<li>Tooltips rely on the 3rd party library <ahref="https://popper.js.org/">Popper.js</a> for positioning. You must include <ahref="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.14.3/umd/popper.min.js">popper.min.js</a> before bootstrap.js or use <codeclass="highlighter-rouge">bootstrap.bundle.min.js</code> / <codeclass="highlighter-rouge">bootstrap.bundle.js</code> which contains Popper.js in order for tooltips to work!</li>
<li>If you’re building our JavaScript from source, it <ahref="/docs/4.1/getting-started/javascript/#util">requires <codeclass="highlighter-rouge">util.js</code></a>.</li>
<li>Tooltips are opt-in for performance reasons, so <strong>you must initialize them yourself</strong>.</li>
<li>Tooltips with zero-length titles are never displayed.</li>
<li>Specify <codeclass="highlighter-rouge">container: 'body'</code> to avoid rendering problems in more complex components (like our input groups, button groups, etc).</li>
<li>Triggering tooltips on hidden elements will not work.</li>
<li>Tooltips for <codeclass="highlighter-rouge">.disabled</code> or <codeclass="highlighter-rouge">disabled</code> elements must be triggered on a wrapper element.</li>
<li>When triggered from hyperlinks that span multiple lines, tooltips will be centered. Use <codeclass="highlighter-rouge">white-space: nowrap;</code> on your <codeclass="highlighter-rouge"><a></code>s to avoid this behavior.</li>
<li>Tooltips must be hidden before their corresponding elements have been removed from the DOM.</li>
</ul>
<p>Got all that? Great, let’s see how they work with some examples.</p>
<p>Hover over the links below to see tooltips:</p>

<p>The required markup for a tooltip is only a <codeclass="highlighter-rouge">data</code> attribute and <codeclass="highlighter-rouge">title</code> on the HTML element you wish to have a tooltip. The generated markup of a tooltip is rather simple, though it does require a position (by default, set to <codeclass="highlighter-rouge">top</code> by the plugin).</p>
<divclass="bd-callout bd-callout-warning">
<h5id="making-tooltips-work-for-keyboard-and-assistive-technology-users">Making tooltips work for keyboard and assistive technology users</h5>
<p>You should only add tooltips to HTML elements that are traditionally keyboard-focusable and interactive (such as links or form controls). Although arbitrary HTML elements (such as <codeclass="highlighter-rouge"><span></code>s) can be made focusable by adding the <codeclass="highlighter-rouge">tabindex="0"</code> attribute, this will add potentially annoying and confusing tab stops on non-interactive elements for keyboard users. In addition, most assistive technologies currently do not announce the tooltip in this situation.</p>
<p>Additionally, do not rely solely on <codeclass="highlighter-rouge">hover</code> as the trigger for your tooltip, as this will make your tooltips impossible to trigger for keyboard users.</p>
</div>
<figureclass="highlight"><pre><codeclass="language-html"data-lang="html"><spanclass="c"><!-- HTML to write --></span>
<spanclass="nt"><a</span><spanclass="na">href=</span><spanclass="s">"#"</span><spanclass="na">data-toggle=</span><spanclass="s">"tooltip"</span><spanclass="na">title=</span><spanclass="s">"Some tooltip text!"</span><spanclass="nt">></span>Hover over me<spanclass="nt"></a></span>
<spanclass="c"><!-- Generated markup by the plugin --></span>
<p>Elements with the <codeclass="highlighter-rouge">disabled</code> attribute aren’t interactive, meaning users cannot focus, hover, or click them to trigger a tooltip (or popover). As a workaround, you’ll want to trigger the tooltip from a wrapper <codeclass="highlighter-rouge"><div></code> or <codeclass="highlighter-rouge"><span></code>, ideally made keyboard-focusable using <codeclass="highlighter-rouge">tabindex="0"</code>, and override the <codeclass="highlighter-rouge">pointer-events</code> on the disabled element.</p>
<p>Options can be passed via data attributes or JavaScript. For data attributes, append the option name to <codeclass="highlighter-rouge">data-</code>, as in <codeclass="highlighter-rouge">data-animation=""</code>.</p>

<p>Reveals an element’s tooltip. <strong>Returns to the caller before the tooltip has actually been shown</strong> (i.e. before the <codeclass="highlighter-rouge">shown.bs.tooltip</code> event occurs). This is considered a “manual” triggering of the tooltip. Tooltips with zero-length titles are never displayed.</p>
<p>Hides an element’s tooltip. <strong>Returns to the caller before the tooltip has actually been hidden</strong> (i.e. before the <codeclass="highlighter-rouge">hidden.bs.tooltip</code> event occurs). This is considered a “manual” triggering of the tooltip.</p>
<p>Toggles an element’s tooltip. <strong>Returns to the caller before the tooltip has actually been shown or hidden</strong> (i.e. before the <codeclass="highlighter-rouge">shown.bs.tooltip</code> or <codeclass="highlighter-rouge">hidden.bs.tooltip</code> event occurs). This is considered a “manual” triggering of the tooltip.</p>
<p>Hides and destroys an element’s tooltip. Tooltips that use delegation (which are created using <ahref="#options">the <codeclass="highlighter-rouge">selector</code> option</a>) cannot be individually destroyed on descendant trigger elements.</p>
