Jewel - defaults.css error

[Maria Jose Esteve]

Hi, I wanted to check with you...
in the defaults.css of the Jewel project you have these lines:

*, :after, :before {
  box-sizing: border-box; }


For me ":after" and ":before" are not correct and should be changed to:

*, ::after, ::before {
  box-sizing: border-box; }


Am I right, can I correct it?
