Style Can Be established through Small exercises
Full-page comps were a bear to create, especially if we tried to show multiple pages at 
multiple sizes. Rarely does a footer or ad block inspire the entire direction of a site, so 
why figure out the pixel-perfect details now? Instead, exploration through style tiles, 
style prototypes, and element collages help establish style without needing to define 
such minutiae (see Figure 12.1). Better yet, they help us frame the style of an entire 
system rather than a specific page.
