Current value of key style properties:
Set container flex: justifyContent=
item div: overflowX=
image: span-ws-pre:

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!


[Span without whitespace: pre:] This post is about the app/program, "Blogger Blog Feed to HTML Book" that I have currently published on https://bloggerfeedtobook.netlify.app/.
[Span with white-space: pre:] It should work with any Blogger blog. I have tested it with one of my Blogger blogs and some other Blogger blog.
