PHP changing class while running

Question

I've a problem with loading new class from my CSS file. Actually, I think it is some thing else because if I try to change the background to red just to check if it is working, nothing happens

function logging_error()
{
    $html = new DOMDocument();
    @$html->loadHTML("login.php");
    $divToShake = $html->getElementsById('login_form');
    $divToShake->setAttribute("background-color", "red");
    $divToShake->item(0)->class = 'shake';
    //echo $divToShake->getAttribute('class') ;
}

The problem is that you have an extra s in getElementsById(). It should be:

$divToShake = $html->getElementById('login_form');

What about this ?

$divToShake->setAttribute("style", "background-color: red;");

or maybe this

$divToShake->setAttribute("background", "red");
