Modify the appearance of the elements dynamically by applying styles from the CSS file without relying on the

In my CSS file, I have the following styles:

.myClass {
...
}

.myClass:focus {
...
}

Am I able to modify these styles from my code? For instance, can I change the focused style of an input element when a button is pressed?

To update a class in a .css file, you can create a new class and then switch the old class to the new one using jQuery.

You can change the class to a new one by simply using .attr(), like so:

 $("#td_id").attr('class', 'newClass');

If you want to add a class instead of replacing it, you can use .addClass() like this:

 $("#td_id").addClass('newClass');

Alternatively, you can swap classes quickly with .toggleClass():

 $("#td_id").toggleClass('change_me newClass');
