Using basic jQuery filters

JQuery filters are used to refine results returned from selectors.

Examples:

$("p:first"): of the retirned <p> tags, select the first one
$("p:even"): select the even number <p> tags
$("a:gt(1)"): of the <a> tags, select those after the 0th and 1st
$("p:not(p:eq(2))"): select all the <p> tags except the one at index 2
