I saw your project. there are a few issues:
First of all, you need margin and padding for the overall page. you reset the default values but now you need to adjust margin and padding. you can do this with
margin: 30px 8px;
for the main section. Assign this to the outer div or main.
2. You need text-align and line height for all the parts these are universal CSS values. So put them in the body
You also need to change the font family and font size, plus make the tribute page responsive. use media queries for that. @kambajuliet10 hope this helps
