textarea’s rows, and cols attribute in CSS
<textarea rows=”4″ cols=”50″></textarea> It is equivalent to: textarea { height: 4em; width: 50em; } where 1em is equivalent to the current font size, thus make the text area 50 chars wide. see here.

Use jQuery to hide a DIV when the user clicks outside of it
Had the same problem, came up with this easy solution. It’s even working recursive: $(document).mouseup(function(e) { var container = $(“YOUR CONTAINER SELECTOR”); // if the target of the click isn’t the container nor a descendant of the container if (!container.is(e.target) && container.has(e.target).length === 0) { container.hide(); } });
