Awe! Glad I could help!!! You’re off to a great start with this!!
A little something I saw… be mindful of how you use your h1, h2, h3 etc tags… they are not styling tags, but h for header header tags, like for the title of a section …but you are are using them inside of your ul (unordered list).
Consider, if your website needed a page of contents, the header tags would be the chapter titles for each section.
