SVN always advocate designing directly in HTML/CSS rather than creating Photoshop mock-ups of page layouts first. They view working in Photoshop as a redundant activity that does not really advance the design process. Rather, it adds an unnecessary intermediate stage that disrupts the main goal of any project which is getting to the final built website. This is a pretty contentious viewpoint as it presupposes that all web designers should be technically proficient in HTML/CSS, which of course they aren’t.
While it makes sense that web designers should understand the scope of and limitations of HTML/CSS and be aware of the main issues such as cross-browser consistency etc, there are many designers who wouldn’t be able to build sample page layouts without some technical support. Additionally, the other main drawback of this stance, is that it puts the tool before the design. Effectively the tool is dictating the nature of the design. Designers should be free to work out a design first and to then figure out (with assistance if required) how to build it with whatever subsequent modifications or compromises that are required.
Good design examples are hard to find on the web, and the few exemplary sites in existence (subtraction or l2m3) really push the boat out in terms of CSS typographic specification. However, these sites clearly evidence an attention to typographic detail that is painstakingly implemented. Good design and typography on the web takes time and effort and it is not merely a functional activity where usability outranks aesthetic considerations as perhaps SVN and the school of Jakob Nielsen suggest. If it did, the web would become a very dull place where ideas and creativity were subservient to rationality and function. A healthy balance is surely always a good thing.
If creative effort isn’t enabled, the space for innovation diminishes. Already, popular blog themes (some are very well designed) have become so prevalent and repetitious that it is getting harder for anything different to emerge from the blogosphere or indeed web design in general.
