Module 1:9 HTML - Understanding IFrames

 HTML Iframes

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, which 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:

<iframe src="www.amurchem.com" height="200" width="300" title="Iframe Example"></iframe>

Or you can add the style attribute and use the CSS height and width properties:

<iframe src="www.amurchem.com" 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:

<iframe src="www.amurchem.com" style="border:none;" title="Iframe Example"></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;" 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:

<iframe src="demo_iframe.html" name="iframe_a" title="Iframe Example"></iframe>

<p><a href="https://www.amurchem.com" target="iframe_a">amurchem.com</a></p>

Summary

• The HTML <iframe> tag specifies an inline frame.
• The src attribute defines the URL of the page to embed.
• Always include a title attribute (for screen readers).
• The height and width attributes specify the size of the iframe.
• Use border:none; to remove the border around the iframe.
