Let’s also add these buttons to the first section.
Copy the div.apps-buttons with all the children and add to the section.banner-section .content.
Replace only large with small for platform elements
And immediately add the style for .platform.small: height 50px.

We’ll also add scrolling right away.
The section .banner-section must have an id about.
The first section .description-section must have an id learn.
The section .join-section must have an id download.

And add links to .nav-item-link: #about and #learn.
The .download-btn must have a #download link.
