Ok.... As promised I have placed links below to screenshots of the diary application I have been working on with Lito Lontoc. They are only shots of the login screen but they will give you an idea of the CSS styles that I have implemented for the users. At the top right hand corner you will see the style buttons users can choose which will allow them to pick their favourite colour. Once chosen, every page (form) they then go to will default to that chosen colour. Sorry about the OS and browser that is shown, but heck, thats what I have to use whilst at work ;-)
I will eventually post more screenshots of the diary itself which will include a calendar, scheduling, court lists etc etc.... which will give you more of an idea of the work that has gone into converting the mainframe app to a web interface.
