I am wondering if it is better to put your html in javascript or in your html files. For example having my js file have this $('<div>').addClass('test').append( $('<p>').text('test1'), $('<span>').text('test2'), $('<span>').text('test3') ).insertAfter( $('#test1') ); VS My html file looking like this <div id="#test1"></div> <div class="test"> <p>test1</p> <span>test2</span> <span>test3</span> </div> and the js file have: $('.test').show();
