// When the DOM is ready... $(function(){

If JS is disabled, the form will still be useable. // NOTE: // Sometimes using the .hide(); function isn't as ideal as it uses display: none; // which has problems with some screen readers. Applying a CSS class to kick it off the // screen is usually prefered, but since we will be UNhiding these as well, this works. $(".name_wrap").hide(); $("#company_name_wrap").hide(); $("#special_accommodations_wrap").hide();
