wrap <div class="attribution"> in a footer tag to fix the accessibility issue.
you forgot to give the body a background-color. Each button must have a font-color that is the same as the background-color of the its div a font weight of 700 and a background-color of transparent. what you have now is the hover effect of the button.
Increase the padding value for .part-1,.part-2,.part-3 in the media query for smaller screens.
Use rem or em as unit for the padding, margin, width and preferably rem for the font-size for more on CSS units watch this https://youtu.be/N5wpD9Ov_To
