What is the difference between onmouseover and hover in CSS? onmouseoverhover

They are the same because:
It is triggered when the mouse is down.
They are different because:
Onmousemove is in javascript. It can trigger js commands, but hover cannot. hover is only a class of css styles and can only define styles.
For example, if you move the mouse over to implement an operation in the pop-up window, you need to use onmousemove. There is no way to use hover's css definition. Unless js is called in css, it will be troublesome.

 

In normal use, if you only want to display the style, you can use the pseudo class of CSS. If you need to change it dynamically, select js events.
