Question

With jQuery, how can I find all locations where a specific padding-top value is applied and then increase it from its existing value?

I looked at selectors and I could not find such a thing.

Do you really mean to search the whole DOM? It’s quite inefficient:

$('*').each(function() {

    var padTop = $(this).css('padding-top'); // get the padding
    if (padTop > 0)
        $(this).css('padding-top', padTop + x); // add x to it if more than 0

});

It seems like each() is better than filter() because we can filter by padding and increase it in the same scope. It’s strongly adviseable to replace '*' with the most specific selector you can afford to use.
