Thank you for your prompt reply.
It is very informative. I will try to devote myself to it every day.
I learned a lot from this part of your words.
Thank you very much.
I am still a beginner, but I have a question.
I would like to eliminate the blank space between the childbox and the footer when the childbox has finished scrolling.
Yes, this is what I was looking for!
I apologize for the inconvenience.
I forgot that I was using it in combination with smooth-scroller. So that was the cause.
Thank you very much!
I'm a beginner. I am having trouble with IE11 as soon as possible.

The above code is causing an error in IE11. Is there a workaround for this?
