Is it possible to achieve this specific layout using only Bootstrap 4?
+-------------------------------------------------+
| Navbar fixed on top |
+------------+------------------------------------+
| | |
| | |
|Column A |Column B |
| | |
| | |
| | |
| | |
| | |
| | |
+------------+------------------------------------+
| Fixed footer |
+-------------------------------------------------+
I need to ensure that Column A and B expand to fill the remaining space, covering the full screen without any scrolling at the body level. However, if their content exceeds the available space, I want them to scroll independently of each other - meaning scrolling in Column A should not affect Column B and vice versa. Additionally, how can I hide the scroll bars?
