AboutAndrew Hoffman Expertise I can field just about any question within this topic ranging from JavaScript to CSS, the two ingredients of DHTML. I`m very interested in the W3C and its validation rules for HTML, XHTML, and CSS, and enjoy answering questions of this type as well. I detest sleep and respond at all hours of the day or night.
Experience Experience in the area I've been working with DHTML and CSS for 7 years now and build/maintain websites of my own that implement DHTML navigation.
What I'm doing now My contract with Microsoft has ended and I am working for myself once again. Please contact me for any front-end work at antibland@gmail.com
