Non-standard
This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

The :-moz-first-node CSS pseudo-class is a Mozilla extension that represents any element that is the first child node of some other element. It differs from :first-child because it does not match a first-child element with (non-whitespace) text before it.

Note: Any whitespace at the start of an element is ignored for the determination of :-moz-first-node.

Syntax

:-moz-first-node

Example

CSS

span:-moz-first-node {
  background-color: lime;
}

HTML

<div>
  <span>This matches!</span>
  <span>This doesn't match.</span>
</div>

<div>
  Blahblah.
  <span>This doesn't match because it's preceded by text.</span>
</div>
