browser - Prefix for CSS3 isn't required? -

-

i busy website using latest chrome.

for no reason, started searching through code using inspect element.

i scrolled down, after saw rare happening. -moz- -o- -ms- -webkit- crossed, except box-shadow itself. same happening every single css3 element, such gradient, text-shadow, transition, box-shadow.

i wondering if it's chrome. put parts of code there prefix, between /* , */. started named below browsers, using 127.0.0.1, , gives me result wanted, without prefixes.

google chrome 28.0.1500.95 -webkit-

internet explorer 10.0.9200 -ms-

mozilla firefox 23.0 -moz-

opera 15.0.1147.153 -o-

why kept telling me, need it? when browsers support it? (i mean that, these 4 prefixes catch browsers).

according caniuse.com (first google result) vendor prefix support few outdated versions of mozilla , webkit-based browsers.
