My portfolio page freecode

Tell us what’s happening: I got hitched at the eleventh question of the portfolio page.

Your code so far
#welcome-section {
height: 100%;
background-position: center center;
-webkit-background-size: cover;
-moz-background-size: cover;
background-size: cover;
-o-background-size: cover;


that’s my code but i keep having the error message that the #welcome-section is not equal to the viewport.
