Why there is -moz-XXX and -webkit-XXX in the CSS3?

It's because they're vendor-specific webkit and moz prefixed properties are not standard properties. That "namespacing" allows vendors to test new cool features, and if they're great, they can be incorporated into the standards. This is what is happening with CSS3: Mozilla and the Webkit team tried cool things, and now they're going to become standard.It's just not done yet.

Eventually it'll become a consistent border-radius property.

For instance, -webkit-transition-property only works on Webkit-based browsers. Anyways, -webkit-border-radius and -moz-border-radius don't exactly work the same.It's because each vendor, even though they're doing similar things, are allowed to implement features the way they want. The standard will establish a standard way, but everyone is free to do whatever they want within their own namespace.

Webkit-border-radius and -moz-border-radius were created before the CSS3 borders standard was a complete (it is still not an approved standard - it is currently a Candidate Recommendation). The standard calls for a border-radius only, as you can see from the specification. They are specific to mozilla and webkit - once the standard is approved this should change to be border-radius on all supporting browsers.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
