Dreamweaver Cs3 And Css

Because of its ability to separate design from content, Cascading Style Sheets (CSS) has become an extremely important technology in web development. A single CSS document can contain information regarding the position of elements on all the pages in a web site as well as style information such as font, sizes and colours. In terms of building websites, CSS definitely represents the future.

Adobe Dreamweaver has long had support for the use of CSS and has responded to the growing importance of this pivotal technology. Dreamweaver's implementation of CSS is all the more important since many of the people using the program are not specialist web developers and rely on Dreamweaver to guide them through the maze of technologies which drive web pages.

One of the most noticeable changes in this the latest version of Dreamweaver is that users are now positively encouraged to create web pages using CSS for page layout rather than tables. Each time a new web page or template is created, Dreamweaver offers you a choice of basing the page on one of about thirty preset CSS layouts with names like "3 Column Elastic" and "3 Column Fixed".

Pages created using CSS rely heavily on the use of the HTML DIV element, a multipurpose container of web content. Choosing one of the Dreamweaver CSS presets creates a page containing a series of DIV elements complete with placeholder text and the CSS code necessary to control the position and dimension of the DIVs. The placeholder text and HTML code both contain brief explanations of the techniques used and advice on how to customise these basic pages for your own purposes.

CSS works most efficiently when you can place all of your CSS code in one external file and link that file to each of your HTML pages. Dreamweaver CS3 still does not make it easy for inexperienced users to create CSS-based pages in this way. If the user creates ten web pages based on Dreamweaver's preset CSS designs, each will have its own code embedded within the page itself. There is, however, a great feature for moving embedded code across to an external CSS file. You just select a series of CSS definitions, right-click and choose "Move CSS Rules" which is available in the "CSS Styles" section of the context menu.

Although this ability to move CSS around is really great, it's not something that beginners will necessarily think of doing. It points to the fact that Dreamweaver could still do with a few enhancements to its implementation of CSS.

Another area where Dreamweaver still handles CSS inefficiently is the way in which it generates CSS class styles with names like "style1", "style2", etc. whenever the user applies attributes like font, size or colour to highlighted text. This must be really confusing for beginners and can easily be solved by simply removing these "raw" attributes and replacing them with CSS-friendly options.
