Hi,
I have this block of css code:
Code:
/* Smartphones (portrait) ----------- */
@media only screen 
and (max-width : 320px) {
	.feature img {
		width: 250px;
		height: 125px;
	}
	.new_feature img {
		width: 300px;
		height: 150px;
	}
}

/* iPads (portrait and landscape) ----------- */
@media only screen 
and (min-device-width : 768px) 
and (max-device-width : 1024px) {
	.feature img {
		width: 500px;
		height: 250px;
	}
	.new_feature img {
		width: 600px;
		height: 300px;
	}
}
And I access them with this JavaScript function to allow user change classes on the fly:
Code:
function getCssProperty(elmId, property){
   var elem = document.getElementById(elmId);
   return window.getComputedStyle(elem,null).getPropertyValue(property);
}
// get css class value
var width = getCssProperty("my-div", "width");
var height = getCssProperty("my-div", "height");
I'm asking this because I can't afford more than one computer to test my app at the time. And since it is under development, I can't afford to test on online tools either.

Thank you,
