How to change background color for selected node?

[rohitkrishna094]

Let's say I click on some node, I want to highlight it in blue color or something as a visual cue for the user that they have selected this node. How do I add my own custom css for such a feature?

I was able to do this using

.rct-node-clickable {
  cursor: pointer;

  &:focus {
    background: #3399ff;
  }
}

For reference on sass file, check this: #294
