HTML iframes

HTML Iframe is used to display a nested webpage (a webpage within a webpage). The HTML <iframe> tag defines an inline frame, hence it is also called as an Inline frame.

An HTML iframe embeds another document within the current HTML document in the rectangular region.

The webpage content and iframe contents can interact with each other using JavaScript.

Iframe Syntax

An HTML iframe is defined with the <iframe> tag:

<iframe src="URL"></iframe>

Here, "src" attribute specifies the web address (URL) of the inline frame page.

Set Width and Height of iframe

You can set the width and height of iframe by using "width" and "height" attributes. By default, the attributes values are specified in pixels but you can also set them in percent. i.e. 50%, 60% etc.

Example: (Pixels)

<!DOCTYPE html>  
<html>  
<body>  
<h2>HTML Iframes example</h2>  
<p>Use the height and width attributes to specify the size of the iframe:</p>  
<iframe src="https://www.TheDeveloperBlog.com/" height="300" width="400"></iframe>  
</body>  
</html>

Remove the border of iframe

By default, an iframe contains a border around it. You can remove the border by using <style> attribute and CSS border property.

Example:

<!DOCTYPE html>  
<html>  
<body>  
<h2>Remove the Iframe Border</h2>  
<p>This iframe example doesn't have any border</p>   
<iframe src="https://www.TheDeveloperBlog.com/" style="border:none;"></iframe>  
</body>  
</html>

You can also change the size, color, style of the iframe's border.

Example:

<!DOCTYPE html>  
<html>  
<body>  
<h2>Custom Iframe Border</h2>  
<iframe src="https://www.TheDeveloperBlog.com/" style="border:2px solid tomato;"></iframe>
