I know what is box-sizing but I have found in a lot of places that these 2 lines always come whit it like this: -webkit-box-sizing: border-box; -moz-box-sizing: border-box;
What are they?

16,936 PointsKevin's answer is correct but to add to his answer you can stay informed as to what is supported and by which browsers by using the caniuse website.
CanIUse shows which browsers support your searched elements and it lets developers know which browsers support those elements, which require vendor-prefixes and which have no support at all. As of right now, box-sizing is widely supported and do not require vendor-prefixes.
I hope this helps.
