Append one class to another

[Sleidia]

Hi guys,

Is it possible to append the content of one CSS class to an element that already uses a different class?

#class1 {
font-weight: normal;
}

#class2 {
font-weight: bold;
}

<--! my_element uses #class1 -->
document.my_form.my_element.style += (content of #class2 ) ???

Thanks for the help !

Wow ... sorry .... I've found it already

document.my_form.my_element.className+= ' class2';
