Solution to the Social links profile challenge

Does the solution include semantic HTML?

Yes, you could improve it by wrapping the list of links in an ul element.

Is it accessible, and what improvements could be made?

Yes, maybe you could add a target for the links.

Does the layout look good on a range of screen sizes? Is the code well-structured, readable, and reusable?

Yes, the only downside I see is the use of html { font-size: 62.5%; }, this hack is not readable for other devs.

Does the solution differ considerably from the design?

Not really except some font-size and font-weight.
