HTML Iframes
An iframe is used to display a web page within a web page.
Iframe Syntax
An HTML iframe is defined with the <iframe> tag:
<iframe src="URL"></iframe>The src attribute specifies the URL (web address) of the inline frame page.
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:
<iframe src="demo_iframe.htm" height="200" width="300"></iframe>The height and width can also be specified in percent:
<iframe src="demo_iframe.htm" height="100%" width="100%"></iframe>Or you can use CSS to set the height and width of the iframe:
<iframe src="demo_iframe.htm" style="height:200px;width:300px;"></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:
<iframe src="demo_iframe.htm" style="border:none;"></iframe>With CSS, you can also change the size, style and color of the iframe's border:
<iframe src="demo_iframe.htm" style="border:2px solid red;"></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:
<iframe src="demo.html" name="iframe_a"></iframe>
<p><a href="https://www.learncomputer.in" target="iframe_a">Learncomputer.in</a></p>
