CSS adding border radius to an IFrame

Question

Adding a border to an IFrame is no biggie - you do it like this e.g.:

  border: 4px solid #000;
  -moz-border-radius: 15px;
  border-radius: 15px;

The problem is that when you load content to that IFrame, the content overlaps the borders in the corners, like so:

Any ideas how one might get past this issue? E.g. is there a JavaScript library that would take care of this...

Answer 1

I know this is a rather old thread, but I found a valid work around for it that the others didn't cover.

What you're seeing is a z-indexing issue. All you need to do is put your iFrame into a DIV, and set the DIV's and iframe's position to absolute. Then set your z-index in CSS. It works great with Youtube videos in bubbles!

<style>

#player-wrapper{
    border-radius:50%;  
    border:solid 1px #999;
    width:360px;
    height:360px;
    overflow:hidden;
    position:absolute;
    left:50%;
    top:90px;
    margin-left:-130px;
    z-index:10;
}
#player-wrapper iframe{
    position:absolute;
    left:50%;
    margin-left:-320px; 
    z-index:9;
}
</style>

<div id="player-wrapper">
    <iframe id="player" frameborder="0" allowfullscreen="1" title="YouTube video player" width="640" height="360" src="https://www.youtube.com/embed/rTMMraosnzg></iframe>
</div>

Answer 2

You could use the Malsap jQuery rouned corner plugin. It won't fix the actual problem, but it will give you the rounded corners without the issue.

Answer 3

The box-shadow will round corners. Just have a spread-distance of the thickness of your border and a blur value of 0. This is a hack, but what isn't in HTML?

box-shadow: 0 0 0 1px #000;

Will add a 1 pixel border. The first two zeros are the offset. The third zero is how much blur you want to give to the shadow (none). The 1px is how far "out" you want the shadow to go. The last parameter is the color of the border. Most people omit the spread because they want their shadows to be the same size as the element.

Here is an example where I did this, which works in at least IE9 and Chrome 17: http://www.philihp.com/blog/2012/i-made-a-gps-locator-for-myself/
