Description: In making the move to responsive web design, one of the potential hurdles is the rather awkward maths for calculating the percentage-based widths necessary for fluid layouts. If, for example, you’re designing with a 960px grid in Photoshop and you have six columns, each 140px wide, you divide 140 by 960 to get your percentage-based width: 14.583333%. Now, I don’t know about you, but numbers like that look a little scary. It doesn’t matter that there are great calculation tools built into TextMate to do the maths for you; the point is that the final figure looks like an arbitrary number with no immediate relation to either the container’s pixel width (960) or the element’s pixel width (140).
