If statement #4 above is passed, this paragraph should have a font size of 20px and a line height of 30px; the rule applied is "p {font-size: 20px; line-height: 150%;}".. This emphasized text should also have a line height of 30px, because em is a child of p, and inherits the line height value of p; this is even though the rule "em {font-size: 12px}" is applied, so em should have a font size of 12px.
All other properties of this page should be UA-default.
