I am preparing a presentation with Marimo slides but my mathematical equations appear too small for the slides. I have tried to add the cell:
import marimo as mo
app = mo.App(css_file="custom.css")
referencing a css file with the contents
.katex {font-size: 2em!important;}
but this doesn't change the font size. I can edit the font-size in an inline style attribute but this leaves the subscripts and superscripts at their original size.
What is the correct way to increase the Katex font size in a Marimo Notebook cell?
