Web 2.0 Website Design – Importance of CSS (Cascading Style Sheets)

Cascading Style Sheets, or CSS, gained web development popularity in the year 2000. It was originally created in 1997 for programmers to separate content from design and utilize HTML coding to properly markup content.

Web browsers now recognize all Level 1 CSS and many support Levels 2 and 3. Understanding CSS is as important as understanding HTML. CSS refers to style sheets, the technical specifications of a webpage that communicate with the Web browser to display the data on the web the way it is intended by the designer.


Cascading refers to the flow of the style sheets and defines the look of the webpage.

CSS is used anywhere there is XML or XHTML markup on a website and can be used to define the look of a Web page in other media such as projection and printing.

CSS is powerful because well written style sheets can be quickly updated, changing the look and feel of a website whenever desired without affecting the underlying XHTML. HTML tags and attributes are many and, in comparison, the 60 properties of CSS are easier to learn.

CSS is complex but provides many options. Plain HTML coding is an easier programming language but inhibits the web developer’s creativity. CSS allows the programmer to accomplish more in the the design and sophistication of a website.

CSS does not work in all browsers. When you write the style sheets for your website, you’ll want to include coding that includes variations for specific browsers so your website will be seen in the way it was envisaged.

* Experiment with the power of CSS. Style sheets are flexible and the only limit is the developer’s imagination.

* CSS complements HTML, ensuring that your website is viewed properly.

* CSS is an excellent tool for changing the fonts on your page. Color, size, style and typeface can all be written with CSS.

* HTML has become more of a content description within the coding of a website. CSS is the tool that describes the look and feel of your website.

* CSS is fun!

When you begin to design your website, it’s a good idea to work with a developer that is well-versed in CSS as well as HTML.
