I don’t know much about CSS (Cascading Style Sheets), but I know enough to support them strongly, both at work (where it matters) and here (where I just grabbed a default theme, but made sure it employed CSS). Maybe after I get through all the lessons (great stuff, with solid, interactive examples) and start coding myself, the idea of making my CSS more efficient will be useful. I’ll save the link until then. In the meantime, here’s a post about fixed vs. liquid designs, in CSS and otherwise, by a design/interface expert (Doug Bowman), with interesting comments.
