How to make background move slower than text in Skrollr?

Question

tIt seems that I did as it is in example here but my background moving faster than text. What did I do wrong?

My HTML:

<div id="loader-bg" data-0="background-position:0px 0px;" data-100000="background-position:0px -50000px;"></div>
<div id="skrollr-body">
    Content text...
</div>

Answer 1

The demo uses background-attachment:fixed to get full control of the movement.

Answer 2

Maybe you forgot to set the class attribute on your loader-bg div

class="skrollable skrollable-between"
