HTML Iframes

The HTML <iframe> tag is used to embed a webpage within a webpage. It is also called an inline frame. For example,

<iframe src="" title="programiz pro website" height="500" width="500" ></iframe>

  • src: It is used to specify the URL of the website to be loaded.
  • title: It is good practice to include a title attribute so that screen readers can read the title to users.

Other Attributes for <iframe>

There are some importat attributes for <iframe>. They are:

  • height and width
  • name
  • srcdoc

We will explore each of them in detail.

height and width

We can set the height and width of the <iframe> element with the height or width attribute. For example,

<iframe src="" height="200" width="300"></iframe>

We can also use CSS to set the width and height of the <iframe> using the style attribute. For example,

<iframe src="" style="height:200px;width:300px"></iframe>

It is important to add height and width to allocate space on the webpage for the iframe. It prevents content from moving when the iframe loads.


The name attribute is used to specify the name for an iframe. It can be used as a target for other HTML elements like the <a> tag. For example,

<iframe src="" name="iframe_target" height="500" width="400"></iframe>

<a href="" target="iframe_target">Switch to Programiz Pro</a>

Browser Output (Before Clicking the link)

A website open on an iframe with an anchor which targets the iframe

Browser Output (After clicking the link)

A website open on an iframe with an anchor which targets the iframe

Here, clicking the <a> tag changes the URL of the target instead of the current window.


Instead of a website URL, we can send HTML directly to the iframe, which will be displayed instead of another website. For example,

<iframe srcdoc="<h1>Learn to code</h1>"></iframe>
