CSS布局仅在IE7中定位文本在图像上发布

So this layout is only causing problems in IE7. I'm trying to do a centered layout with 2 images around a video embed and have some text over one of the images. IE7 throws the text way over to the right. I'm not sure if IE7 is not handling the negative margin method for centering or some other issue.So this layout is only causing problems in IE7.
