Full-screen iframe with a height of 100%

Is iframe height=100% supported in all browsers?

I am using doctype as:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
   "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

In my iframe code, if I say:

<iframe src="xyz.pdf" width="100%" height="100%" />

I mean will it actually take the height of the remaining page (as there is another frame on top with fixed height of 50px)
Is this supported in all major browsers (IE/Firefox/Safari) ?

Also regarding scrollbars, even though I say scrolling="no", I can see disabled scrollbars in Firefox…How do I completely hide scrollbars and set the iframe height automatically?

Solution

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!
