You can centrally manage all the styles for your web site from one global menu with Cascading Style Sheets (CSS) in Dreamweaver. A single CSS file can supply formatting specifications for fonts, colors, borders, background colors, and many other elements for your entire site. This also gives you the convenience of single-source editing to change any of your formatting options.

Behaviors in Dreamweaver enhance your web pages (such as the popular mouse rollover effect) and provide added functionality to the program. Use any of dozens of behaviors included with Dreamweaver or extend Dreamweaver by installing freely downloadable extensions to the program.
