+ <dd>Applies extra restrictions to the content in the frame. The value of the attribute can either be empty to apply all restrictions, or space-separated tokens to lift particular restrictions:
+ <ul>
+  <li><code>allow-downloads-without-user-activation</code> {{experimental_inline}}: Allows for downloads to occur without a gesture from the user.</li>
+  <li><code>allow-downloads</code>: Allows for downloads to occur with a gesture from the user.</li>
+  <li><code>allow-forms</code>: Allows the resource to submit forms. If this keyword is not used, form submission is blocked.</li>

+  <li><code>allow-popups-to-escape-sandbox</code>: Lets the sandboxed document open new windows without those windows inheriting the sandboxing. For example, this can safely sandbox an advertisement without forcing the same restrictions upon the page the ad links to.</li>
+  <li><code>allow-presentation</code>: Lets the resource start a <a href="/en-US/docs/Web/API/PresentationRequest">presentation session</a>.</li>
+  <li><code>allow-same-origin</code>: If this token is not used, the resource is treated as being from a special origin that always fails the {{Glossary("same-origin policy")}}.</li>
+  <li><code>allow-scripts</code>: Lets the resource run scripts (but not create popup windows).</li>
+  <li><code>allow-storage-access-by-user-activation</code> {{experimental_inline}}: Lets the resource request access to the parent's storage capabilities with the <a href="/en-US/docs/Web/API/Storage_Access_API">Storage Access API</a>.</li>
+  <li><code>allow-top-navigation</code>: Lets the resource navigate the top-level browsing context (the one named <code>_top</code>).</li>

+
+ <ul>
+  <li>When the embedded document has the same origin as the embedding page, it is <strong>strongly discouraged</strong> to use both <code>allow-scripts</code> and <code>allow-same-origin</code>, as that lets the embedded document remove the <code>sandbox</code> attribute — making it no more secure than not using the <code>sandbox</code> attribute at all.</li>
+  <li>Sandboxing is useless if the attacker can display content outside a sandboxed <code>iframe</code> — such as if the viewer opens the frame in a new tab. Such content should be also served from a <em>separate origin</em> to limit potential damage.</li>
+  <li>The <code>sandbox</code> attribute is unsupported in Internet Explorer 9 and earlier.</li>
+ </ul>
+ </div>
+ </dd>
+ <dt>{{htmlattrdef("src")}}</dt>
+ <dd>The URL of the page to embed. Use a value of <code>about:blank</code> to embed an empty page that conforms to the <a href="/en-US/docs/Web/Security/Same-origin_policy#Inherited_origins">same-origin policy</a>. Also note that programatically removing an <code>&lt;iframe&gt;</code>'s src attribute (e.g. via {{domxref("Element.removeAttribute()")}}) causes <code>about:blank</code> to be loaded in the frame in Firefox (from version 65), Chromium-based browsers, and Safari/iOS.</dd>
+ <dt>{{htmlattrdef("srcdoc")}}</dt>
+ <dd>Inline HTML to embed, overriding the <code>src</code> attribute. If a browser does not support the <code>srcdoc</code> attribute, it will fall back to the URL in the <code>src</code> attribute.</dd>
+ <dt>{{htmlattrdef("width")}}</dt>
+ <dd>The width of the frame in CSS pixels. Default is <code>300</code>.</dd>

+ <dd>The alignment of this element with respect to the surrounding context.</dd>
+ <dt>{{htmlattrdef("frameborder")}} {{deprecated_inline}}</dt>
+ <dd>The value <code>1</code> (the default) draws a border around this frame. The value <code>0</code> removes the border around this frame, but you should instead use the CSS property {{cssxref("border")}} to control <code>&lt;iframe&gt;</code> borders.</dd>
+ <dt>{{htmlattrdef("longdesc")}} {{deprecated_inline}}</dt>
+ <dd>A URL of a long description of the frame's content. Due to widespread misuse, this is not helpful for non-visual browsers.</dd>

+<h2 id="Scripting">Scripting</h2>
+
+<p>Inline frames, like {{HTMLElement("frame")}} elements, are included in the {{domxref("window.frames")}} pseudo-array.</p>
+
+<p>With the DOM {{domxref("HTMLIFrameElement")}} object, scripts can access the {{domxref("window")}} object of the framed resource via the {{domxref("HTMLIFrameElement.contentWindow", "contentWindow")}} property. The {{domxref("HTMLIFrameElement.contentDocument", "contentDocument")}} property refers to the <code>document</code> inside the <code>&lt;iframe&gt;</code>, same as <code>contentWindow.document</code>.</p>
+
+<p>From the inside of a frame, a script can get a reference to its parent window with {{domxref("window.parent")}}.</p>
+
+<p>Script access to a frame's content is subject to the <a href="/en-US/docs/Web/Security/Same-origin_policy">same-origin policy</a>. Scripts cannot access most properties in other <code>window</code> objects if the script was loaded from a different origin, including scripts inside a frame accessing the frame's parent. Cross-origin communication can be achieved using {{domxref("Window.postMessage()")}}.</p>
+
+<h2 id="Positioning_and_scaling">Positioning and scaling</h2>
+
+<p>As a <a href="/en-US/docs/Web/CSS/Replaced_element">replaced element</a>, the position, alignment, and scaling of the embedded document within the <code>&lt;iframe&gt;</code> element's box, can be adjusted with the {{cssxref("object-position")}} and {{cssxref("object-fit")}} properties.</p>

+<h2 id="Examples">Examples</h2>
+
+<h3 id="Example1" name="Example1">A simple &lt;iframe&gt;</h3>

+<p>{{EmbedLiveSample('Example1', 640,400)}}</p>
+
+<h2 id="Accessibility_concerns">Accessibility concerns</h2>
+
+<p>People navigating with assistive technology such as a screen reader can use the <a href="/en-US/docs/Web/HTML/Global_attributes/title"><code>title</code> attribute</a> on an <code>&lt;iframe&gt;</code> to label its content. The title's value should concisely describe the embedded content:</p>
+
+<div id="htmlOutputWrapper">
+<pre class="brush: html notranslate">&lt;iframe title="Wikipedia page for Avocados" src="https://en.wikipedia.org/wiki/Avocado"&gt;&lt;/iframe&gt;</pre>
+</div>
+
+<p>Without this title, they have to navigate into the <code>&lt;iframe&gt;</code> to determine what its embedded content is. This context shift can be confusing and time-consuming, especially for pages with multiple <code>&lt;iframe&gt;</code>s and/or if embeds contain interactive content like video or audio.</p>
