Page with margin: auto applied to .item (item div class) to
horizontally center. .item max-width is set to 800px for testing
purposes. .container justify-content is initialized to "initial" With
these settings, reducing window width does not result in left side
cut-off/clipping problem. So problem seems to get solved with this
fix.
Setting container flex: justifyContent to "center" creates the left
side cut-off/clipping problem!
