Can't remove white space between sections after using "make code from design" in Figma Sites

I converted my header into code so that it will follow any viewports’ screen size. However, there’s a space between the header and my next section that I can’t remove. I tried using the AI to help me remove it but it’s not disappearing. It looks fine on my workspace but it appears when I preview and it’s also present in my published website. Any ideas how to remove it?

• Other notes:
  • Header and the next section has 0 padding and margin
  • It still happens when I hide the next section (still a gap between the header and the footer) which leads me to believe the problem is in the footer

I’d also appreciate if you guys know any other methods to make a frame fullscreen for any viewport size. Thanks!
