`:selected` styles not applying

[ceebs]

When I add custom styles for :selected, those styles do not apply when clicking on a node and I have not seen an example online where this functionality is working as expected.

Is there an example you can show how, when clicking a single node, we can change that node's colour?

Thanks!
