Can you format text in Graphy?

Hi – wondering if anyone knows if I can format text the way I want in the Graphy theme?

I am running a site on Graphy (the free version) and would like to be able to use spacing and indents in posts. This is because some of what I am publishing is poetry that has unusual spacing in the text.

However, when I have tried doing this in edit mode, while it looks like it has worked, when I publish, the text reverts to standard formatting….

Any tips greatly appreciated

Cheers

Steph
