jQuery, get width of one element and apply to another

Question

Is there a way that I can get the width of one element .container for example and apply it to another .item for example?

My layout is responsive, hence why I can't just give .item a fixed width value.

Answer 1

Like this -

$('.item').width($('.container').width());
