Introduction

CSS3 (Cascading Style Sheets, Level 3) is a style sheet language that specifies style formatting for websites, such as color, font size, and layout. It is most commonly used on HTML pages. Unlike HTML, CSS focuses on the style and design of the website rather than the content. The main utility of CSS is making aesthetic changes to a website without rewriting the code on every single page. Clarity has implemented CSS3 successfully on a variety of web design projects.

Simplified Design Elements

One of the benefits of CSS3 web design is that, though it’s powerful, it’s also a relatively simple web language. What makes it so simple is that it is split into logical and user-friendly modules. The most common (and important) CSS3 modules are: backgrounds and borders, text effects, animations, layouts, and user interface. Within each of these modules is a set of customizable functions, which allows for greater flexibility in custom development, providing for the optimum user experience and a number of immersive elements.

CSS3 Web Design Versus Other Versions of CSS

CSS is designed to be “backwards compatible,” which means CSS3 is fully compatible with other versions of CSS. The main difference between CSS3 and prior versions is that the other versions did not contain CSS3’s modules. Each module contains new features and capabilities, and a more user-friendly, organized experience.

CSS3 Web Design and Your Web Site

On top of great content, it is of the utmost importance that your website be attractive, well laid-out, and easy to navigate. CSS3 is a great resource for accomplishing this critical goal. Another benefit of CSS3 is that, while it is important for a developer to design your site and provide ongoing support, certain elements can be tweaked or updated without needing to have a significant background in web design. For example, there are a variety of CSS3-generating tools that will help you accomplish small web tasks without writing a single word of code. This fits in perfectly with an on-the-go or do-it-yourself business owner who needs quick fixes to simple problems.
