Plugin glues your website’s sidebar, making it permanently visible while scrolling.
By default, it uses “#secondary” css id under “Sticky Class” setting field and that should be modified for different themes to make it work. Don’t forget this, it’s a mandatory field.
Sticky sidebar plugin will work out of box with some themes which use “#secondary” id for sidebar by default such as: Twenty Sixteen, Twenty Fourteen, Twenty Twelve, Total, Flat Bootstrap and many more…
Plugin is localized (multi language support) and responsive (as far as your theme is). Advancement of this simple plugin is that increases usability of WordPress site since sidebar is visible most of the time.
