Website with dropdown menus built with HTML CSS and vanilla JavaScript

This is my first junior level challenge so please don't expect it to look exactly like the original😂 . I'm still really proud of the result. Really had the hardest time working on those dropdown menus. Its cause I don't really know any JavaScript lol. I had to use stackoverflow. I also had a hard time resizing items to look like the original and just resizing in general. The hero image took me two whole days just to make it look similar idk why.

Questions: How could I improve my dropdown menus in terms of size and sizing? How could I improve my JavaScript for the dropdown menus? How could I resize my hero image and body content better?

Let me know anything else I can improve☺️
