CSS Problem in Editmode

Hi,

i found this

Silly example markdown note:

---
cssclass: [redH1, blueH2]
---

# Test H1

## Test H2

Silly example CSS snippet:

.redH1 h1 {
  color: red;
}

.blueH2 h2 {
  color = blue;
}


that already helps well .

what can I do so that the colors also appear in edit mode?

thanks a lot
