+

+
+<p>Bootstrap is maintained by a <a href="https://github.com/orgs/twbs/people">small team of developers</a> on GitHub. We’re actively looking to grow this team and would love to hear from you if you’re excited about CSS at scale, writing and maintaining vanilla JavaScript plugins, and improving build tooling processes for frontend code.</p>
+
+<h2 id="history">History</h2>
+
+<p>Originally created by a designer and a developer at Twitter, Bootstrap has become one of the most popular front-end frameworks and open source projects in the world.</p>
+
+<p>Bootstrap was created at Twitter in mid-2010 by <a href="https://twitter.com/mdo">@mdo</a> and <a href="https://twitter.com/fat">@fat</a>. Prior to being an open-sourced framework, Bootstrap was known as <em>Twitter Blueprint</em>. A few months into development, Twitter held its <a href="https://blog.twitter.com/2010/hack-week">first Hack Week</a> and the project exploded as developers of all skill levels jumped in without any external guidance. It served as the style guide for internal tools development at the company for over a year before its public release, and continues to do so today.</p>
+
+<p>Originally <a href="https://blog.twitter.com/2011/bootstrap-from-twitter">released</a> on <a href="https://twitter.com/mdo/statuses/104620039650557952"><time datetime="2011-08-19 11:25">Friday, August 19, 2011</time></a>, we’ve since had over <a href="https://github.com/twbs/bootstrap/releases">twenty releases</a>, including two major rewrites with v2 and v3. With Bootstrap 2, we added responsive functionality to the entire framework as an optional stylesheet. Building on that with Bootstrap 3, we rewrote the library once more to make it responsive by default with a mobile first approach.</p>
+
+<p>With Bootstrap 4, we once again rewrote the project to account for two key architectural changes: a migration to Sass and the move to CSS’s flexbox. Our intention is to help in a small way to move the web development community forward by pushing for newer CSS properties, fewer dependencies, and new technologies across more modern browsers.</p>

Add <code class="highlighter-rouge">data-toggle="buttons"</code> to a <code class="highlighter-rouge">.btn-group</code> containing those modified buttons to enable their toggling behavior via JavaScript and add <code class="highlighter-rouge">.btn-group-toggle</code> to style the <code class="highlighter-rouge">&lt;input&gt;</code>s within your buttons.</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>Additionally, if your control element is targeting a single collapsible element – i.e. the <code class="highlighter-rouge">data-target</code> attribute is pointing to an <code class="highlighter-rouge">id</code> selector – you may add an additional <code class="highlighter-rouge">aria-controls</code> attribute to the control element, containing the <code class="highlighter-rouge">id</code> of the collapsible element.

Note that if you’re using <code class="highlighter-rouge">&lt;nav&gt;</code>, you shouldn’t add <code class="highlighter-rouge">role="tablist"</code> directly to it, as this would override the element’s native role as a navigation landmark.

 <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">&lt;span&gt;</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>
