Page jumps to the top with Fancybox 3?

Question

css

Hi everybody! Connected fancybox 3 for modals. On opening the page jumps to the top, on closing it jumps back to the link. Found a solution from a previous version of Fancybox, didn't help
Old solution:

html {
  font-size: 100%; 
  overflow-y: scroll; 
  -webkit-text-size-adjust: 100%; 
  -ms-text-size-adjust: 100%;
}

$('.image').fancybox({
  padding: 0,
  helpers: {
    overlay: {
      locked: false
    }
  }
});

I do not know where to dig. Maybe someone similar?

Answer 1

There was such a problem due to the fact that the content went beyond the container. I set overflow for these blocks and the problem was solved (it was on a fixed layout, it's always good with adaptive)

Answer 2

html probably has height: 100%
