Online css for rmarkdown?

[teleopsis]

Simple question: is it possible to use an online css file (e.g. on github) for rmarkdown? I find that neither adding a URL in the header nor adding something in the body along the lines of

<style type="text/css">
@import url("URL");
</style>

Seems to do anything

Why not use the css argument often included with the format function ?

output:
    html_document:
        css: url of your css

did you try that already ?

Hi, thanks for answering. I tried that and couldn't get it to work... however, I have now found that it does work but only when the .css file is not on github. A bit of digging and it seems that there is something to do with the way github stores files with jekyll that affects how the links work. Or something.

Thanks again.
