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.
Note: In Selectors Level 4 the :empty
selector was changed to act like :-moz-only-whitespace
, but no browsers currently support this yet.
The :-moz-only-whitespace
CSS pseudo-class matches elements that have no child nodes at all, or only have empty text nodes or text nodes that have only whitespace in them.
Syntax not found in DB!
<div> </div>
div { border: 4px solid red; } :-moz-only-whitespace { border-color: lime; }
Briefly defined as :blank
in Selectors Level 4, but then the functionality was merged into :empty
and :blank
redefined to mean empty <input>
.
