<p>In order to deliver a consistent and usable cross-browser experience, Bootstrap currently has to work around several outstanding bugs in major browsers. And in some cases, we are completely unable to work around certain bugs, and must instead either document them for the benefit of our users or accept a degraded experience. We publicly list browser bugs that are impacting us here, in the hopes of expediting the process of fixing them. For information on Bootstrap's browser compatibility, <ahref="../getting-started/#support">see our browser compatibility docs</a>.</p>

<p>Unofficially, Bootstrap should look and behave well enough in Chromium and Chrome for Linux, Firefox for Linux, and Internet Explorer 7, though they are not officially supported.</p>
<p>For a list of some of the browser bugs that Bootstrap has to grapple with, see our <ahref="../browser-bugs/">Wall of browser bugs</a>.</p>
<h3id="support-ie8-ie9">Internet Explorer 8 and 9</h3>
<p>Internet Explorer 8 and 9 are also supported, however, please be aware that some CSS3 properties and HTML5 elements are not fully supported by these browsers. In addition, <strong>Internet Explorer 8 requires the use of <ahref="https://github.com/scottjehl/Respond">Respond.js</a> to enable media query support.</strong></p>
