You can create page layouts by manually inserting div tags and applying CSS positioning styles to them. A div tag is a tag that defines logical divisions within the content of a web page. You can use div tags to center blocks of content, create column effects, create different areas of color, and much more.
If you’re unfamiliar using div tags and Cascading Style Sheets (CSS) to create web pages, you can create a CSS layout based on one of the pre-designed layouts that come with Dreamweaver. If you’re uncomfortable working with CSS, but are familiar with using tables, you can also try using tables.
