Tribute Page - No to Pineapple

Just finished my tribute page. It’s more a tribute to an ideology than a person, but I think it still ticks the boxes:

One thing I can’t work out is how to remove the spacing between the header and the start of the body. I want to to join smoothly like it does with the footer at the bottom. What am I missing?

Just add a top margin to your body.

      margin-top: 50px;
