Border Images: CSS3 has introduced a new feature that is border images. This feature allows you to exchange a border with an image. It helps you specify an image in place of a plain solid coloured border.
CSS3 selectors: CSS selectors are more updated and improved in CSS3 version. With these selectors, DOM elements can be chosen on the bases of their attributes easily. There is no need to specify classes and ID’s for each and every element. You can use the field elements to perform styling functions.
Font Additions: Adding fonts is easy in CSS3 and all you need to do is just upload the file to your server, link to the CSS file and add fonts as per your choice.
Opacity levels: In previous versions, designers had to create a new image or make use of CSS filters. But in CSS3, you simply have to provide an input that will get the desirable effects.
