Hey! There are actually a lot of platforms where you can build your site without knowing HTML/CSS. Some of them i've already tested, some just planning to do, but i will list here all of them so you can choose the one that will suit your goals better
1 — Framer
Basically it's like figma, but for websites
2 — Readymag
A lot of templates for different sites, but with some bugs.
3 — Cargo
Good if like brutalist websites
4 — Mmm
Simple tool for one page websites
5 — Ctrl
Haven't tried yet, but they seem nice
6 — Webflow
This one is a little harder than the previous ones, but maybe one day you would want to try something like that!
Good luck with creating your site!
