Learning Web Design Third Edition- P13:Everything you need to know to create professional web sites is right here. Learning Web Design starts from the beginning defining how the Web and web pages work and builds from there. By the end of the book, you'll have the skills to create multi-column CSS layouts with optimized graphic files, and you'll know how to get your pages up on the Web. | Linking Within Your Own Site NOTE Linking to another spot on the same page works well for long scrolling pages but the effect may be lost on a short web page.
