<h2 id="overview">Overview</h2>
<p>Things to know when using the tooltip plugin:</p>
<ul>
<li>Tooltips rely on the 3rd party library <a href="https://popper.js.org">Popper.js</a> for positioning. You must include <a href="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.11.0/umd/popper.min.js">popper.min.js</a> before bootstrap.js in order for tooltips to work!</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 <code class="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 <code class="highlighter-rouge">.disabled</code> or <code class="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 <code class="highlighter-rouge">white-space: nowrap;</code> on your <code class="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>
<h2 id="example-enable-tooltips-everywhere">Example: Enable tooltips everywhere</h2>
<p>One way to initialize all tooltips on a page would be to select them by their <code class="highlighter-rouge">data-toggle</code> attribute:</p>
<figure class="highlight"><pre><code class="language-js" data-lang="js"><span class="nx">$</span><span class="p">(</span><span class="kd">function</span> <span class="p">()</span> <span class="p">{</span>
<span class="nx">$</span><span class="p">(</span><span class="s1">'[data-toggle="tooltip"]'</span><span class="p">).</span><span class="nx">tooltip</span><span class="p">()</span>
<span class="p">})</span></code></pre></figure>

Tooltip with HTML
<span class="nt"></button></span></code></pre></figure>
<h2 id="usage">Usage</h2>
<p>The tooltip plugin generates content and markup on demand, and by default places tooltips after their trigger element.</p>
<p>Trigger the tooltip via JavaScript:</p>
<figure class="highlight"><pre><code class="language-js" data-lang="js"><span class="nx">$</span><span class="p">(</span><span class="s1">'#example'</span><span class="p">).</span><span class="nx">tooltip</span><span class="p">(</span><span class="nx">options</span><span class="p">)</span></code></pre></figure>
<h3 id="markup">Markup</h3>
<p>The required markup for a tooltip is only a <code class="highlighter-rouge">data</code> attribute and <code class="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 <code class="highlighter-rouge">top</code> by the plugin).</p>
<div class="bd-callout bd-callout-warning">
<h4 id="making-tooltips-work-for-keyboard-and-assistive-technology-users">Making tooltips work for keyboard and assistive technology users</h4>
<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 <code class="highlighter-rouge"><span></code>s) can be made focusable by adding the <code class="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>
</div>
<figure class="highlight"><pre><code class="language-html" data-lang="html"><span class="c"><!-- HTML to write --></span>
<span class="nt"><a</span> <span class="na">href=</span><span class="s">"#"</span> <span class="na">data-toggle=</span><span class="s">"tooltip"</span> <span class="na">title=</span><span class="s">"Some tooltip text!"</span><span class="nt">></span>Hover over me<span class="nt"></a></span>
<span class="c"><!-- Generated markup by the plugin --></span>

<h3 id="options">Options</h3>
<p>Options can be passed via data attributes or JavaScript. For data attributes, append the option name to <code class="highlighter-rouge">data-</code>, as in <code class="highlighter-rouge">data-animation=""</code>.</p>
