How to remove site wide elements (announcement bar and footer) from a single page only?

I have a marketing announcement bar and footer that is on every page of my site. I also have landing / funnel page that is hidden on my site. I would like to remove the announcement bar as well as the footer from just the funnel page only. Anyone know how I can do that? Thank you!

Add to Funnel Page Header

<style>
  .sqs-announcement-bar-dropzone, footer.sections {
  	display: none !important;
  }
</style>
