-**Note:** This component is intended to be a full-width section of a page, with

-don't place Split inside another `mzp-l-content` [container](content-container).
-The nested spacing will get weird.
+By default, Split is intended to be a full-width section of a page, with an
+outer container that spans the width of the viewport. Split has its own inner
+container to define its content width.
+
+If you need to nest Split inside another container (e.g. `mzp-l-content`), add
+the `mzp-l-split-nested` class to the outermost element (`mzp-c-split`). This
+removes the inner container's max-width and padding so it fills the parent
+container without doubling up on spacing.
