I'm trying a more fluid design.
I want specific divs to be a percentage of the overall body. I also want to set fluid / liquid padding within each div.
<body>
<div class='image'></div>
<div class='fourty'></div>
<div class='sixty'></div>
</body>
CSS:
body {
margin-top: 85px;
min-height: 100%;
}
.image {
content: image_url('something.jpg');
width: 100%;
height: auto;
}
/*I'm assuming the padding I'm setting is a percentage of the .fourty
div not the overall body. Granted, width is 100%.*/
.fourty{
padding: 4% 8%;
min-height: 40%;
width: 100%;
}
.sixty{
padding: 4% 8%;
min-height: 60%;
width: 100%;
}
The problem I'm having is that the percentage height does not seem to take effect for these divs. It seems to just be an auto height based off the contents of the div.
How do I correct / achieve this? I'm open to a JS solution, but would be more interested as to how to accomplish this in CSS.

As far as CSS goes, there are no styles that you can apply to make an element's height equal to a certain percentage of the total document (body) height.
CSS does, however, offer you options to style an element's heights to a certain percentage of the viewport height (using VH units), but since this does not achieve your goal, I'll leave you with a javascript answer that does.
Relevant javascript functions:
function getDocumentHeight() {
return Math.max(document.body.scrollHeight, document.documentElement.scrollHeight, document.body.offsetHeight, document.documentElement.offsetHeight, document.documentElement.clientHeight);
};
function setDivHeight(target, percentage) {
var desiredHeight = getDocumentHeight() * (percentage/100)
target.style.height = desiredHeight + 'px';
};
To set the height initially and on viewport resizes:
var targetDiv = document.getElementById('target');
setDivHeight(targetDiv);
window.addEventListener('resize', setDivHeight.bind(null, targetDiv))
