How to Set Iframe Src Attribute?

To set the src attribute of an iframe element in HTML, you can use the following method:

You can set the src attribute of an iframe element by targeting the iframe element in your HTML code and then setting the src attribute to the URL of the web page or content you want to display within the iframe. This can be done using JavaScript or by directly adding the URL as the value of the src attribute in the HTML code.

For example, you can use JavaScript to dynamically set the src attribute of an iframe element like this:

1
2

var iframe = document.getElementById('myIframe');
iframe.src = 'https://www.example.com';

Alternatively, you can set the src attribute directly in the HTML code like this:

1

<iframe src="https://www.example.com"></iframe>

By setting the src attribute of an iframe element, you can display external content within the iframe on your web page.

How to make an iframe responsive?

To make an iframe responsive, you can use CSS media queries to adjust the size of the iframe based on the screen size. Here is a simple example:

1. Add a CSS class to the iframe element:

1

<iframe class="responsive-iframe" src="example.com"></iframe>

1. Add the following CSS code to your stylesheet:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10

.responsive-iframe {
  width: 100%;
  height: 100%;
}

@media (max-width: 768px) {
  .responsive-iframe {
    height: 300px;
  }
}

In this example, the iframe will take up 100% of the width and height of its container by default. When the screen size is reduced to 768px or less, the height of the iframe will be set to 300px to ensure that it remains responsive.

You can adjust the CSS properties in the media query to suit your specific layout requirements.

What is the default value of the src attribute in an iframe?

The default value of the src attribute in an iframe is an empty string.

How to set the width and height attributes of an iframe?

To set the width and height attributes of an iframe, you can use the following HTML code:

1

<iframe src="https://www.example.com" width="500" height="300"></iframe>

In this code snippet, the width attribute sets the width of the iframe to 500 pixels and the height attribute sets the height of the iframe to 300 pixels. You can adjust the values of these attributes to customize the dimensions of the iframe as needed.

How to prevent users from being able to change the src attribute of an iframe?

One way to prevent users from changing the src attribute of an iframe is by using the sandbox attribute. The sandbox attribute allows you to restrict the capabilities of the iframe, including preventing the ability to navigate to a different URL.

You can add the sandbox attribute to the iframe tag like this:

1

<iframe src="https://example.com" sandbox=""></iframe>

By setting the sandbox attribute without any values, you prevent the iframe from being able to navigate to a different URL. This will prevent users from being able to change the src attribute of the iframe.

Additionally, you can also use JavaScript to dynamically set the src attribute of the iframe and prevent users from being able to modify it directly in the HTML code. By setting the src attribute using JavaScript, you can control what URL the iframe loads and prevent users from changing it.
