Change css of multiple elements

Question

I just want to know if instead

$(".element1").css('background','#000'); $(".element2").css('background','#000'); 

You can concatenate multiple elements so that they are affected by a single command, or if there is a more efficient way:

 $(".element1",".element2").css('background','#000'); 

Answer 1

CSS selectors always support unions:

 $(".element1, .element2").css('background','#000'); 

You can also add to jQuery element:

 $(".element1").add(".element2").css('background','#000'); 

All you need is a quick look at the documentation .

Answer 2

$(".element1,.element2").css('background','#000'); will fulfill
