Jill Plescher, do you have an example of the HTML you are trying to change?
Also, apologies if I'm stating the obvious as I don't know how much experience you have, but have you utilized the "inspect" option in your browser to be able to view the page's HTML? It's super useful for learning how web pages are structured, and you can even use it to for reference when designing your own pages. I've found it very helpful!
Best,
Katie
