I’m looking to add some SSI elements to the HTML syntax theme and would love to know if it’s possible to extend the HTML syntax theme without having to include it into my package.
It’d require identifying a new tag
<!--# and elements (set, echo, include, etc) appropriately. But it all lives within HTML, a file is never pure SSI. Again, I don’t want to have to include my own version of HTML tags.
I’m familiar and comfortable working with JS and CSS, But I’m not sure where to start. Any advice would be greatly appreciated.
