Full-screen iframe with a height of 100%
3 approaches for creating a fullscreen iframe
:
Approach 1 - Viewport-percentage lengths
In supported browsers, you can use viewport-percentage lengths such as
height: 100vh
.Where
100vh
represents the height of the viewport, and likewise100vw
represents the width.Example Here
body { margin: 0; /* Reset default margin */ } iframe { display: block; /* iframes are inline by default */ background: #000; border: none; /* Reset default border */ height: 100vh; /* Viewport-relative units */ width: 100vw; }
<iframe></iframe>
Approach 2 - Fixed positioning
This approach is fairly straight-forward. Just set the positioning of the
fixed
element and add aheight
/width
of100%
.Example Here
iframe { position: fixed; background: #000; border: none; top: 0; right: 0; bottom: 0; left: 0; width: 100%; height: 100%; }
<iframe></iframe>
Approach 3
For this last method, just set the
height
of thebody
/html
/iframe
elements to100%
.Example Here
html, body { height: 100%; margin: 0; /* Reset default margin on the body element */ } iframe { display: block; /* iframes are inline by default */ background: #000; border: none; /* Reset default border */ width: 100%; height: 100%; }
<iframe></iframe>
1. Change your DOCTYPE to something less strict. Don't use XHTML; it's silly. Just use the HTML 5 doctype and you're good:
<!doctype html>
2. You might need to make sure (depends on the browser) that the iframe's parent has a height. And its parent. And its parent. Etc:
html, body { height: 100%; }
I ran into the same problem, I was pulling an iframe into a div. Try this:
<iframe src="http://stackoverflow.com/" frameborder="0" scrolling="yes" seamless="seamless" style="display:block; width:100%; height:100vh;"></iframe>
The height is set to 100vh which stands for viewport height. Also, the width could be set to 100vw, although you'll likely run into problems if the source file is responsive (your frame will become very wide).
You could use frameset as the previous answer states but if you are insistent on using iFrames, the 2 following examples should work:
<body style="margin:0px;padding:0px;overflow:hidden">
<iframe src="http://www.youraddress.com" frameborder="0" style="overflow:hidden;height:100%;width:100%" height="100%" width="100%"></iframe>
</body>
An alternative:
<body style="margin:0px;padding:0px;overflow:hidden">
<iframe src="http://www.youraddress.com" frameborder="0" style="overflow:hidden;overflow-x:hidden;overflow-y:hidden;height:100%;width:100%;position:absolute;top:0px;left:0px;right:0px;bottom:0px" height="100%" width="100%"></iframe>
</body>
To hide scrolling with 2 alternatives as shown above:
<body style="margin:0px;padding:0px;overflow:hidden">
<iframe src="http://www.youraddress.com" frameborder="0" style="overflow:hidden;height:150%;width:150%" height="150%" width="150%"></iframe>
</body>
Hack with the second example:
<body style="margin:0px;padding:0px;overflow:hidden">
<iframe src="http://www.youraddress.com" frameborder="0" style="overflow:hidden;overflow-x:hidden;overflow-y:hidden;height:150%;width:150%;position:absolute;top:0px;left:0px;right:0px;bottom:0px" height="150%" width="150%"></iframe>
</body>
To hide the scroll-bars of the iFrame, the parent is made overflow: hidden
to hide scrollbars and the iFrame is made to go upto 150% width and height which forces the scroll-bars outside the page and since the body doesn't have scroll-bars one may not expect the iframe to be exceeding the bounds of the page. This hides the scrollbars of the iFrame with full width!
