I'm trying to convert a PSD I designed into HTML/CSS. I'm familiary with HTML/CSS but relatively new to photoshop. I'm working on putting a slice of the header into html, so that the background of the header expands when you change the window size. No matter how I slice my background, it won't tile seamlessly. I'm doing something wrong, and I wanted to know if anyone knows of any GOOD DESCRIPTIVE tutorials on how to properly slice and code a PSD to HTML/CSS. Any ideas?
