One of the hardest parts of converting a PSD design into a well structured and semantic CSS/HTML layout is first knowing where to start. Although that may sound simplistic and obvious, it really does matter how you begin and that you build on strong foundations to start with. In this series of articles I will take you step by step through the conversion process and look at decisions that need to made on the way and how those decisions may need to adapt as things progress. The article will not address any specific graphic techniques (e.g. slicing and optimising) as this varies from paint package to package and is not the subject of the article. You will of course need to know how to do these things and I am assuming that you already have this basic knowledge.
