iframe width cannot be controled ?

[mynameisyohann]

hi guys,

I am trying to make some iframes fit into a div with variable width. The iframe must have a margin, and using a padding in the parent div element is not an option.

Unfortunately, the width:auto for iframe gives a preset width, and does not behave like for the div elements.

As a result, the iframe always seem to resize its container.

See the testcases below :

This is how it behaves when a div contains a div with width:auto > that's the result I want to achieve with an iframe
<div style="width:10 0px;background-color:blue">Con tainer<div style="width:au to;margin:10px; background-color:white">co ntent</div></div>

This is how it behaves when a div contains an iframe with width:auto
<div style="width:10 0px;background-color:red">Cont ainer<iframe style="width:au to;margin:10px" src=""></iframe></div>

This is how it behaves when a div contains an iframe with width:100% (the container becomes too big)
<div style="width:10 0px;background-color:red">Cont ainer<iframe style="width:10 0%;margin:10px" src=""></iframe></div>

Any ideas ?
Thanks,

Yohann

may I ask why you need to use iFrame? maybe there's a different solution?

I tried, but could not get a CSS solution.

You may find this useful:

window.onload = function () {
    var ifm = document.getElementsByTagName('iframe')[0];
    ifm.style.width = ifm.parentNode.style.width;
}
