When a user successfully logins on the front-end is there a way to (using the Login Extra or some other method) append a class to say, the body tag? And when the user signs-out to remove that same class?

I know how to add/remove classes using js but I don't know how to do it based soley on whether someone is signed-in or not.

The only thing I can think of is a little funky. You could put a snippet tag inside the body tag:

<body class="whatever [[!addClass]]">

/* addClass snippet */
return $modx->user->hasSessionContext('web') ? 'YourAddedClass' : '';

I should mention another way to go. It's a little slower, but arguably more "correct" from a design standpoint.

You could add a class to the body tag in the template, and alter the CSS on the fly to define what the class does. The snippet tag could go anywhere on the page.

$visibility = $modx->user->hasSessionContext('web') ? 'block' : 'hidden';

$css = '
   .my_class {
    display:
    ' . $visibility . ';
}';

$modx->regClientCSS($css);

That will inject the CSS code at the end of the head section, where it will override any existing CSS loaded earlier.
