jQuery changing css class to div

Question

If I have one div element for example and class \'first\' is defined with many css properties. Can I assign css class \'second\' which also has many properties differently

Answer 1

You can add and remove classes with jQuery like so:

$(".first").addClass("second")
// remove a class
$(".first").removeClass("second")

By the way you can set multiple classes in your markup right away separated with a whitespace
