Why can't customers see the checkout button when cart is full?

Topic summary

A Shopify theme has a critical checkout issue: when customers add more than 3 items to their cart, the checkout button moves below the visible screen area and the page won’t scroll down to reveal it. This prevents customers from completing purchases.

Key details:

  • The cart container appears to have a fixed height or overflow issue
  • Screenshots were provided showing the problem (cart too tall, checkout button positioned just right/off-screen)

Current status:

  • A support representative has requested the store link and password to investigate and suggest a solution
  • The issue remains unresolved and awaiting further diagnostic information

When adding more than 3 items in a cart, it makes the cart too long and the “checkout” button moves off the screen, which means customers can’t complete their purchase.

The page won’t scroll down to expose any more of the cart.

Any thoughts?
