I recently found scrolling the solution page is somewhat arkward, then I realize it is because the code block has a scrollbar, like this one:
https://leetcode.com/problems/median-of-two-sorted-arrays/solution/
If you move the mouse into the code block and scroll down, when the code block reaches the bottom, without any other mouse event, scrolling further will do nothing, instead of scrolling the page down. This is really awkward, you have to move and scroll the mouse a lot at the same time to successfully view both the code and the page.
A better way is simply get rid of the code block vertical scrollbar.
