margin directive not working

Describe the problem

When I use the margin directive

```{margin}
some content
```

I would expect the content to appear on the side, but it appeares in the middle, just like normal content.

I need to get my hands on a windows box.

I typical use wsl if you’re at all familiar with that. It might be a good way to get the latest working for you. I really like working with WSL (particularly since WSL2) for programming work.

@mmcky thanks for your efforts!

Looks nice with the margin.

it also looks like you’re not getting the LHS table of contents either.

I have intentionally collapsed the LHS table of contents (because I wanted to create some space for a wider screen, in order to make the margin appear) - but unfortunately this measure didn’t make the margin appear

This shouldn’t be required. I am running python=3.8 but I am using os x.

I think with windows and python > 3.7 there is some issue (see Point 2. here), that’s why I have downgraded python from 3.8 to 3.7

Do you happen to use anaconda for your python environment? Perhaps you could try that distribution as that is the environment I use.

Yes exactly: Anaconda navigator 2.0.4 and conda 4.10.3

Hmm strange, sounds to me, like this is really something with my windows?
