Use SW Pillar Section when you need image, video, form, or other content beside text in a side-by-side layout.
Use SW Pillar Section when the layout needs content in two columns, such as an image on the left and text on the right. The module is meant for side-by-side sections and stacks on mobile.
If the media should sit above the text in a simple stacked layout, use SW Text and Media for new content or SW Image & Text when working with an existing page that already uses it.
