Side bar..works on on not both

in ‘knottydog’ you have set the #page width to a fixed 1000px; in the parent theme style.css (plus possibly other modifications) –
while in ‘jaynehemm…’ you have left the original max-width: 1000px;

Thanks, but where did I do this? In the child css?

Yep in the Child Theme style.css file

where did I do this?

unfortunately, you have edited the style.css of the parent theme Twenty Eleven directly in ‘knottydog’ – this makes it very difficult to re-trace the edits.
I guess, you might heve removed some of the @media responsive styles to keep the sidebar in its position when viewing on small devices.

general instructions for customisation in a child theme for keeping the sidebar in its position in small browser screens: https://www.transformationpowertools.com/wordpress/twenty-eleven-sidebar-adaptations-for-hand-held-devices

I have found that the style.css was edited in the KNOTTYDOG.COM site, but for now it works. The style.css is VER 1.5

The jaynehemmerich.com site still does not work. I found that the style.css in this site is VER 1.8

I compared the two style.css line by line and found the 2 oe three place that the width was changed…BUT I also found considerable changes in the /*RESPONSIVE STRCTURE*/

It looks like it has been completly redone…SO using style.css VER 1.8 by its self DOES not work
Adding the child theme with the changes that I thought would work..does not work

So any ideas what to do to make it work or revert to the old modifyed style.css

Thanks for any help
