What information was incorrect, unhelpful, or incomplete?

In the content-section table, the header is hard to distinguish from the body because they have the same font-weight—is this intended?

What did you expect to see?

Do you have any supporting links, references, or citations?

 th { 
-  font-weight: var(--font-weight-normal);
+  font-weight: var(--font-weight-bold);
   text-align: left;
 }

Do you have anything more you want to share?
