Syntax

:empty {
declaration block

Description

This pseudo-class matches elements that have no children. Element nodes and non-empty text nodes are considered to be children; empty text nodes, comments, and processing instructions don’t count as children. A text node is considered empty if it has a data length of zero; so, for example, a text node with a single space isn’t empty.

Example

The selector p:empty will match the first paragraph, but not the second or third, in this example:

<p></p>
<p> </p>
<p>Hello, World!</p>

In Firefox versions up to and including 2:

  • The selector body:empty always matches the body element.
  • The selector continues to match an element even after content has been added dynamically.

In Safari versions up to and including 2, when it appears in an internal style sheet (using <style> tags), this selector will always match. If this selector is used within an external style sheet, it works as designed.
