Answer 1

Try clearing between divs

Answer 2

I copied three copies of your code and it was normal

The abnormal formatting is caused by your style file, you can only change it slowly by yourself

Answer 3

Style layout is not difficult. Look carefully at the width and height of your div to see if the div below is squeezed in. Your code only has a selector, and we have no way for you to tell.
