Hi Rose,
not sure why the same issue has opened into 2 tickets, one is handled by Tony. https://www.8theme.com/topic/modules-width-adjusts-itself-when-scrolled-on-cart-page-2/#post-357634
When i removed the code you found, it works, but the width is way to big than I wanted it to be, that was the reason i added the code at the first place.

In this case, can you advise how to adjust the width to match with my other pages?
FYI:
Customizer > General /Layout. My Site width is set to 1170px
Elementor > Site Settings > Layout, Content width is set to 1140px.
