Sure, apply a background to #secondary in your child theme or Custom CSS plugin.
It doesn’t work correctly or as it expected. Please have a look at the attached screenshot.

It left all the bottom content without background.
Edit: I gave
#secondary {
clear: both;
padding-bottom: 50%;
padding-left: 0;
padding-right: 0;
padding-top: 50px;
background: #FAFAFA!important;}
and it seems fine. Maybe…
try setting
overflow: hidden
@romuloctba it worked and I believe it’s a more “correct” solution than my “padding-bottom”. Thank you very much.
