You have to remember that in order to select a class you have to put a dot (.) before the class of that class, and to target a descendent of any element, or class, or id you have to put a white space between them. The final code the the three tasks is this:

/* Complete the challenge by writing CSS below */
header span {
  font-size: 26px;

.main-content p {
  font-weight: bold;

footer p {
  color: slategrey;

I hope that helps a little bit.
