Why did he apply the float to only the col class and not individually to primary and secondary?
In my solution, I applied a float left property to primary and float right property to secondary. That made more sense to me, because you aren't supposed to apply the float to the specific columns?
If you apply a float: left to col in general, then that would mean both columns would be floated to the left, which isn't what we want. We want one to go on the left and the other to go on the right.

The float left to both will work in a way where it push the first column to the left, then the second column against that the first one to the left as well. Giving the same result with less code. Which is always good.
