This website was built using xhtml 1.0 Transitional and CSS2, with PHP 'includes' and scripting for features such as our Contact form. Strictly speaking, our stylesheet doesn't fully validate, due to a hack we've included to make Safari behave itself, but in every other respect, this is a well-trained website, and we think it conforms in spirit.
The Chroma Design banner is in Gill Sans Book, as are the page and section headers. All body text is rendered via a descending list of typefaces, starting with Lucida Grande (if you are reading this on a Mac) and Lucida Sans Unicode (PC), degrading to a generic sans-serif font.
The auto-scrolling 'top of page' link in our Portfolio uses the Scriptaculous javascript library, and we have used a smattering of other javascripts here and there, for preloading images and controlling the page footers. We've had those in our goodies library for a long time, and we cannot remember who wrote them. We do know that a nice man in Ireland provided the statistics scripts.
We used Adobe Photoshop CS2, Illustrator CS2 and Dreamweavers 8.0 & 9.0 to build the graphics and write the markup. Files were written on an Intel Mac and an aged and rather stately Dell PC. They were uploaded via Mozilla Firefox FireFTP and/or FileZilla Client FTP, depending on our mood at the time. While they were uploading, we drank Taylor's Yorkshire Gold, from a variety of mugs, most of which still reside on the desk.
The quotation, "The details are not the details, they make the design" is from Charles Eames.
