You can use the JavaScript contentWindow property to make an iFrame automatically adjust its height according to the contents inside it, so that no vertical scrollbar will appear.
Using the window. postMessage() method, we can safely communicate between the iframe and the parent window. That way, we can send a height value from the iframe to the parent window. Then, in the parent window, we can set a simple script to dynamically update the height of the iframe.
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!
iframe:In supported browsers, you can use viewport-percentage lengths such as height: 100vh.
Where 100vh represents the height of the viewport, and likewise 100vw 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>This approach is fairly straight-forward. Just set the positioning of the fixed element and add a height/width of 100%.
Example Here
iframe {
position: fixed;
background: #000;
border: none;
top: 0; right: 0;
bottom: 0; left: 0;
width: 100%;
height: 100%;
}<iframe></iframe>For this last method, just set the height of the body/html/iframe elements to 100%.
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>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).
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%; }
This worked very nicely for me (only if iframe content comes from the same domain):
<script type="text/javascript">
function calcHeight(iframeElement){
var the_height= iframeElement.contentWindow.document.body.scrollHeight;
iframeElement.height= the_height;
}
</script>
<iframe src="./page.html" onLoad="calcHeight(this);" frameborder="0" scrolling="no" id="the_iframe" width="100%" ></iframe>
