CSS3 Basics
If you have ever been in the world of web development, chances are that you have heard of CSS, or more formally, cascading style sheets. If you aren't familiar with CSS, it is a language that is used to define how HTML-based content is displayed on the web. CSS can be used to control layout, spacing, colors, fonts, and much more, and has been an integral component of "the Web" since it began gaining popularity in the mid-1990s.
If you are actively engaged in designing or developing web content, then chances are that you have also heard of CSS3. Though you may have heard of it, you might be wondering what it is, and how it differs from existing implementations of CSS.
All technologies mature over time, hence the common adoption of version numbers and terms such as "beta." These labels allow you to identify which version of a particular technology you are using, and thus you can reliably expect what kind of features that piece of software will support. CSS3 is the third iteration of the CSS standard; it is a maturation of the cascading style sheets language that defines new features that allow for richer presentation of content within HTML.
