The iframe HTML tag embeds a web document into a web page. An embedded document can be a PDF, a web page, or some other resource. The src attribute defines the location of the on-board resource.

You can embed the content of a web document , such as a PDF or a map from Google Maps, on another page, using HTML.

This is where HTML </em> comes in. HTML <em>The <iframe></em> tag is used to embed external objects like other web pages into a single web page. This tutorial will explain, with examples, how to use the HTML <em><iframe></em> tag to embed web resources into a web page.</p> <h2> HTML iframe</h2><p>HTML iframes, or embedded frames, display external web documents on a page. You can embed maps, PDFs, videos, or other resources using the HTML <iframe> tag .</p> <p>The code stored in an inline frame is independent from the rest of a web page. Styles or JavaScript that apply to your web page will not be applied in the iframe.</p> <p>Here is the syntax of the HTML <em><iframe></em> tag: </p> <p>The <em><iframe></em> tag is used to create an iframe. We have specified an iframe <em>src</em> attribute. The attribute contains the position of the HTML elements that we want to embed in our web page. It should be an <a href="/url-vs-uri/"> HTML URL </a>.</p> <h2> Example HTML iframe</h2><p>Let’s take an example to explore how the <em><iframe></em> tag works.</p> </div> </div> <p>Suppose you are building a website for a local historic business in Washington, DC. They want us to create a page with an embedded video from Khan Academy on the birth of the United States Constitution. This page is recommended material for anyone interested in joining the company. We can use the following code to embed the video on our website:</p> <p>Our code returns:</p> </a> </div> < Figure class = "wp-image-block"> <img src = "https://lh5.googleusercontent.com/B7_aNtKMRo5xi-n1RJKv6PbF3jGnedSEMOiboyASj-IdPDUErLGbwsrJ3AvdFby6ubXoc VAlCiuoLIFyDI3MYgvAr0Xv3hofcMHDvGPd8ABgVkWruwAY9tH8jjBB47XWanf" alt = "B7 ANtKMRo5xi N1RJKv6PbF3jGnedSEMOiboyASj IdPDUErLGbwsrJ3AvdFby6ubXocM93gNVAlCiuoLIFyDI3MYgvAr0Xv3hofcMHDvGPd8ABgVkWruwAY9tH8jjBB47XWanf"> </ figure> <p>used an <em><iframe></em> to embed an external web resource to our webpage. The web resource we have built is the link "<a href="https://www.youtube.com/embed/Rk8dCnKIfP4" target="_blank" rel="noopener"> https://www.youtube.com / embed / Rk8dCnKIfP4 </a> ". This indicates the video that the historical society wants to show on its website.</p> <h4> Height and width of the HTML iframe </h4> <p>The height and width attribute are used to define the size of an iframe. Suppose the local Washington DC historical society wants us to enlarge the video on their site.</p> <p>We are going to set the width of the YouTube video to 500 pixels and the height to 300 pixels:</p> <p>p> <p>Our code returns: </p> <figure class = "wp-image-block"> <img src = "https: / / lh4.googleusercontent.com/YBnpQe9nKF00pYzt6ESAsx-siD25fEYpDnVr9lpQVzrNKBy5R2ozOoQbIpJMVfZS08LTMeKp-OTyWrumRMNbT0M0ZmkQrfAKdsXIWkIYJs5d8U3Ih8QRI5u4uYK0CmzTDOT5n0HZ" alt = "YBnpQe9nKF00pYzt6ESAsx SiD25fEYpDnVr9lpQVzrNKBy5R2ozOoQbIpJMVfZS08LTMeKp OTyWrumRMNbT0M0ZmkQrfAKdsXIWkIYJs5d8U3Ih8QRI5u4uYK0CmzTDOT5n0HZ "> </ figure> <p>our embedded video is now 500px wide and 300px high on our HTML document. This makes it easier for people to view our website</p> on the </ figure> <p>website.</p> > Alternatively, we could define the <a href="/css-height-and-width/"> width and the height tor the iframe tag using CSS </a>. However, since HTML supports a height and weight attribute, this is not necessary.</p> <h2> Remove border from HTML iframe</h2><p>When working with <em><iframe> </em>, you notice that its content is surrounded by a border. If you want to remove this border, you can use <a href="/css-borders/"> <em>border: none ;</em> </a> <a href="/css-borders/"> CSS attribute </a>.</p> <p>The historical society has asked us to remove the border around the YouTube video from their site. Here is the code we would use to remove the border:</p> <p>Our code returns: </p> <class face = "wp-image-block"> <img src = "https://lh5.googleusercontent.com/GqIGiI370xPK2xxk-C_lCtJfww6i5MJY_NYNSyKQMUmntzGAJX1b8hojU86mDXRKnt3UKFri1tIvxYrtZ6fJojJboymP3a2CjChs3orcV7A4dfqor8MCJdj9qNNy4QOd3X92kSOF" alt = "C GqIGiI370xPK2xxk LCtJfww6i5MJY NYNSyKQMUmntzGAJX1b8hojU86mDXRKnt3UKFri1tIvxYrtZ6fJojJboymP3a2CjChs3orcV7A4dfqor8MCJdj9qNNy4QOd3X92kSOF"> </ figure> <p>now our video it no longer has a border.</p> <h2> Target of HTML iframe link</h2><p>Additionally, you can use <em><iframe></em> tags as the target frame for a link. We can define an iframe as the target frame for a link using the target attribute in an HTML link. The target HTML attribute must refer to the name attribute of an <em><iframe></em>.</p> <p>Suppose the historical society has another video that they want us to show on their website on Article I of the United States Constitution. This video was also posted by Khan Academy.</p> </a> </div> <p>When you click on the text <em>Birth</em> on the web page, the video <em>Birth of the Constitution of the States- United</em> must appear in the iframe. When the text <em>Article I</em> is clicked, the video on Article I of the Constitution should be rendered.</p> <p>We could use the following code to do this:</p> <p>Our code returns: </p> <figure class = "wp -block-image"> <img src = "https: //lh4.googleusercontent.com/RdKRFkGb8AcQn8T5zIBRCZte8MRcbEjjsS4aQYQF7vZDr3_LXitgw2l3uX8Lq6Y2RcT xyYH5BxOkW4Iy OALB2enMO889lpKqXFXewdFTNji1hOCLhn9tbM2-oJNxlwbz5OLQeqJr" alt = "> < / figure RdKRFkGb8AcQn8T5zIBRCZte8MRcbEjjsS4aQYQF7vZDr3 LXitgw2l3uX8Lq6Y2RcTxyYH5BxOkW4IyOALB2enMO889lpKqXFXewdFTNji1hOCLhn9tbM2 OJNxlwbz5OLQeqJr "> <p>by default, the video on the birth of the Constitution of the United States stated in iframes. the content of the iframe changes to point to the Khan Academy video on Article I of the Constitution. This happens when you click on the <em>Article I</em> URL.</p> </div> <p>Our iframe is redirected to the video on the birth of the Constitution if this video is not already present when we click on <em>Birth</em>.</p> <h2> Conclusion</h2><p>The HTML <em><iframe></em> tag embeds external web resources such as web pages into another web page. This is useful if you want to add maps, files, videos, or other web pages to your site.</p> <p>This tutorial explained, referring to examples, how to use HTML <em><iframe> </em> to display external web resources on a web page.
