:nth-last-child()

The :nth-last-child() CSS pseudo-class matches elements based on their position among a group of siblings, counting from the end.

Try it

Syntax

The nth-last-child pseudo-class is specified with a single argument, which represents the pattern for matching elements, counting from the end.

:nth-last-child( <nth> [ of <complex-selector-list> ]? )

Keyword values

odd

Represents elements whose numeric position in a series of siblings is odd: 1, 3, 5, etc., counting from the end.

even

Represents elements whose numeric position in a series of siblings is even: 2, 4, 6, etc., counting from the end.

Functional notation

<An+B>

Represents elements whose numeric position in a series of siblings matches the pattern An+B, for every positive integer or zero value of n. The index of the first element, counting from the end, is 1. The values A and B must both be <integer>s.

Examples

Example selectors

tr:nth-last-child(odd) or tr:nth-last-child(2n+1)

Represents the odd rows of an HTML table: 1, 3, 5, etc., counting from the end.

tr:nth-last-child(even) or tr:nth-last-child(2n)

Represents the even rows of an HTML table: 2, 4, 6, etc., counting from the end.

:nth-last-child(7)

Represents the seventh element, counting from the end.

:nth-last-child(5n)

Represents elements 5, 10, 15, etc., counting from the end.

:nth-last-child(3n+4)

Represents elements 4, 7, 10, 13, etc., counting from the end.

:nth-last-child(-n+3)

Represents the last three elements among a group of siblings.

p:nth-last-child(n) or p:nth-last-child(n+1)

Represents every <p> element among a group of siblings. This is the same as a simple p selector. (Since n starts at zero, while the last element begins at one, n and n+1 will both select the same elements.)

p:nth-last-child(1) or p:nth-last-child(0n+1)

Represents every <p> that is the first element among a group of siblings, counting from the end. This is the same as the :last-child selector.

Table example

HTML

<table>
  <tbody>
    <tr>
      <td>First line</td>
    </tr>
    <tr>
      <td>Second line</td>
    </tr>
    <tr>
      <td>Third line</td>
    </tr>
    <tr>
      <td>Fourth line</td>
    </tr>
    <tr>
      <td>Fifth line</td>
    </tr>
  </tbody>
</table>

CSS

table {
  border: 1px solid blue;
}

/* Selects the last three elements */
tr:nth-last-child(-n + 3) {
  background-color: pink;
}

/* Selects every element starting from the second to last item */
tr:nth-last-child(n + 2) {
  color: blue;
}

/* Select only the last second element */
tr:nth-last-child(2) {
  font-weight: 600;
}

Result

Quantity query

A quantity query styles elements depending on how many of them there are. In this example, list items turn red when there are at least three of them in a given list. This is accomplished by combining the capabilities of the nth-last-child pseudo-class and the general sibling combinator.

HTML

<h4>A list of four items (styled):</h4>
<ol>
  <li>One</li>
  <li>Two</li>
  <li>Three</li>
  <li>Four</li>
</ol>

<h4>A list of two items (unstyled):</h4>
<ol>
  <li>One</li>
  <li>Two</li>
</ol>

CSS

/* If there are at least three list items,
   style them all */
li:nth-last-child(n + 3),
li:nth-last-child(3) ~ li {
  color: red;
}
