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
This matches!
This doesn't match.
Blahblah.
This doesn't match because it's preceded by text.
