Select an element that doesn't have a background set

Question

Using jQuery, I need to select all elements that do not have a background color or image defined, and apply at least a white background to it.

Answer 1

If you know which specific elements you're looking for you could do something like this:

var els = $('div');

els.each(function(idx, el){
    if ($(el).css('background-color') == '' || $(el).css('background-image') == '')
    {
        $(el).addClass('white-background');
    }
});
