Title: Add pseudo-elements to universal selector in print media query

The pseudo-elements `:before` and `:after` are not targeted by the universal `*` selector. When the page is printed the CSS properties of any pseudo-elements will only be overridden if they are being inherited from their selector. Any styles that have been defined directly on a pseudo-element are unaffected.
