Auto-expanding textarea

Question

For those interested in a jQuery version of Rob W's solution:

var textarea = jQuery('.textarea');
textarea.on("input", function () {
    jQuery(this).css("height", ""); //reset the height
    jQuery(this).css("height", Math.min(jQuery(this).prop('scrollHeight'), 200) + "px");
});
