Site continues after the footer ends?

[Spectrum]

Hey everyone, the site I made was https://rustops.com/ using the template http://www.free-css.com/free-css-templates/page212/leslie-deniels and once I was done I scrolled to the bottom and the website continues after the footer ends. Does anyone know how to fix it? Any help is much appreciated  (I'm very new to html/css)

You are creating nested sections, instead of individual sections for each individual heading 'About RustOps', 'Our Pledge', 'Rules' etc

<section>
  About RustOps...
  <section>
    Our Pledge
    <section>
      Staff
    </section>
  </section>
</section>
      

Instead of

<section>
  About RustOps
</section>
<section>
  Rules
</section>
<section>
  Staff
</section>

You are also using multiple duplicate id reference of 'parallax', when only a singular unique id can exist within a page. This error would have been picked up by validating html at https://validator.w3.org/ .
