Testing Ninth Testable Statement of Sec 5.7 of CSS2 Specification
9. This selector matches if E1 and E2 share the same parent in the document
tree and E1 immediately precedes E2.
PASS CRITERIA:
If statement #9 above is passed, then
this h3 heading should have a small vertical space between it and the h4
heading below; this is because of rule
"h3 + h4 {margin-top: -5mm}"
This is h4 heading
This paragraph should not be indented, because p follows div, and
rule is "div + p {text-indent: 0}".
This is h3 heading with class "new".
This is h4 heading that follows it. Margin top should be 10mm, because
of rule "h3.new + h4 {margin-top: 10mm}".
