CSS to disable resizing
The CSS to disable resizing for all textareas looks like this:
textarea { resize: none; }
You could instead just assign it to a single textarea by name (where the textarea HTML is <textarea name=”foo”>):
textarea[name=foo] { resize: none; }
Or by id (where the textarea HTML is <textarea id=”foo”>):
#foo { resize: none; }
Validation errors
The above is only supported by the webkit browsers. If you run it through a CSS validator (such as the W3C CSS validator) you’ll get a warning like this:
Property resize doesn't exist in CSS level 2.1 but exists in [css3] : none
