当你按下按钮时，按钮会上下移动，并且还会移动旁边的文本。我认为这与我在不同状态下绘制按钮有关，但我对CSS/HTML还不太了解，不知道该怎么办。这是这个暂停按钮的编辑版本。

如果你有更好/正确的暂停/播放按钮实现方法，那也可以。

  5. &lt;/div&gt;

The button moves up and down when you press it, and moves the text next to it as well.
I think this has something to do with how I am drawing the button in the different states, but I am new to CSS/HTML so I don't know what to do.
This is an edited version of this pause button

If you have a better/correct way of doing a pause/play button, that would work as well.
