:nth-of-type() - CSS: Cascading Style Sheets 编辑

The :nth-of-type() CSS pseudo-class matches elements of a given type (tag name), based on their position among a group of siblings.

/* Selects every fourth <p> element
   among any group of siblings */
p:nth-of-type(4n) {
  color: lime;
}

Syntax

The nth-of-type pseudo-class is specified with a single argument, which represents the pattern for matching elements.

See :nth-child for a more detailed explanation of its syntax.

Formal syntax

:nth-of-type( <nth> )
where 
<nth> = <an-plus-b> | even | odd

Examples

Basic example

HTML

<div>
  <div>This element isn't counted.</div>
  <p>1st paragraph.</p>
  <p>2nd paragraph.</p>
  <div>This element isn't counted.</div>
  <p>3rd paragraph.</p>
  <p class="fancy">4th paragraph.</p>
</div>

CSS

/* Odd paragraphs */
p:nth-of-type(2n+1) {
  color: red;
}

/* Even paragraphs */
p:nth-of-type(2n) {
  color: blue;
}

/* First paragraph */
p:nth-of-type(1) {
  font-weight: bold;
}

/* This has no effect, as the .fancy class is only on the 4th p element, not the 1st */
p.fancy:nth-of-type(1) {
  text-decoration: underline;
}
