I have seen it on some sites where the textarea input can by drawn only downward but not to sideways.
<textarea cols="10" rows="5" charswidth="23" name="text_body"></textarea>I have seen it on some sites where the textarea input can by drawn only downward but not to sideways.

    textarea {
  resize: vertical;
}<textarea cols="10" rows="5" charswidth="23" name="text_body"></textarea>This can be achieved via CSS.
