<p><strong>CodeMirror</strong> is a versatile text editor
implemented in JavaScript for the browser. It is specialized for
editing code, and comes with a number of language modes and addons
that implement more advanced editing functionality.</p>
<p>A rich <a href="doc/manual.html#api">programming API</a> and a
CSS <a href="doc/manual.html#styling">theming</a> system are
available for customizing CodeMirror to fit your application, and
extending it with new functionality.</p>

<h2>Browser support</h2>
<p>The <em>desktop</em> versions of the following browsers,
in <em>standards mode</em> (HTML5 <code><!doctype html></code>
recommended) are supported:</p>
<table style="margin-bottom: 1em">
<tr><th>Firefox</th><td>version 3 and up</td></tr>
<tr><th>Chrome</th><td>any version</td></tr>
<tr><th>Safari</th><td>version 5.2 and up</td></tr>
<tr><th style="padding-right: 1em;">Internet Explorer</th><td>version 8 and up</td></tr>
<tr><th>Opera</th><td>version 9 and up</td></tr>
</table>
<p>Modern mobile browsers tend to partly work. Bug reports and
patches for mobile support are welcome, but the maintainer does not
have the time or budget to actually work on it himself.</p>
