Remove border from IFrame

In addition to adding the frameBorder attribute you might want to consider setting the scrolling attribute to "no" to prevent scrollbars from appearing.

<iframe src="myURL" width="300" height="300" frameBorder="0" scrolling="no">Browser not compatible. </iframe > 

As per iframe documentation, frameBorder is deprecated and using the "border" CSS attribute is preferred:

<iframe src="test.html" style="width: 100%; height: 400px; border: 0"></iframe>

• Note CSS border property does not achieve the desired results in IE6, 7 or 8.

After going mad trying to remove the border in IE7, I found that the frameBorder attribute is case sensitive.

You have to set the frameBorder attribute with a capital B.

<iframe frameBorder="0"></iframe>

Add the frameBorder attribute (note the capital ‘B’).

So it would look like:

<iframe src="myURL" width="300" height="300" frameBorder="0">Browser not compatible.</iframe>
