Stylus red style

Hello chess friend,

I want to have a special red style of the chess board. The preinstaled "red" style is not my favourite.

Also tried the plugin Stylus but didnt find a red Background image and could not edit the css.
Something like this code didnt work:
.olive .is2d cg-board, #top div.color_demo.olive
{
background-image: url("http://i.imgur.com/NmCnjQx.png");
}

Would appreciate if someone can help ;)
Thank you in advance!!

This works on lichess.org/tv for me:

cg-board
{
background-image: url("http://i.imgur.com/NmCnjQx.png") !important;
}

Pretty board image, BTW.

It work for some areas of lichess.
Somehow for analysis or puzzles the background is transparent/white.

In the "console" there is a error:
GET http://url....
net::ERR_BLOCKED_BY_RESPONSE

Is it normal?

thank you in advance!

@Bazinga87 I don't know if this answers your question but you can install of this styles: github.com/berserk-K?tab=repositories I can do a chess board for you and I can tell you how to correctly use them on Lichess.
I did some boards here: github.com/berserk-K/Lichess-board-background

@Bazinga87 I tried to play a game with this style:

cg-board
{
background-image: url("http://i.imgur.com/NmCnjQx.png") !important;
}

and it's working...
Are you using stylus?

@Krukulu for playing and watching games it works.

I just need it for analysis. It looks like lichess block this url for the analysis section :(

@Bazinga87 #3 I have the same issue with the puzzle board. My guess is that these styles are written using JavaScript, so they overwrite the pure CSS styles you gave to them. I didn't test, but using an add-on like Tampermonkey you can write them using JavaScript, with a small timeout. That should work.
