They are most often used to select - # elements in a given position: - # * <tt>:root</tt> -- Match the element only if it is the root element - # (no parent element). - # * <tt>:empty</tt> -- Match the element only if it has no child elements, - # and no text content. - # * <tt>:content(string)</tt> -- Match the element only if it has <tt>string</tt> - # as its text content (ignoring leading and trailing whitespace). - # * <tt>:only-child</tt> -- Match the element if it is the only child (element) - # of its parent element. - # * <tt>:only-of-type</tt> -- Match the element if it is the only child (element) - # of its parent element and its type. - # * <tt>:first-child</tt> -- Match the element if it is the first child (element) - # of its parent element. - # * <tt>:first-of-type</tt> -- Match the element if it is the first child (element) - # of its parent element of its type. - # * <tt>:last-child</tt> -- Match the element if it is the last child (element) - # of its parent element. - # * <tt>:last-of-type</tt> -- Match the element if it is the last child (element) - # of its parent element of its type. - # * <tt>:nth-child(b)</tt> -- Match the element if it is the b-th child (element) - # of its parent element. The value <tt>b</tt> specifies its index, starting with 1. - # * <tt>:nth-child(an+b)</tt> -- Match the element if it is the b-th child (element) - # in each group of <tt>a</tt> child elements of its parent element. - # * <tt>:nth-child(-an+b)</tt> -- Match the element if it is the first child (element) - # in each group of <tt>a</tt> child elements, up to the first <tt>b</tt> child - # elements of its parent element. - # * <tt>:nth-child(odd)</tt> -- Match element in the odd position (i.e. first, third). - # Same as <tt>:nth-child(2n+1)</tt>. - # * <tt>:nth-child(even)</tt> -- Match element in the even position (i.e. second, - # fourth). Same as <tt>:nth-child(2n+2)</tt>. - # * <tt>:nth-of-type(..)</tt> -- As above, but only counts elements of its type. - # * <tt>:nth-last-child(..)</tt> -- As above, but counts from the last child. - # * <tt>:nth-last-of-type(..)</tt> -- As above, but counts from the last child and - # only elements of its type. - # * <tt>:not(selector)</tt> -- Match the element only if the element does not - # match the simple selector. - # - # As you can see, <tt>:nth-child</tt> pseudo class and its variant can get quite - # tricky and the CSS specification doesn't do a much better job explaining it. - # But after reading the examples and trying a few combinations, it's easy to - # figure out. - # - # For example: - # table tr:nth-child(odd) - # Selects every second row in the table starting with the first one. - # - # div p:nth-child(4) - # Selects the fourth paragraph in the +div+, but not if the +div+ contains - # other elements, since those are also counted. - # - # div p:nth-of-type(4) - # Selects the fourth paragraph in the +div+, counting only paragraphs, and - # ignoring all other elements. - # - # div p:nth-of-type(-n+4) - # Selects the first four paragraphs, ignoring all others. - # - # And you can always select an element that matches one set of rules but - # not another using <tt>:not</tt>. For example: - # p:not(.post) - # Matches all paragraphs that do not have the class <tt>.post</tt>. - # - # === Substitution Values - # - # You can use substitution with identifiers, class names and element values. - # A substitution takes the form of a question mark (<tt>?</tt>) and uses the - # next value in the argument list following the CSS expression. - # - # The substitution value may be a string or a regular expression.
