I am playing around with some of the sites from the site library in order to understand how things were constructed. I have installed a copy of Wordsmith and have an issue with the single blog post pages. By default these pages have no sidebar but the Blog Archive page does have a sidebar. My aim was to have a sidebar on the single posts too so I used the customizer via Layout>Sidebars>Single Post Sidebar Layout and changed the setting to Content/Sidebar.
This did add a sidebar but for some reason both the main section and sidebar on single posts are narrower than the same sections as seen on the archives pages. Is there another setting I need to tweak
