I have not done much web design previously and wanted to get an understanding of full-width layouts and responsive design.
Specifically, my question is this - is it considered bad practice to use full-width layouts? I have google'd, and a lot of the feedback is to avoid full width (sticking to the standard 960px width) - however, a lot of the articles I have read were a few years old.
I was thinking about a design for a site that uses full width, using Twitter bootstrap (obviously TB provides the mechanism to go full width, which makes me think it may not be all bad?) - With the TB layout system and responsive design settings, are the drawbacks of using full-width layout as significant?
I have also read about the optimal number of characters per-line issue, that would obviously effect a single column (or even two-column) full width layout - but I was planning to have a full-width three column design. Have people got around this issue?
