Hello @tommybarber,
Assuming that you are trying to change your website layout to “boxed” layout, Education Hub Pro theme already has the feature to switch the layout of your website.
To change your website layout to boxed please go to your Admin Dashboard > Appearance > Customize > Theme Options > Layout Options > Site Layout and choose “boxed” option. This will change your website as well as the blog page layout to boxed layout.
If the above steps does not resolve your issue, please explain further your issue with possible screenshot and site URL so that we can better understand the issue and find a precise solution.
Hope this helps,
Best Regards !!
