 ## Light Weight Modifier
 
-The default font weight for headings is normally defined by heading level. This modifier will change the heading to `font-weight.$light`. We do this to maintain the importance of headings without drowning out other content.
+For headings that are large in `font-size` but should have a bit less visual emphasis than others, the `c-heading--light` modifier will apply a lighter weight. You may use `b` or `strong` elements to emphasize key words or phrases within these headings.
