Thank you for your reply and the solutions provided.
Just in case you got me wrong:
I created a one row layout with a fullscreen carousel (fixed height: 100vH, filled slides) and text elements "on image".
Now I'm trying to change these elements (e.g. the site title) on a specific carousel slide (2) like this:
.slug-fullscreen
.lay-carousel-slide:nth-child(2)
.sitetitle span{
color: white !important;
}
Does this make any sense?
