Responsive Intro Section with Dropdown Navigation

Hello Pogen, good work here, I just would like to suggest the following. When manipulating the DOM is a best practice do not set all the styles values directly by assignment operator. In small projects you can keep track, but the bigger the projects it gets the more complicated will be to keep separated JS and CSS.

Instead of this: document.getElementById("sideNav").style.width = "60%";

Use this: document.getElementById("sideNav").classList.add("someClass")

In your CSS this class should look like this someClass:

.someClass {
   width: 60%;
}

Also I would like to point to the Frontend Mentor report that is generated after you submit the challenge. There are good hints related to HTML structure and Accessibility.

Hope this is useful and happy coding!
