I have designed a wireframe of the agreed layout with XHTML 1.0 (transitional) and CSS. This was one of the biggest challenges to date on the project as it involved a very steep learning curve in these web standard techniques.
Read these FAQ by the Web Standards Project and one of the most cited articles on web standards to see why this was important for the context of my final project.
Although some basics were covered during the PG Certificate module it required much more learning and numerous trial & error sessions to make it suit the layout and also validate. See this article on validation by the W3C to understand the significance.
I created 2 versions of the wireframe to accommodate different header image sizes.
See the first wireframe version here and also the validation result and the second version with its proof of validation for the markup. The CSS used is in both versions also validates.
Probably only somebody who is not a natural born web developer/programmer (I personally have a background in Graphic Design and DTP) and has worked many hours to get the validation screen from red to green can understand my outburst of joy when reading the magical words:
