Show your theme/style

[Drake97]

Hello,

Could you share how you have your Jellyfin configured visually and in style ?
I am asking this because I realized that I am looking for a good theme on the internet, that is nice, minimalist and user friendly, however, there are themes that have 3 good things and 1 bad, there are others that have one good and 3 bad and so on, I have not found one that has everything good.

What imports do you use with your Jellyfin ? Is there a possibility that you show images and/or links to the Custom CSS section to get some ideas ?

Thanks in advance

It's scyfin theme from loof2736 but some parts are edited to feel more consistent. I also removed the things I don't need like the codec informations.

I gave it a try and it looks amazing, good customization.
I did change the font to Jetbrains-Mono, which is a bit more to my liking, thanks

Hello, I liked the customization, especially the one of the subtitles, but I have a doubt, what parameter could I modify so that my media use the entire screen instead of leaving that space with nothing (marked with red crosses) ?



I mean that rows of 4 above and 4 below are displayed

thx in advance

[Iskelderon]

That usually happens if the containers are just slightly too big to fit another one. Make the value for the home cards slightly smaller until the row gets filled.

It's scyfin theme from loof2736 but some parts are edited to feel more consistent.

Thank you for sharing, but can I ask why there are so many CSS features not working on my Jellyfin? (Background, transparent style and so on, I have enabled Settings -> Display -> Backdrops option)

[bpawnz]

This theme is actually excellent.. good job!

I did some modifications to your theme and cleaned up some things a bit.. All though I 100% based it off the look you were going for.  If ur interested see below. I added some animations, mouse over effects, and colors in certain area.

Also do you know how to style playlist in grid format? I cant seem to make that happen?  just something i personally want for my collection

It's scyfin theme from loof2736 but some parts are edited to feel more consistent.

Thank you for sharing, but can I ask why there are so many CSS features not working on my Jellyfin? (Background, transparent style and so on, I have enabled Settings -> Display -> Backdrops option)

I prefer when background images are disabled so I didn't really considered them when making my edits. You might have to remove some stuff like the gradients or the backdrop container height.

I am running the linuxserver docker build and everything is working perfect. https://docs.linuxserver.io/images/docker-jellyfin

strange you are having differences. how are u currently deploying Jellyfin?
