I have a website that has an iframe called on the page that is filled with another website that calls a only-when-viewed-in-an-iframe stylesheet. Would a css file from the main site overwrite styles of the iframe stylesheet for elements in the iframe?
Example:
<html><body><head><link rel="stylesheet" src="style.css" /></head><iframe src="mysite.com"></iframe></body></html>
So would the styles in style.css overwrite the styles set in the stylesheet that is called with mysite.com from the iframe?
