Bootstrap modal: background jumps to top on toggle

Question

I have a problem, with a modal. I have a button on a page, that toggles the modal. When the modal shows up, the page jumps to top.

I have done everything I could to

Answer 1

After reading dozens answers over several hours I copied the original code from the bootstrap file again and debugged step by step to see what caused that I always jump to the top. Because the actual latest version of Bootstrap 3 is showing the modal at the position you're at right now. I had found out that -webkit-transform: translate3d(0,0,0); and height: 100% in my css body-tag caused this behaviour. Maybe this helps some one.
