Yet another custom theme for Jellyfin mediaserver created using CSS overrides. While a separate theme, it is built on top of my other theme, Monochromic. Therefore, please open any issues over there. Kaleidochromic is essentially Monochromic, but with another layer of overrides on top. This makes maintenance easier. Note that I maintain my themes to be compatible with whatever version of Jellyfin I am currently using. Which is usually the latest stable release. You can therefore assume that using the theme on older versions may not work, but also that if a new release breaks something, that I will fix it.
Check out my other themes, Monochromic, if you are looking for something a bit more dark and muted, or Novachromic if you are a light mode kind of person.
To use the theme copy paste the line below into "Dashboard>General>Custom CSS" and click save, it will apply immediately server-wide to all users on top of any theme they may be using. To remove the theme, clear the "Custom CSS" field and then click save. NOTE: Theme may not work when using reverse proxy, check the bottom section of this readme for more info.
@import url('https://ctalvio.github.io/Kaleidochromic/default_style.css');
- Themes EVERYTHING
- Bright, Transparent, Minimalistic
- Uses the same font as the JF logo everywhere
- Add-ons for an easy personal touch
- Customizable accent color
- Blurred backdrops
- Rounded look (optionally sharp)
- Two options for progress bars
- Works well on mobile
- More compact
- Smaller and squared cast info
This theme has some additional options, they can allow the use of a custom accent color, and more. These are added immediately after the default import line.
A different itempage to the default of the theme, more reminiscient of "vanilla" as it does not remove the backdrop banner.
@import url('https://ctalvio.github.io/Kaleidochromic/alternate-itempage_style.css');
The theme uses mask-image to fade out items below the top bar as you scroll. This works well on most reasonable hardware but struggles on some phones and especially smart TVs. This switches to a method without using mask-image, but foregoes the fade-out effect. I may switch to this method being the default.
@import url('https://ctalvio.github.io/Monochromic/improve-performance_style.css');Don't like my transparent view progress overlay? Use this to go back to the old style.
@import url('https://ctalvio.github.io/Monochromic/bottom-progress_style.css');This add-on turns the cover image on the mobile item page into a backdrop, since mobile on 10.7.0 has no backdrop for library items on mobile.
@import url('https://ctalvio.github.io/Kaleidochromic/backdrop-hack_style.css');Blue restores the default jellyfin blue shade for accenting.
@import url('https://ctalvio.github.io/Monochromic/jfblue_style.css');By adding this variable at the bottom, after the import lines, the rounding can be removed, reduced or increased. Variables should always be last.
:root {--rounding: 12px;}This is now integrated into the theme and requires no additional import line, and uses a variable same as rounding. Use any RGB color picker to find the value for any given color and enter it. Variables should always be last.
:root {--accent: R, G, B;}
When using the Nginx Reverse proxy config from the Jellyfin docs the theme will not work by default. (If you are using the subpath config, you can ignore all this.)
Because the config includes Content-Security-Policy which reduces risk of XSS, you need to add the URL from this repo and the fonts to the list of allowed external sources.
In the nginx config you should change the
add_header Content-Security-Policy ....
to:
add_header Content-Security-Policy "default-src https: data: blob:; style-src 'self' 'unsafe-inline' https://ctalvio.github.io/Monochromic/default_style.css https://ctalvio.github.io/Monochromic/jfblue_style.css https://ctalvio.github.io/Monochromic/jfpurple_style.css https://ctalvio.github.io/Monochromic/bottom-progress_style.css.css https://ctalvio.github.io/Monochromic/customcolor-advanced_style.css https://ctalvio.github.io/Monochromic/improve-performance_style.css https://ctalvio.github.io/Kaleidochromic/default_style.css https://fonts.googleapis.com/css2; script-src 'self' 'unsafe-inline' https://www.gstatic.com/cv/js/sender/v1/cast_sender.js https://www.youtube.com/iframe_api https://s.ytimg.com worker-src 'self' blob:; connect-src 'self'; object-src 'none'; frame-ancestors 'self'";
If you don't do this the theme will simply not load (reverts back to default theme) and the browser console will spit out an error. Even if you paste in all the CSS, the font will still not load since it is loaded from an external source.
Thanks to LickABrick for discovering this, and submitting instructions on how to fix.
