jQuery & CSS - Remove/Add display:none

To hide the div

$('.news').hide();

or

$('.news').css('display','none');

and to show the div:

$('.news').show();

or

$('.news').css('display','block');

jQuery provides you with:

$(".news").hide();
$(".news").show();

You can then easily show and hide the element(s).

In JavaScript:

getElementById("id").style.display = null;

In jQuery:

$("#id").css("display","");
