Code block line/text highlight

Developer help
1

Hello.

I would appreciate any input from you guys.

I set up the ghost blog a few months ago and enjoying every bit of it. One of the things I couldn’t get it to work is text/line highlight in the code block.

I followed this link and enabled syntax highlighting using PrismJS. https://ghost.org/tutorials/code-syntax-highlighting/

I mainly add Cisco CLI outputs which don’t have any syntax highlighting. I was wondering is there a way to add them? For example, if the code is:

set protocols pim interface ge-0/0/0 mode dense
set protocols pim interface ge-0/0/1 mode dense
set protocols pim interface ge-0/0/2 mode dense

Can I highlight a single line or make the word ‘protocols’ bold or a different colour?

Sorry if this is a silly question.

Thanks
