@Shamama: unfortunately this still does not work for me.
This was your original code:
/* outliner for the outline */
.outline-heading-children{
border-left: 1px solid rgba(118,158,165,0.2);
border-radius:0 0px 0px 0;
transition:all 0.5s ease-in-out;
}
.outline-heading-children:hover{
border-left-color:rgba(118,158,165,0.4);
}
Does you new code replace all of this, or only the 1st block, or only the 2nd block?
