css - :nth-child related only to specific class or element -

it's possible assign :nth-child specific element, without count other element in middle (ex http://jsfiddle.net/mgc4v/ <*br>).

<p>1</p> <br> <p>2</p> <p>3</p>  p:nth-child(3) {     background-color:red; }

the red line second one, not third..thanks

p:nth-of-type(3) {     background-color:red; }

will select third <p> element :) , question ?
