Use! Important in CSS applied with Jquery

Question

I have a code in Jquery, and would like to apply the !important in the CSS, as below:

$('.prodMenor:eq(6)').css('margin-right','0!important');

But the way I did it’s not working, there’s another way?

I found an alternative solution:

CSS:

.imp{margin-right: 0!important}

Jquery:

    $('.prodMenor:eq(6)').addClass('imp');

Resolved! :)
