Iframe 100% Height Inside Body with Padding

Iframe 100% height inside body with padding

Whilst you can't say ‘height: 100% minus some pixels’ in CSS, you can make the iframe 100% high, then push its top down using padding. Then you can take advantage of the CSS3 box-sizing property to make the padding get subtracted from the height.

This:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html><head>
    <title>test</title>
    <style type="text/css">
        html, body { margin: 0; padding: 0; height: 100%; }
        #bar { height: 32px; background: red; }
        iframe {
            position: absolute;
            top: 0; left: 0; width: 100%; height: 100%;
            border: none; padding-top: 32px;
            box-sizing: border-box; -moz-box-sizing: border-box; -webkit-box-sizing: border-box;
        }
    </style>
</head><body>
    <iframe src="http://www.google.com/"></iframe>
    <div id="bar">foo</div>
<body></html>

Works on IE8, Moz, Op, Saf, Chrome. You'd have to carry on using a JavaScript fallback to make the extra scrollbar disappear for browsers that don't support box-sizing though (in particular IE up to 7).

Make Iframe to fit 100% of container's remaining height

Update in 2019

TL;DR: Today the best option is - flexbox. Everything supports it nicely and has for years. Go for that and don't look back. Here is a code sample for flexbox:

body, html {width: 100%; height: 100%; margin: 0; padding: 0}
.row-container {display: flex; width: 100%; height: 100%; flex-direction: column; background-color: blue; overflow: hidden;}
.first-row {background-color: lime; }
.second-row { flex-grow: 1; border: none; margin: 0; padding: 0; }

<div class="row-container">
  <div class="first-row">
    <p>Some text</p>
    <p>And some more text</p>
  </div>
  <iframe src="https://jsfiddle.net/about" class="second-row"></iframe>
</div>

Full-screen iframe with a height of 100%

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!

Height equal to 100% is not working for IFrame

What you want could actually be done by changing the height : 100%; value to height : 100vh;.The vh is a unit called ViewHeight, and your full screen height is actually 100vh;

Here is a post about length units from the Mozilla team.

Try this code :

<div class="col-sm-6" style="margin:0px;padding:0px;overflow:hidden">    <iframe id="iFrame1" src="http://www.stackoverflow.com" frameborder="0" style="overflow:hidden;height:100vh;width:100%; border : 1px solid red;"></iframe></div>

IFRAME Set Height to 100%

Try this out. It worked for me:

<html>
<body style="position:relative;">
    <div style="position:fixed; left:0; right:0; top:0; bottom:0;margin:0px;padding:0px;overflow:hidden">
        <iframe src="https://example.com/" frameborder="0" style="overflow:hidden;height:100%;width:100%" height="100%" width="100%">
        </iframe>
    </div>
</body>
</html>

Iframe embedded with 100% height in a div has strange bottom-margin

Add display:block for your iframe element – without that, it is rendered as an inline box, and therefor space is left for the under-lengths of glyphs like g, p, f etc. of (hypothetical) text that might be displayed on the same line.

See fiddle: http://jsfiddle.net/b5jgn/2/

(vertical-align:bottom for the iframe would also work.)

How do I make an HTML iFrame fit the whole page without needing to scroll?

html,body{
            width:100%;
            height:100vh;
            overflow:hidden;
            margin:0px;
            padding:0px;
            border:none;
        }
        iframe{
            width:100%;
            height:100vh;
            overflow:hidden;
            margin:0px;
            padding:0px;
            border:none;
        }
