What is CSS3?
CSS stands for Cascading Style Sheets and is a part of HTML. CSS is all about the presentation of a website or mobile application. CSS3 is the latest version of CSS, following on from CSS2.
CSS3 contains much of what was included in CSS2, but contains updates such as rounded corners, gradients, shadows, grid layouts and multi-columns. This means that there are now even more opportunities to make your website development project or mobile application unique.
