What was the reason for the 2nd column STILL appearing below the 1st column after changing the display to inline-block?
I don't really understand how the margin space has anything to do with this. Technically, these inline-blocks should have been displayed horizontally, but I didn't understand the REAL reason for that as per the video.
This behaviour did not occur for the list items. When we changed the list items to inline blocks--they appeared side by side, but this wasn't the case here.

The "gutter" space between the columns is the reason they don't fit originally. The 50% width setting only applies to the elements themselves and does not account for the gutter space. So the total size is more than 100% until the negative margin is applied to consume the gutter.
All the list items combined still don't exceed 100% of the width, so they don't have this issue.
