Perfect, thank you so much, that was it! That solves it for me
just for the sake of others who might find this post.
Aparrently it’s also possible to define it like this:
.CodeMirror-cursor {
background-color: #ff0000 !important;
opacity: 60% !important;
}
in the case of this code it’s needed to put !important
like you said!
Thanks a lot for the help!
Update:
this code would change the cursor even when it’s not in vim-mode
to keep in only in vim mode the .cm-fat-cursor .CodeMirror-cursor
is needed
