I have a sidebar on my blog posts and home page. I understand it should disappear when you get down to iphone-like widths, but it drops out in browser windows less than about 2/3 of my desktop screen. Please fix, or just tell me how to lower this threshold.
This is normal theme behavior and works as intended. The sidebar moves below the content at around 1024px screen width, which is a common responsive breakpoint used to improve readability on tablets and smaller screens. This will not affect standard laptop or desktop usage when viewed at normal widths.
Lowering this breakpoint would require custom CSS changes. While it is technically possible, custom layout modifications like this are outside the scope of our theme support, as the theme is functioning correctly by design.
