how to make the arrow keys and space bar not force my webpage down?

Question

我制作了一个游戏，并且我使用箭头键移动和空格键进行拍摄，并且每次我按下向下键或空格键时，它都会一直将其压低到网页底部，是否可以将CSS修改为使它专注于游戏div标签而不滚动？

You are failing to cancel the event. If it's an inline event, just return false; at the end of it. If it's done with addEventListener , call Event .preventDefault() and return false; .
