Blank space under my footer

Hi everyone, I am an inexpert Webflow user. In the builder, my footer appears as the last thing in the page, but when i go to the preview mode there is still some blank space under the footer. Can someone help me to make the footer the last element in my pages? Thank you.

You’re using display flex on the body which I would avoid, instead use a div and wrap everything for more flexibility.

A simple fix for your problem based on the way you’ve currently put it together:

  1. Change body to justify-content: center;
  2. Remove height from div-block-15 so it defaults to auto.
