Hi, can someone tell me how to add additional CSS to replace the background of a section? I am trying to recreate my website in Divhunt. This is my current website https://ahcrypto.com

Hi Scott, which section are you talking about exactly? Not sure what you want to achieve.

Hi, I mean the hero section, below the nav bar. I want to add the code for a moving background effect in that section, then style the section like the bento shape like the Astana breeze theme from Divhunt

I can also send you screenshots if you need me to, and if it’s better to use the template from Divhunt then edit it, I can also do that. I was just building it from scratch.
