- the "Right Sidebar" of the Forum has 250px when viewing at a desktop.
- in mobile-view, the "Left Sidebar" at the RM has a width of 265px
- when viewing the "Left Sidebar" at the RM at a desktop, the width is 220px
I would suggest to make the width of all Sidebars towards 265px
This would also look nicer as the content in the Sidebars would not look as "packed" or "compressed" as it is currently.
