Hi Armin!

well i'm trying use this scroll (you can check it on my tumblr: http://nunomaio.tumblr.com) on my website. i checked the code of the theme, and this is the scroll part, css:

.element {
background-image: url(someimage.jpg);
background-attachment: fixed;
background-size: cover;

i've tried it but it doesn't work, can u help me?
