighter-rouge">data-toggle="button"</code> to toggle a button’s <code class="highlighter-rouge">active</code> state. If you’re pre-toggling a button, you must manually add the <code class="highlighter-rouge">.active</code> class <strong>and</strong> <code class="highlighter-rouge">aria-pressed="true"</code> to the <code class="highlighter-rouge">&lt;button&gt;</code>.</p>

<h3 id="checkbox-and-radio-buttons">Checkbox and radio buttons</h3>
<p>Bootstrap’s <code class="highlighter-rouge">.button</code> styles can be applied to other elements, such as <code class="highlighter-rouge">&lt;label&gt;</code>s, to provide checkbox or radio style button toggling. Add <code class="highlighter-rouge">data-toggle="buttons"</code> to a <code class="highlighter-rouge">.btn-group</code> containing those modified buttons to enable toggling in their respective styles.</p>
<p>The checked state for these buttons is <strong>only updated via <code class="highlighter-rouge">click</code> event</strong> on the button. If you use another method to update the input—e.g., with <code class="highlighter-rouge">&lt;input type="reset"&gt;</code> or by manually applying the input’s <code class="highlighter-rouge">checked</code> property—you’ll need to toggle <code class="highlighter-rouge">.active</code> on the <code class="highlighter-rouge">&lt;label&gt;</code> manually.</p>
<p>Note that pre-checked buttons require you to manually add the <code class="highlighter-rouge">.active</code> class to the input’s <code class="highlighter-rouge">&lt;label&gt;</code>.</p>
