Zonelets CSS issue - ☔︎ ∙ I need Help!

Hello! I'm currently trying to add a Zonelets blog to my neocities page. I successfully inserted the Archive HTML Into my Site's existing format, but I'm struggling with post pages.

When I try to direct the post page to a CSS file from the Zonelets theme pack, it won't recognize it, and I just get a plain webpage. The post file, and the CSS file for zonelets posts are both in the /posts folder on my neocities page, and I pointed the HMTL to the appropriate CSS file, but so far nothing is working. Any help would be appreciated! Thanks!
