This tests some cases of the statement in CSS2 section 5.3 that
If the universal selector is not the only component of a simple selector, the "*" may be omitted.
and the statement in section 5.10 that
Pseudo-classes are allowed anywhere in selectors while pseudo-elements may only appear after the subject of the selector.
Nothing in this paragraph should be red, whether it is on the first line or not. This is because pseudo-elements are only valid when attached to the subject of the selector.
The first line of this paragraph should be purple.
The first line of this paragraph should be purple. There
should be nothing at all unusual about these words.
Specifically, they should not be red, and their first letter
should not be larger. This is because
:first-line only apply to block-level elements.
Any emphasized text in a link within this blockquote should be red on a green background. This is a link to the web standards project with emphasized text within it.
div, such as the word div earlier in this sentence (but NOT this paragraph) should begin with the words "Beginning of an Element" in navy on a yellow background.
This paragraph should begin with those words.
