Easier by not always. 
I still have not been able after all this time to get my Unifications images to line up with my code examples on this page. The problem is that these sites allow for a limited set of HTML for security reasons and I find that to do what I need requires using raw HTML and features of HTML that are not allowed. For Discourse it seems their parsing of HTML can not pass what I consider safe HTML. I did see a post on the Discourse forum that might work but after so many failed attempts I just don’t try any more as it will most likely fail.
However having failed in so many ways I do know some tricks that make more variations of markdown more portable.
