would you rate this good CSS design?
For a non-dynamic web site.<br />
I lately found my self using width, min- and max- a lot. and all together. I never read this kind of code. <br />
my question is : `Are there any unseen problems that I can fall into?` <br />
code:<br />

           #page{
    			width:100%;
    			min-width:1200px;
    			max-width:2400px;
    			height:100%;
    			min-height:800px;
    			max-height:1600px;
    		}
    		
    		#left_col{
    			width:20%;
    			min-width:240px;
    			max-width:480px;
    			height:100%;
    			min-height:800px;
    			max-height:1600px;
    			float:left;
    		}
    		
    		#right_col{
    			width:80%;
    			min-width:960px;
    			max-width:1920px;
    			height:100%;
    			min-height:800px;
    			max-height:1600px;
    			float:left;
    		}
    		.cls{clear:both;}
