Question

css

https://monsari.ru/
When you click on the certificate and scroll to the end, when you exit Fancybox, the layout of the slider gets lost.
Has anyone met with this?
I tried to re-initialize the slider when closing the fancybox gallery, but the error remains.

Try these properties by toggle

// Focus handling
  // ==============

  // Try to focus on the first focusable element after opening
  autoFocus: true,

  // Put focus back to active element after closing
  backFocus: true,

  // Do not let user to focus on element outside modal content
  trapFocus: true,
