I couldn’t find an example so here is mine…
source-view:
.markdown-source-view.mod-cm6 .cm-hashtag {
color : blue;
}
preview:
.tag {
color : red;
}
Bonus:
only hide the tag #important:
.tag[href="#important"] {
display: none;
}
you can edit these commands to hide tags or change color of tags or change fonts ect…
would be nice if someone could figure out how to do this [href=“important”] in source mode…
