Show/hide css/javascript code not hiding content properly in Chrome

Question

I've scowered this site trying to find a similar issue, but so far no luck. Hoping perhaps someone here would know the answer :).

I found this site that had show/hide scrolling code which seemed to work well enough for what I wanted. I've implemented it, and it works fine on Firefox. The scrolling also works fine on Chrome except for the fact that the videos in the "hidden" portion tends to show up in the top left hand corner. To trigger this, click on a different link (i.e. poetry, get involved etc) and click back to music, that's when it messes up. I've included the code in the header as well as the page for "music". I've used the same code in the poetry section, and no issues with the text. Perhaps it has to do with the iframe? Thanks so much!

Answer 1

Consider jquery?

$('.dhtmlgoodies_question').click(function(e){
    e.preventDefault();
    $('.dhtmlgoodies_answer_content').slideUp;
    $(this).next().slideDown(500);
});
