Question

I’ve looked: How to set margin with jquery?

This is what I am trying:

$(document).ready(function () {
    $(".content").each(function (el) {
        el.css('margin', '0px');
    })
});

This isn’t working though; right now I have to set the margin to zero in the style sheet.

This ought to do the trick.

$(document).ready(function () {
    $(".content *").css('margin', '0px');
});

The problem is you are setting the margin on the element itself, and not on its children.
The selector .content * means “anything inside an element with class content”. (Anything, and not just direct children.)
