Check the Browser compatibility table carefully before using this in production.
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 {
/* ... */
}
Examples
CSS
span:-moz-first-node {
background-color: lime;
}
HTML
<p>
<span>This matches!</span>
<span>This doesn't match.</span>
</p>
<p>
Blahblah.
<span>This doesn't match because it's preceded by text.</span>
</p>
