CSS3 makes it possible to programme effects that until now were only possible with Flash
Some new features it offers include:
Border radius: this feature allow you to give a round edge to borders of elements, without the need to use strategically positioned images, reducing the web’s load and making it more adaptable to future changes to the design
Box shadow: for creating any kind of shadows on any element within the web.
Gradient: makes it possible to use a colour gradient as a background colour.
Transitions: for generating animations, such as zoom, rotation…
Transform: this applies transformations such as perspective, rotation, changes of scale…
All these features make it possible to avoid using scripts or tools such as Flash, making the website much lighter, and above all more spectacular.
