Change font size for all inline equations R markdown

Question

I am creating a r-markdown file and using knitr to convert to HTML. When I inline an equation such as X_1,...,X_n \sim N(0,1) it gets converted to HTML output as this

.

The math text is oversized relative to the plain text font. I can correct this for a single equation with \small X_1,...,X_n \sim N(0,1). However, I would prefer not to type \small hundreds of times throughout a document. Does anyone know how to correct this with a single settings change or modification so it's applied to all math text in the document?

Try adding the following CSS after your YAML, or include it in an external CCS document. Pandoc automatically wraps inline math in <span> tags with class math. By modifying the math class, we can adjust the font size.

<style>
.math {
  font-size: small;
}
</style>
