title: jQuery animate and slideDown simultaneously
body: <p>How can I make animate and slide down functions below to happen at exactly same time and duration:</p>
  
  <pre><code>current_item.css('margin-left', 0);
  current_item.animate({ 'marginLeft': '20px'});
  current_item.slideDown(300, 'swing');
  </code></pre>
  
  <p>My code above is animating it before sliding down. If I move animate function below, it is sliding down and then animating</p>
