Many times, when creating a site, I need hidden elements on a page that I must later make visible. Of course it would be great if one could simply hide them via CSS, and later [easily] show them via javascript. However this is not the case, javascript has some difficulties overriding styles set in a stylesheet. So, I've found the best way to accomplish this is to use a combo of CSS and javascript in a two-step process:

1. Hide the elements via CSS class – so they are hidden when the user first sees the page
2. Hide the elements via javascript and remove the corresponding CSS class, after the DOM has loaded.

The second step has the potential to be quite expensive on the DOM, but feel that it's an acceptable trade-off because they elements in question are already hidden. This way they are ready to be manipulated, one doesn't need to worry about fiddling with CSS classes or styles.

## Stylesheet
.hidden {
  display: none;

        if(e.isActive()){
          e.indicate();
          document.ajaxRequest(e, e.readAttribute('src'), 'get', event, e.serialize());
        }
      });
