It says: ‘Comments can be written in Markdown.’
– Is it possible to use html tags to change the font size in the section comments ?
<span style="font-size:0.5em;">Text goes here</span>
I know I can use # to adjust the font size, but am just wondering if there are other ways.
I guess it should work - HTML is valid markdown, and we’re not doing anything fancy with the markdown parsing. Worth a try!
Thanks ! I tried that but failed. I ended up using 5 ‘#’ to get a smaller font size 
Do you have a minimal example? Is this in a module you’re writing or custom content or something?
I’m sorry. I must’ve done something wrong, probably didn’t pay attention to the ‘quotes’. And I tried it again, it works fine.

Hooray! That’s the best kind of bug!
