The follow example illustrates how you can configure sections of a page with background colors or images that run from the left edge of the browser to the right edge of the browser.  The background image position and size can be adjusted as needed through CSS.  You can also combine multiple background images for an individual section to achieve the look you need.

Note: To configure content to run from edge to edge, you must disable the Aside and then configure the main Section elements of your Article with a section layout.  If you use a Grid layout for the initial sections, the generated HTML sections will never reach the edge of the browser.
