W3C validate ?

Hi Carolina,

First, I would like to thank you for your work !

I am using your theme music as a base for mine, and I really like it.

I have 1 remark :
I try to validate the website with W3C
and it returns the errors bellow :

Line 134, Column 7: End tag for body seen, but there were unclosed elements.

</body>

?
Error Line 55, Column 21: Unclosed element div.

<div class=”wrapper”>

?
Error Line 61, Column 74: The aria-controls attribute must point to an element in the same document.

I don’t know if it is due to my modifications or not.
Could you please have a look ?
Thank you in advance four your answer !
