How to apply CSS to iframe?

We can specify CSS for iframe using inline CSS
<iframe name="iframe1" id="iframe1" src="empty.htm"
frameborder="0" border="0" cellspacing="0"
style="border-style: none;width: 100%; height: 120px;"></iframe>

There are two different things here: the style of the iframe block and the style of the page embedded in the iframe. You can set the style of the iframe block the usual way:

<iframe name="iframe1" id="iframe1" src="empty.htm" 

        frameborder="0" border="0" cellspacing="0"

        style="border-style: none;width: 100%; height: 120px;"></iframe>

The style of the page embedded in the iframe must be either set by including it in the child page:

<link type="text/css" rel="Stylesheet" href="Style/simple.css" />

Or it can be loaded from the parent page with Javascript:

var cssLink = document.createElement("link");

cssLink.href = "style.css"; 

cssLink.rel = "stylesheet"; 

cssLink.type = "text/css"; 

frames['iframe1'].document.head.appendChild(cssLink);
