Question

How can I make a div or iframe stretch to fill the remaining space using javascript, jQuery, or css?

I'm looking for a way to make the middle iframe dynamically fill the remaining space between two fixed height iframes (one at the top and one at the bottom) regardless of the window screen size. Is there a technique or method that can achieve this? thank you!

for example:

<iframe style="width:100%; height:50px;" src="headerstuff.asp" %></iframe>
<iframe style="width:100%; height:100%;" src="Content.asp" %></iframe>  <!-- height needs to fill -->
<iframe style="width:100%; height:50px;" src="footerstuff.asp" %></iframe>

javascript jquery html css xhtml

Answer №1

If you are dealing with divs, the solution is quite straightforward. Although there may be some uncertainty regarding iframes, your question suggests that divs will suffice:

<div style='background:red; position:absolute; top:0; left:0; right:0; height:50px;'></div>
<div style='background:green; position:absolute; top:50px; left:0; right:0; bottom:50px;'></div>
<div style='background:blue; position:absolute; bottom:0; left:0; right:0; height:50px;'></div>

<iframe id="frame1" style="width:100%; height:50px;" src="topcontent.asp" %></iframe>
<iframe id="frame2" style="width:100%; height:100%;" src="maincontent.asp" %></iframe>  <!-- adjust height dynamically -->
<iframe id="frame3" style="width:100%; height:50px;" src="bottomcontent.asp" %></iframe>

var result, intermediateResult, num1, num2, windowHeight;
num1 = $('#frame1').height(); 
num2 = $('#frame3').height();
windowHeight = $(window).height();
intermediateResult = num1 + num2;
result = windowHeight - intermediateResult;

$('#frame2').height(result);

Here is a possible solution to your query:

To start, adjust the IFRAME's HEIGHT and WIDTH attributes to "100%".

In Internet Explorer 6.0, you have the option to set a % for the height and width of the IFRAME. By setting them to 100%, you instruct the browser to expand the size of the IFRAME to match the dimensions of the IFRAME's immediate parent container; typically the table cell it resides in. (Opting for smaller % values can result in inconsistent white space distribution, leading to an odd appearance when resizing the window.)

Nevertheless, specifying HEIGHT=100% may sometimes cause the IFRAME to occupy only a fraction of the entire window size, as the browser has already determined the size of the containing TD table cell tag. Hence, the challenge lies in prompting the browser to enlarge the enclosing "parent" table cell and table element to fill the browser screen. This goes against the typical behavior of browsers that tend to shrink tables to the minimal size needed to accommodate their content.

As a recap: Adjust your iframe width and height to 100% and ensure that the surrounding containers, divs or table cells adapt to the content as desired. The dimensions of an iframe are relative to the parent container.

To retrieve the dimensions of the browser viewport, you can utilize $(window).height(); and $(window).width();. Then, based on your content, you can adjust the size accordingly.

var mainFrameHeight = $(window).height() - $('iframe #header').height() - $('iframe #footer').height();
$('iframe #content').height(mainFrameHeight);

$('iframe').eq(1).height($(document).height()-100);

My apologies for the oversight of not wrapping window in a jQuery object.

Additionally, please note that this code assumes no borders, margins, etc. on iframes. If your iframes have these properties applied, you will need to account for them in the height calculation or remove them altogether.
