Did you know that you can add Widgets to this sidebar area?
Content added to this area will appear on every page in the site.
Note: Not all templates have a sidebar area like this, but most do.
The Row Layout Widget divides the available space in the row among each of the widgets it contains. If there are two widgets, each widget has 50% of the space available. If there are 4 widgets, each widget has 25% of the space.
In this case, there are two widgets in the row. An Image Widget and a Text Widget. On a tablet or larger display the widgets are displayed side-by-side, however on small displays the widgets display vertically to make it easier to read on smaller devises.
