How do I hide the navigation on one page on my site (Rally template)?

Site URL: https://onebam.com/

I am creating a new sales page and I want it to be standalone, meaning, no navigation bar at the top. If people find my site and click around, that's fine, but I want this sales page to be just that, without buttons to take people somewhere else. Is there an easy way to do this? Currently the page is live but not linked in the nav. It can be found here: https://onebam.com/bizbootcamp

<style>
	.Header--top,
    .Mobile-bar--top {
      display: none;
    }
    body {
      margin-top: 0;
    }
</style>

For a specific page (adds to one page only). Pages -> Gear Icon next to the page -> Advanced -> paste the code above
