Reed Insurance was built in ModX, with a lot of custom built PHP.
I built the downloads page so that the client only has to pop in linked text to the PDF, then the PHP script separates the links into an unordered list with a new target on each link, and calculates the size of the PDF for the user's reference, without the client having to worry about it.
As the client wanted to use anchor links on this page, so visitors are taken to the right part of the page from different areas of the site, this page is actually composed of different client-controlled content areas which are all pulled into the same live page. I used this same technique on several areas of the site so there was no risk of important layout elements being overwritten when the client makes changes within the WYSIWYG.
The insurance enquiry forms are all custom built, and I'm (justifiably!) proud of the custom features I built into them, including:
I also built a lot of (if I do say so myself) clever CSS for Reed Insurance. I am particularly proud of the tabs at the top of the screen, which all use the same single image with background positioning to show different areas of the image. When you hover over a link, the image will actually move one pixel, without seeming to jump, to cover up the small dividing lines on both sides of the highlighted tab. I also made use of CSS image replacement on the site headings. As it is a fairly small web site, I didn't see the need to set up a technique like sIFR text to show the headings in a unique font. Instead, I use PHP to check which page the user is currently on, then set an ID on the H tag; spans inside the H tag contain the web text for search engines and users without CSS to see, while this will be hidden to users with CSS who instead see the unique font image. Using PHP allowed me to do this automatically, so the client wouldn't have to worry about it.
