CSS2d not showing and I am not sure what am I missing?

I am trying to use css2d as show below
and using v0.135.0

and in Renderer

it is surely adding on DOM and updating translate value when I move

and Yes I did add in CSS for .label

But no result in canvas.
Here is the complete code : CSS2D - CodeSandbox

turn out I was appending to canvas rather than container

Now its appearing but I am not able to use my orbit control.

I think is should be z-index issue or something . I am not sure.

It was a z-index issue . Now its solved.
