Question/scenario: most css-div based layouts claim to be flexible, elastic, and more elegant than table-based layouts. However, I have not yet found one that is any where near elegant or worth using when you consider the true elasticity of a table. YAML for DNN looks promising.
As a designer, you also have to consider that you are designing a one-size-fits-all template. Most div/css layouts cannot achieve that at all. Generally, if you have a column set to 250px wide and the end user inserts a photo 400px wide, instead of stretching the column and wrapping around this photo, it merely places the photo in column 1 while overlapping the content of column 2. Less than gracefully, too, and your skin/layout is suddenly broken and looks extremely unprofessional.
Yet, a simple table takes care of that problem because a table is truly 100% "elastic". Can the YAML layout function exactly like a table in regards to this issue? The only reason I have refused to design without tables is because, in this respect, div's are just more of a step backwards than they are forwards. Perfect examples are right here at this site in this forum. I see a lot of posts where the text actually gets written over the right side border that is supposed to be the edge of the content. In a professional looking design, regardless of whether it's table or div based, that right hand border had better be able to expand gracefully to wrap around the content placed inside it. I have just not seen any div based layout that can do that. That is, unless your group has discovered the fix? As soon as div/css based layouts actually prove to be more elegant and can truly be elastic, I'll switch over and leave table based design behind, and I'd love it if your template would allow me to do so with a good conscience that I really am providing a client with a DNN skin they will love.
