Canvas rewrites my HTML (badly). Is there a way to suppress Canvas's HTML rewriting?

Hi,

For some time now I have known that Canvas 'rewrites' any HTML you enter in it's 'raw HTML' edit facility. There are too many problems with this for me to even start listing them. Hence, the short version: is there a way to suppress Canvas's rewriting of author-entered HTML, i.e., a way to tell it to accept entered HTML 'as is.'

To my knowledge there isn't a way.  I know that only certain html is allowed and that is one reason some stuff get's re-written.  There was a html whitelist document but I'm having trouble locating it.

I know it can be frustrating but I also get why Canvas wants to limit some of what is allowed and "correct" some html to be formatted how it wants.  I have a case open right now about a course where the link validator tool won't complete and apparently it's due to some bad html on one of the pages.  Point being that bad html can break functions so trying to keep it "clean" as much as possible probably helps some with that even though it can be annoying for power users.

Hi @reitsmar and @rmurchshafer 

Apparently, someone on the Canvas engineering team had a problem with the term "Whitelist"; so in typical Canvas fashion, they changed the name from something everybody was familiar with to something nobody but their own engineers are familiar with. This makes searching for guidance so dang much fun! Not!

You can find the most recent whitelist at, Canvas HTML Editor Allow List PDF

Enjoy,
