CSS3 is the modularization of Cascading Style Sheets which allows additions to the specification and also limits the properties used in a given situation. It offers great flexibility and makes it much easier to recreate previously complex effects. It incorporates many time-saving rules like text-shadow, box-sizing, opacity, multiple backgrounds, border-radius, border-image, multi-column layout, etc. CSS3 is empowered by various modules which make it a novel web design trend of 2011.
One of the biggest advantages of modules in CSS3 is that they allow the specification to be completed and approved more quickly, because segments are completed and approved in chunks. This also allows browser and user-agent manufacturers to support sections of the specification and also to keep their code bloat to a minimum by only supporting those modules that make sense. For example, a text reader would not need to include modules that only define how an element is going to display visually. But even if it only included the aural modules, it would still be a standards-compliant CSS3 tool.
Some of the new features of CSS3 are
