Your opening main is inside your h1 block. Blocks should not partially overlap, ever. They are either siblings or children. This is a hierarchy, not a Venn diagram of intersections and unions.

<!-- broken, overlapping -->
<element1>
<element2>
</element1>
</element2>

<!-- OK, they're siblings -->
<element1>
</element1>
<element2>
</element2>

<!-- OK, they're parent/child -->
<element1>
  <element2>
  </element2>
</element1>

Also, you have two closing main tags.
