<textarea rows="2" cols="4" name="comments">
The above html tag will display users a textarea with 4 columns and 2 rows, but I found that I can enter as many words as I want into the textarea.
There is a restriction tag for input textbox, like maxlength="12".
But I don't know why I can't apply maxlength to restrict the number of words that are allowed to be entered in the textarea!
