Can you create a corner radius for a footer

I was able to get the header rounded with the code below. I tried to copy and change it to footer or footer.sections and what is produced was nothing like the header.  I don't know what element I should be targeting and looking in inspect I only see the words fluid-engine with numbers.  I would love to be consistent with the rounded corners but if it can't be done I can go back to being square.  Thanks.

.header {
  margin: 0px;
  border-radius: 20px;
  border: 2px solid #FFC0CB;
}
 

You can use the section divider: 

Apply the divider to the section directly above the footer.
