My most recent freelance work was as lead developer for PlainsCapital’s relaunch of its site and subsidiary sites (PlainsCapital Bank, PlainsCapital Insurance, and others). Formerly PNBFinancial, the company decided to redesign its sites as part of its company-wide rebranding.
The sites launched last week and its standards-compliant layout includes valid XHTML 1.1 and CSS (just CSS for layout). I’ve also added a section to my portfolio which explains several of the CSS techniques used throughout the site.
That discussion of the techniques you used is a good idea. I just might do that with some of my own work. One thing that would help make it clearer would be to have some screenshots of the area in question for the code spotlight. Just to show the reader the cause and effect.
