Determine the Width of a dynamic CSS3 Multicolumn DIV width fixed column-width

Question

I have a DIV container filled with a dynamic text. The length of the text can be different. The DIV container has a fixed height but no width.

Answer 1

Here is the syntax to go about:

var div = document.getElementById(columnWrapper);               
var width = div.css("width"),
var height = div.css("height");
