Hi,
I thought I understood ;-) I tried to customize the hero-slider - because the falling dots remind me too much of snow. So I wanted to change the polygones to circles. I changed the coding in hero-slider.html.twig, saved it, recompiled everything but I still have the polygones...
I now read that you should copy the original file to custom - but that can't be the reason why it doesn't work?? :-)
Thx, Frauke
