An HTML iframe is used to display a web page within a web page.
HTML Iframe Syntax
The HTML <iframe> tag specifies an inline frame.
An inline frame is used to embed another document within the current HTML document.
Syntax
<iframe src=”url“ title=”description“></iframe>
Tip: It is a good practice to always include a title attribute for the <iframe>. This is used by screen readers to read out what the content of the iframe is.
Iframe – Set Height and Width
Use the height and width attributes to specify the size of the iframe.
The height and width are specified in pixels by default:
Example
<iframe src=”demo_iframe.htm” height=”200″ width=”300″ title=”Iframe Example”></iframe>
Or you can add the style attribute and use the CSS height and width properties:
Example
<iframe src=”demo_iframe.htm” style=”height:200px;width:300px;” title=”Iframe Example”></iframe>
Iframe – Remove the Border
By default, an iframe has a border around it.
To remove the border, add the style attribute and use the CSS border property:
Example
<iframe src=”demo_iframe.htm” style=”border:none;” title=”Iframe Example”></iframe>
With CSS, you can also change the size, style and color of the iframe’s border:
Example
<iframe src=”demo_iframe.htm” style=”border:2px solid red;” title=”Iframe Example”></iframe>
Iframe – Target for a Link
An iframe can be used as the target frame for a link.
The target attribute of the link must refer to the name attribute of the iframe:
Example
<iframe src=”demo_iframe.htm” name=”iframe_a” title=”Iframe Example”></iframe>
<p><a href=”https://freeguide.in” target=”iframe_a”>freenotes.site</a></p>
