My apologies - I didn’t catch that in the screenshot. When I entered in my code, I had missed the question mark, and got the same complaint from the linter. Replacing it helped me.
But now that I have looked at your screenshot, I can help! Check your code for each of those lines (the embedded-opentype line); it looks like you’ve misspelt “embedded” in each tag. The first one needs an extra letter ‘d’, and the other needs the whole word, instead of just ‘embed’.
I hope that fixes it!
