CSS is the specification of a series of modules. CSS generally exists on a stylesheet, which is attached to a document of HTML code. The two elements are used to create what we know as a website. CSS allows web designers to customize websites using the attached stylesheet. The use of CSS and a stylesheet allows web designers to avoid having to create more complex code within an HTML document. Overall, the use of CSS makes it quicker and easier to design the overall look of a website, and generally also allows the website to have a quicker load time. CSS3 is the newest version of CSS. Even though CSS3 is a new form of coding, many of its properties are compatible with current browsers. One of the current uses of CSS3 is to complement plug-ins like Javascript, and make more beautiful website animations without increasing load time. These animations and transitions can be implemented to enhance the overall user experience of a website.
