[jQuery] :last-child problem

[poncjusz]

Hi,

I've got strange problem with :last-child selector, my html structure:
<div class="box-full">
    <div class="info green">
    </div>
    <div class="info green">
    </div>
</div>

and jquery script:
$(".box-full .info:last-child").addClass("last");

what is strange that
$(".box-full .info:first-child").addClass("last");
works perfect!

thanks in advance

Tomek
