This is an experimental technology
Check the Browser compatibility table carefully before using this in production.
Note: The :blank
selector is considered at risk, as the CSSWG keeps changing it.
See CSSWG issue #1967.
The :blank
CSS pseudo-class selects empty user input elements (e.g. <input>
or <textarea>
).
:blank
In eventual supporting browsers, the :blank
pseudo-class will enable developers to highlight in some way input controls that are not required, but still have no content filled in, perhaps as a reminder to users.
<textarea></textarea>
textarea:blank { border: 3px solid red; }
