Change font size for all inline equations R markdown

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

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?

You could add this to your css: .math {font-size: small;} – Peter H.
I'm not too familiar with the css settings, I tried this: --- title: "Title" output: html_document: css: .math {font-size: small;} --- which resulted in an error "Error in yaml::yaml.load(string, ...) : Scanner error: mapping values are not allowed in this context at line 4, column 26 Calls: <Anonymous> ... parse_yaml_front_matter -> yaml_load_utf8 -> <Anonymous> -> .Call Execution halted" – mr3543
add this after your yaml <style> .math { font-size: small; } </style> – Peter H.
That did it! Thanks so much – mr3543

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>
