I'm trying to fully understand when it is a good idea to set a width in %, and when to set it in pixels.
For example, I have a 3 column layout I've done, and I set each column's width as a % (all 3 equaling 73% in total to give some white space). But I also set a min-width of a certain pixel width so they only re-size so much So the Div's don't shrink smaller than such things as images within the Div's. I also had issues before implementing this where if the window was re-sized, the div's would shrink, and one might go underneath the other two instead of staying at it's side. This was my original reason for setting a pixel value to min-width.
Would you say this method is a good idea? Also are there any good guidelines to know when it comes to knowing which value to use for width?
