Maybe a nice toy for your theme, too.

Hello @wessamlauf,

you seem to be a big fan of transparency effects, too. So maybe this is something of use for you:
My own theme repo with some more trickery hidden inside

Maybe you still remember the "Animated Background Addon" from Villhellm (R.I.P.) some years ago? (His Repository for original and My Fork for the one bugfix that fixed it for a very short period)
Well, as this broke way too often and was completely dead after he could not maintain it anymore because he is no more, I made my own way to get movement into my background of HA.

And after I got things working on EVERY page some time ago I thought that it might be good enough to show you, too. I have my own theme in use by default, which is a modified version of "yourname" by Nihvel as it was a wonderful base to use with all those transparency effects in place. Since then I added quite some stuff I personally liked except the trickery to get animations in the background of course.

But from time to time I check out what themes I find on HACS that are not just some lame and boring palette swaps with nothing innovative to show at all, but at least a bit more. And a while ago I found your work. I liked it immediately and even better.... It almost works out of the box with my animated backgrounds. Well... as long as your chosen backgrounds are not too bright :D But this kept in mind and you get this:

frosted-glass theme with some tricks taught

Don't get me wrong here, I don't wanna make PR for my theme. (That's why I made the video with your's to show what it looks like using your theme with the script!)
I just thought that from transparency fanatic to transparency fanatic it might be something you personally could like and put in good use. I am sure some people would complain that a background image is way too heavy for mobile use. Of course this solution is nothing for such users as we are talking about loop playback of MP4 files here. But I have unlimited data and I love to put it in use for some eye candy 🗡️

And if some ppl want to use it with restrictions for mobile devices, there is already a filter in line 37 called:
const slowDeviceUserAgent = "Kindle";
There you can choose another string to check for inside the user agent and cause a single frame loading only for anything mobile for example.

Looking forward hearing your opinion and maybe experience reports using it :D

And here for the most recent news:
Luckily the new HA 2026.2 version is different regarding sidebar transparency and my modification to keep it distinguishable is not needed in the previous form anymore at all. A less invasive solution now is directly inside my theme file and thus the script is easier to use in a universal way for other themes as it now has no theme specific mods inside anymore. I wonder if I try to find a nice solution for the not transparent sidebar in your theme, but as it's a design decision I think I will keep it the way it is right now.

Have fun tinkering with the new script version. Btw... there is a styles.js and a styles_multi_event.js these days. One is a minimal version with only one special treatment for a specific page and the multi event one is checking for other pages like settings and development tools and gives them different backgrounds compared to the original solution.

I checked the results with frosted-glass, too and did not find any fun breaking problems at all. So I think I will add this theme to a still to be created list of supported themes when I upgrade my theme repo the next time. Your theme looks way too good to not tell others about it... I am thinking about splitting off the script from the theme repo, too... It was meant for my theme only long enough and there are too many nice looking themes that could profit from using it, too. So it seems a bit... wrong? to keep it inside my own theme repo...
