Adobe Dreamweaver makes adjusting to cascading style sheets quite simple. Dreamweaver's user interface allows you to edit CSS styles easily. In fact, using and creating CSS styles is an inherent part of the development workflow. As a developer you must be familiar with Dreamweaver's Group Panel section. This is where you will be working primarily.
Cascading Style Sheets (or CSS) provide a method of controlling how HTML documents appear. Replacing a web site's style sheet can radically alter the way it appears. This can make it easier to rebrand a website or target different display types, such as: print, mobile phones and projectors. By separating visual design elements (fonts, colors, margins, and so on) from the structural logic of a Web page, CSS give Web designers the control they crave without sacrificing the integrity of the data-thus maintaining its usability in multiple environments. In addition, defining typographic design and page layout from within a single, distinct block of code - without having to resort to image maps, tags, tables, and spacer GIFs - allows for faster downloads, streamlined site maintenance, and instantaneous global control of design attributes across multiple pages.
You can use Cascading Style Sheets (CSS) in Dreamweaver to apply style elements consistently across multiple pages of a site. CSS styles offer great flexibility in that style is not confined to text objects. You can define positioning and formatting styles to text, images, tables, layers, and so on.
