<h2 id="Summary" name="Summary">Summary</h2>
<p>The <strong>HTML <code>&lt;dialog&gt;</code> element</strong> represents a dialog box or other interactive component, such as an inspector or window. <code>&lt;form&gt;</code> elements can be integrated within a dialog by specifying them with the attribute <code>method="dialog"</code>. When such a form is submitted, the dialog is closed with a <code>returnValue</code> attribute set to the <code>value</code> of the submit button used.</p>
<p>The {{cssxref('::backdrop')}} CSS pseudo-element can be used to style behind a <code>&lt;dialog&gt;</code> element, for example to dim inaccessible content whilst a modal dialog is active.</p>
