[jQuery] addclass() only works with the first of the matched divs

[Alexandre]

Hi,

I'm having an annoying issue with addClass()

I'm trying to find all divs with id name '#moldura_slides' and add the
class '.horizontal' to each one of them.
The problem is that only the first div matched gets the class. The
others are just ignored and don't get it.

$(document).ready(function()
{
     $("#moldura_slides").addClass("horizontal");
});


Looked for a solution everywhere and tried other ways of doing this.
Nothing worked. Any ideas?
