If you are viewing this blog on a desktop computer, you can see an example of a sidebar on the right side of the page. The mobile version of this site places the sidebar at the bottom, below the main content of the page. In general, it is better practice to place your sidebar on the left side of the page, so that mobile users can access it without having to scroll all the way down.
Adding a sidebar to your site is quite simple: just start with the Columns element. Set it to 2 columns if it isn't already, and drag the divider in the middle over to the left. The exact proportions are up to you, but a good rule of thumb is to have the right column (which will contain the main content of your page) at least twice as wide as the sidebar column.
Next, you'll want to put something into your sidebar. Most people.ua.edu users employ a sidebar to group together sets of "nested" pages that don't appear in the main navigation bar at the top of the site. This allows visitors who use accessibility tools like screen readers to navigate more easily. To provide additional accessibility, use the Title tool instead of the Text tool to create your links - screen readers will give this kind of text higher priority.
Then, simply place the main content of your page into the right column, and you're finished!
