Random properties pure CSS

Question

I'm just wondering, is it possible to have randomly generated properties using only CSS, or will some javascript be required.

The effect I want to achieve is to have the coloured divs randomly positioned on the page.

HTML:
<div class="box wsbg1"></div>
<div class="box wsbg2"></div>
<div class="box wsbg3"></div>
<div class="box wsbg4"></div>


CSS:
body {
    height: 600px; background-color: #66ccff;}
.box {
    height: 200px; width: 200px; 
    -webkit-transform: rotate(-5deg);
    -moz-transform: rotate(-5deg);
    -webkit-box-shadow: 15px 15px 20px rgba(0, 0, 0, 0.3);
    -moz-box-shadow: 15px 15px 20px rgba(0, 0, 0, 0.3);
}
.wsbg1 {background-color: #ec0689;}
.wsbg2 {background-color: #ffde00;}
.wsbg3 {background-color: #09aeee;}
.wsbg4 {background-color: #5eb345;}

Answer 1

No, CSS is deterministic. Either create randomness with javascript, or serve up a randomly generated css file each time with PHP.

Answer 2

You could do that with CSS pre processors such as LESS or SASS, here is a relevant answer for the same:
