Iframes in HTML are nothing but inline frames used as an HTML document to add another HTML document into it. It’s mostly used in web pages or web development processes to include other content through another source like advertisements on that webpage.

Most web designers use Iframe to present interactive applications on the website or web pages. It’s made possible using JavaScript or the target attribute in HTML.

The main purpose of an Iframe is to display a web page within another. The inline frame should be displayed using a tag called . It works like a rectangular block on your web page where the browser can show another document with scrollbars and borders.</p> <p><strong>Syntax</strong></p> <ul> <li>Now we will see how exactly Iframe is going to use:</li> </ul> <div class="code" style="position:relative; padding:0px; margin:0px;"><pre class="brush:php;toolbar:false"><iframe src ="URL"></iframe></pre><div class="contentsignin">Copy after login</div></div> <ul> <li>Here <iframe> is a tag where HTML iframes will be defined. Src attributes that are used to define the URL of the inline frame page will be included.</li> </ul> <p><strong>Example:</strong></p> <div class="code" style="position:relative; padding:0px; margin:0px;"><pre class="brush:php;toolbar:false"><iframe src ="www.educba.com" ></iframe></pre><div class="contentsignin">Copy after login</div></div> <ul> <li>It is also possible to give some specific height and width to our Iframe in pixels format as follows:</li> </ul> <div class="code" style="position:relative; padding:0px; margin:0px;"><pre class="brush:php;toolbar:false"><iframe src ="URL" height="value" width="value"></iframe></pre><div class="contentsignin">Copy after login</div></div> <ul> <li>In the above syntax, all things will be going to same; additionally, we can specify height and width in pixels format, defining them as</li> </ul> <p><strong>Example:</strong></p> <div class="code" style="position:relative; padding:0px; margin:0px;"><pre class="brush:php;toolbar:false"><iframe src ="www.educba.com" height="300" width="300"></iframe></pre><div class="contentsignin">Copy after login</div></div> <ul> <li>One more method for defining the height and width of the iframe by using values through CSS is shown in the syntax below:</li> </ul> <div class="code" style="position:relative; padding:0px; margin:0px;"><pre class="brush:php;toolbar:false"><iframe src ="URL" style="height: value in pixels; width: value in pixels"></iframe></pre><div class="contentsignin">Copy after login</div></div> <ul> <li>All things are the same as above, just doing a change in specifying values.</li> </ul> <p><strong>Example:</strong></p> <div class="code" style="position:relative; padding:0px; margin:0px;"><pre class="brush:php;toolbar:false"><iframe src ="www.educba.com" style="height:300px; width:300px;"></iframe></pre><div class="contentsignin">Copy after login</div></div> <ul> <li>One more feature that gets added to the iframe is we can remove already defined borders to the frame by using border none property. The syntax for this is as follows:</li> </ul> <div class="code" style="position:relative; padding:0px; margin:0px;"><pre class="brush:php;toolbar:false"><iframe src ="URL" style="border : none;"></iframe></pre><div class="contentsignin">Copy after login</div></div> <ul> <li>With the help of CSS, it’s also possible to do many things with the border, like changing its size, applying some color to the border, etc.</li> </ul> <p>The iframe can be used as Target for a link by using the syntax:</p> <div class="code" style="position:relative; padding:0px; margin:0px;"><pre class="brush:php;toolbar:false"><iframe src ="URL" name="iframe_a"></iframe></pre><div class="contentsignin">Copy after login</div></div> <ul> <li>In the above syntax, src is our normal URL; here, the link’s target attribute will refer to the name attribute in our iframe tag.</li> </ul> <p><strong>Example:</strong></p> <div class="code" style="position:relative; padding:0px; margin:0px;"><pre class="brush:php;toolbar:false"><iframe src ="www.educba.com" name="iframe_a"></iframe></pre><div class="contentsignin">Copy after login</div></div> <h3 id="Iframes-Tag-Attribute">Iframes Tag Attribute</h3> <p>There are different attribute tags used in Iframes. Those are as follows:</p> <ul> <li> <strong>Src:</strong> This attribute is used to insert a file that needs to be included in the frame. URL specifies the target webpage to be loaded within an iframe.</li> <li> <strong>Name:</strong> Name is an attribute used to give some identification name to the frame. It’s most useful when you are creating one link to open another webpage.</li> <li> <strong>allowfullscreen:</strong> This attribute allows you to display your frame in the full-width format. So we have to set the value true to happen to this function.</li> <li> <strong>Frameborder:</strong> This is a helpful attribute that allows you to show a border or not to show the border to the frame. Value 1 is to show the border & 0 is not to show the border to the frame.</li> <li> <strong>Marginwidth:</strong> Allows you to define space between the left & right sides of the frame.</li> <li> <strong>Marginheight:</strong> This allows you to define space between the top & bottom of the frame.</li> <li> <strong>Scrolling:</strong> These attributes control whether the scrollbar will show or not in the frame. The values included are ‘yes’, ‘ no,’ or ‘auto.’</li> <li> <strong>Height:</strong> It is used to define the height of the frame. Whether in % or pixels</li> <li> <strong>Width:</strong> It is used to define the width of the frame. Whether in % or pixels</li> <li> <strong>Longdesc:</strong> With the help of this attribute, you can link another page with a lengthy description of the contents of your frame.</li> </ul> <h3 id="Examples-of-Iframes-in-HTML">Examples of Iframes in HTML</h3> <p>Here are some examples of Iframes in HTML, which are explained below:</p> <h4 id="Example">Example #1</h4> <p>Let’s consider one example where we will show how to create an iframe with a specific height and width.</p> <p><strong>Code:</strong></p> <div class="code" style="position:relative; padding:0px; margin:0px;"><pre class="brush:php;toolbar:false"><!DOCTYPE html> <html> <body> <h2>HTML Iframes Demo</h2> <p>Here, we are showing an example of Iframe which containing specific Height and width in pixels format</p> <iframe src="C:\Users\Sonali\Desktop\HTML block elements.html" height="300" width="300"></iframe> </body> </html></pre><div class="contentsignin">Copy after login</div></div> <p><strong>Output:</strong></p> <p><img src="/static/imghw/default1.png" data-src="https://img.php.cn/upload/article/000/000/000/172543929564512.png" class="lazy" alt="Iframes in HTML" ></p> <h4 id="Example">Example #2</h4> <p>Let’s consider another example where we will show how to create an iframe with a specific height and width. But in this example, we are specifying height and width through CSS.
