title: background images outside of a container css
body: <p>im trying to build a web layout that has a fixed width container. the design calls for background images to go outside of the container though, meanwhile still keeping the text of the divs within the container.  below is an image to show what i mean:</p>
  
  <p><a href="https://i.stack.imgur.com/0neJS.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/0neJS.png" alt="enter image description here"></a></p>
  
  <p>The black is the container, the red is the sidebar.  the content on the sidebar should stay within the container, but different sections of the sidebar have different background colors.</p>
  
  <p>any suggestions?</p>
