I am reviewing many of these topics now, coming back to it at the end of the course and I realise how vitally important it is to create the global structure before putting in the details. I have found this not only for the overall structure but also for paragraphs, lists, headings and many of the other tags that get used within the body. The reason for this is that it is so easy to get caught up in the work that the final tags get forgotten. It also becomes essential when nesting e.g. div within div or tables within tables and so on. When I first looked at this I tended to be a bit disregardful of this - to my cost. I've realised now that nothing that is taught on this course can be disregarded. It builds up the whole in steps in a way that makes it possible to understand the whole. Before starting this course I was trying to do this from a book and from a Do it yourself CD. I couldn't make head or tail of it. Now I understand it.
