:-moz-first-node
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
.
