Should display a large header "ACME Inc" (in file header.html) and a small footer "Copyright 2016" (in file footer.html).

Should display a cascading set of paragraphs included from each other (seven in total).

Should display a 404 error. Using CSS we color the content red based on the status. The exact nature of the 404 content depends on what the server returns.
