[Help needed] Jellyfin Background CSS and Show Header Images

[Pyroptical]

Hihi,

So just really got into this today and really happy with the look ive managed to achieve, bar one thing. Basically i've applied a nice background image via CSS, and it looks great on all the main menu pages, but as soon as i go into a show or an episode it covers up the header image, instead of the bottom of the page. would love some input. 

Code:

@import url('https://cdn.jsdelivr.net/gh/CTalvio/Ultrachromic/jf_font.css');
@import url('https://cdn.jsdelivr.net/gh/CTalvio/Ultrachromic/fixes.css');
@import url('https://cdn.jsdelivr.net/gh/CTalvio/Ultrachromic/base.css');
@import url('https://cdn.jsdelivr.net/gh/CTalvio/Ultrachromic/accentlist.css');
@import url('https://cdn.jsdelivr.net/gh/CTalvio/Ultrachromic/rounding.css');
@import url('https://cdn.jsdelivr.net/gh/CTalvio/Ultrachromic/header/header_transparent-dashboard.css');
@import url('https://cdn.jsdelivr.net/gh/CTalvio/Ultrachromic/login/login_frame.css');
@import url('https://cdn.jsdelivr.net/gh/CTalvio/Ultrachromic/fields/fields_noborder.css');
@import url('https://cdn.jsdelivr.net/gh/CTalvio/Ultrachromic/cornerindicator/indicator_corner.css');
@import url('https://cdn.jsdelivr.net/gh/CTalvio/Ultrachromic/type/dark_withaccent.css');

@import url('https://cdn.jsdelivr.net/gh/CTalvio/Ultrachromic/progress/floating.css');
@import url('https://cdn.jsdelivr.net/gh/CTalvio/Ultrachromic/effects/glassy.css');

/*Accent and rounding*/
:root {--accent: 200, 90, 255;}
:root {--rounding: 12px;}


.backgroundContainer {
  background-color: rgba(0, 0, 0, 0);
  background-image: url('https://images-wixmp-ed30a86b8c4ca887773594c2.wixmp.com/f/9b521ad9-d3af-409a-9f5c-d1df13e0f365/di1hris-c3da11ee-4f13-4c27-98b1-546debe9b8a1.png?token=eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJzdWIiOiJ1cm46YXBwOjdlMGQxODg5ODIyNjQzNzNhNWYwZDQxNWVhMGQyNmUwIiwiaXNzIjoidXJuOmFwcDo3ZTBkMTg4OTgyMjY0MzczYTVmMGQ0MTVlYTBkMjZlMCIsIm9iaiI6W1t7InBhdGgiOiJcL2ZcLzliNTIxYWQ5LWQzYWYtNDA5YS05ZjVjLWQxZGYxM2UwZjM2NVwvZGkxaHJpcy1jM2RhMTFlZS00ZjEzLTRjMjctOThiMS01NDZkZWJlOWI4YTEucG5nIn1dXSwiYXVkIjpbInVybjpzZXJ2aWNlOmZpbGUuZG93bmxvYWQiXX0.M-JhEVJZTozFd-PLLHF4r3hqdelbjou6Nre5sxZAxo4');
  filter: blur(0px);
  background-size: cover;
}

this is my code as of right now, most of it is from ultrachromic, but with a bunch of testing I've found that those are working as intended, its just the code snippet i got from the official Jellyfin css page that giving me greif.


Main menu looks great,  but this is how my show page looks
  




And this is the header image i want it to show with the css disabled, and a quick photoshop job of roughly what im aiming for
 


Thanks so much for taking the time to read, and thanks in advance for any help 💜


So quick edit:

i've managed to figure out how to apply the background to the bottom of the page, just need to rid the top half
