I was just wondering if I should use ":" or "::" when using :(:)before and :(:)after. I am wondering if there is a difference.

Did you see any difference when you changed from 1 to the other? – takendarkk Dec 01 '16 at 20:04

Did you search for this? I imagine this would be extremely easy to find information on. – Carcigenicate Dec 01 '16 at 20:04

1`::before` is correct, `:before` exists for backwards-compatibility. – Niet the Dark Absol Dec 01 '16 at 20:05

The ::before notation (with two colons) was introduced in CSS3 in order to establish a discrimination between pseudo-classes and pseudo-elements. Browsers also accept the notation :before introduced in CSS 2.
Source: https://developer.mozilla.org/en-US/docs/Web/CSS/::before
As before is a pseudo ELEMENT and not a pseudo CLASS (like :hover) two colons is better (thus following the CSS3 standard).
