These “min-height
/min-width
” rely on cols
and rows
attributes.
Eg. if cols
is missing or less than 1, its default value is 20, so the minimum width will be 20 characters width.
(cf. http://www.w3.org/TR/html5/forms.html#the-textarea-element)
The fact you cannot resize a textarea
under its initial dimensions is reported as a bug (https://code.google.com/p/chromium/issues/detail?id=94583) although
The user agent may restrict the resizing range to something suitable, such as between the original formatted size of the element, and large enough to encompass all the element’s contents.

Unfortunately it seems there’s no way for now to change this behaviour.
