I think you would have to use some kind of filter to look either for an #+attr_html or src-header argument, and modify the html output for that.

Hi all,

I was wondering if there's a way to distinguish between different kind of source
code blocks when exporting to HTML.

Specifically, I would like a way to mark certain code blocks in my Org file so
that those code blocks get a specific class in the HTML export. I can then style
them with some CSS to make them stand out visually. I know I can use special
blocks to get divs with a custom class, but I don't want to lose all the
benefits of code blocks...

I tried Google and the Org manual but I haven't been able to find anything on
this.

TIA
