-title: Making content editable
-slug: Web/Guide/HTML/Editable_content
-translation_of: Web/Guide/HTML/Editable_content
----
-<p><span class="seoSummary">In progress. In HTML, any element can be editable. By using some JavaScript event handlers, you can transform your web page into a full and fast rich text editor. This article provides some information about this functionality.</span></p>
-
-<h2 id="How_does_it_work">How does it work?</h2>
-
-<p>All you have to do is set the {{htmlattrxref("contenteditable")}} attribute on nearly any HTML element to make it editable.</p>
-
-<p>Here's a simple example which creates a {{HTMLElement("div")}} element whose contents the user can edit.</p>
-
-<pre class="brush: html">&lt;div contenteditable="true"&gt;
-  This text can be edited by the user.
-&lt;/div&gt;</pre>
-
-<p>Here's the above HTML in action:</p>
-
-<p>{{ EmbedLiveSample('How_does_it_work') }}</p>
-
-<h2 id="Executing_commands">Executing commands</h2>
-
-<p>When an HTML element has <code>contenteditable</code> set to <code>true</code>, the {{ domxref("document.execCommand()") }} method is made available. This lets you run <a href="/en-US/docs/Web/API/document.execCommand#Commands">commands</a> to manipulate the contents of the editable region. Most commands affect the document's selection by, for example, applying a style to the text (bold, italics, etc), while others insert new elements (like adding a link) or affect an entire line (indenting). When using <code>contentEditable</code>, calling <code>execCommand()</code> will affect the currently active editable element.</p>
-
-<h2 id="Differences_in_markup_generation">Differences in markup generation</h2>
-
-<p>Use of <code>contenteditable</code> across different browsers has been painful for a long time because of the differences in generated markup between browsers. For example, even something as simple as what happens when you press Enter/Return to create a new line of text inside an editable element was handled differently across the major browsers (Firefox inserted {{htmlelement("br")}} elements, IE/Opera used {{htmlelement("p")}}, Chrome/Safari used {{htmlelement("div")}}).</p>
-
-<p>Fortunately, in modern browsers things are somewhat more consistent. As of <a href="/en-US/docs/Mozilla/Firefox/Releases/55">Firefox 55</a>, Firefox has been updated to wrap the separate lines in {{htmlelement("div")}} elements, matching the behavior of Chrome, modern Opera, Edge, and Safari.</p>
-
-<p>Try it out in the above example.</p>
-
-<div class="note">
-<p><strong>Note</strong>: Internet Explorer, which is no longer being developed, uses {{htmlelement("p")}} elements instead of <code>&lt;div&gt;</code>.</p>
-</div>
-
-<p>If you want to use a different paragraph separator, the above browsers all support {{domxref("document.execCommand")}}, which provides a <code>DefaultParagraphSeparator</code> command to allow you to change it. For example, to use {{htmlelement("p")}} elements:</p>
-
-<pre class="language-js"><code class="language-js">document<span class="punctuation token">.</span><span class="function token">execCommand</span><span class="punctuation token">(</span><span class="string token">"DefaultParagraphSeparator"</span><span class="punctuation token">,</span> <span class="keyword token">false</span><span class="punctuation token">,</span> <span class="string token">"p"</span><span class="punctuation token">)</span><span class="punctuation token">;</span></code></pre>
-
-<h2 id="Security">Security</h2>
-
-<p>For security reasons, Firefox doesn't let JavaScript code use clipboard related features (copy, paste, etc.) by default. You can enable them by setting the preferences shown below using <code>about:config</code>:</p>
-
-<pre class="code">user_pref("capability.policy.policynames", "allowclipboard");
-user_pref("capability.policy.allowclipboard.sites", "https://www.mozilla.org");
-user_pref("capability.policy.allowclipboard.Clipboard.cutcopy", "allAccess");
-user_pref("capability.policy.allowclipboard.Clipboard.paste", "allAccess");</pre>
