Hello,
I mean, the header has the indentation from below 40px so to the first section after the header you need to add “margin-top: -40px”

The main section with all content has a “margin-bottom 40px”

if your HTML block is for pre footer or footer, you have to add a “margin-top: -40px” to it.

If you want to remove this indent from below anywhere, you can use custom CSS code, in Theme Settings -> Custom CSS -> enter the code to the “Global Custom CSS” field.
Kind Regards
