Powerful, nicely working, stable plugin

The key question when installing the plugin is the two Frontend Settings parameter as described in the ‘Simple theme setup’ instructions: https://github.com/JoryHogeveen/off-canvas-sidebars/wiki/Theme-setup It can be adapted to almost any theme, but you usually have to touch the header.php and footer.php adding two lines of code. That’s why the advice to do that on a child theme. It can be issue when you have sticky header (fixed header) and want to scroll on the page. The header will not be fixed but moving when scrolling despite you use fixed header. In my case it was solved easily changing the Frontend Settings according to the plugin official wordpress page: Legacy CSS solution. Use basic CSS2 positioning instead of CSS3 transform with hardware acceleration. My advice is: read the documentation from the developer and you will be happy with this wonderful solution. Works well on mobile phones too.
