Colour of an element changes when hovering over another one

[Cortile]

Hello,

I would like to make something similar to the page on this site: https://cigue.net/en/index/

So I noted that in the theme's css:
#scenography1:hover ~ #scenography2 {
color: black!important;
}

Then change the css class of my elements.

Only when I hover over the "scenography1" element the other elements do not change colour.

However, I tested it by replacing "Color" with a coloured background and it works. What's more, I succeeded on a test server that doesn't use the theme. So I guess the problem is the theme, but I can't put my finger on it.

Can you help me?
