Re-explain

Vendor prefixes indicate experimental CSS features:

  • -webkit-: Chrome, Safari, newer Edge
  • -moz-: Firefox
  • -ms-: Internet Explorer, old Edge
  • -o-: Opera (old)
.element {
  -webkit-transform: rotate(45deg); /* Safari/Chrome */
  -moz-transform: rotate(45deg);    /* Firefox */
  -ms-transform: rotate(45deg);     /* IE */
  transform: rotate(45deg);         /* Standard */
}

Modern CSS features need fewer prefixes. Use tools like Autoprefixer to add prefixes automatically.
