-webkit-

Question

I hav seen this -webkit- many times in many codes
One time I see this with the css' border-radius property, but I know that border-radius property didn't require that, I mean without "-webkit-" the border-radius property will work. Then what is the use of "-webkit-"?

Answer 1

-webkit- is a vendor prefix for Chrome, Safari and other webkit-based browsers.
There are other prefixes for Mozilla Firefox, opera, IE, etc.
The prefixes are used for experimental features and for features that are under development, meaning that the syntax may not even be final.

Answer 2

It tells only webkit based browser will have border radius applied if i am not wrong!
