could you please maybe make your site more accessible to screenreaders?

Good afternoon y'all, I'm not trying to bother y'all and I hope this comes off friendly and respectfully, I really am just trying to learn and do my best, but I am a student and I just wanted to let you know that the blue highlighted words mess with screenreaders. Like, they just won't read those words, and in many cases that messes with people's ability to actually learn from the lesson, especially if you're trying to present to them a new term that they're going to have to remember and you've put it under the blue text that's supposed to have that little pocket of information attached but certain people can't access it due to needing to use a screenreader. Is there a way this can be fixed? I merely use screenreaders for my LPD since it's harder for me to take in read information as opposed to spoken information, but I have run into this a lot, and I can only imagine it's more frustrating for someone who is actually vision impaired and more heavily relying on stuff like that to have that happen so often. Any thoughts on this?

Thank you for your time!
