In fact, the key to this article is to use the hover pseudo-class. Here I will also give you a brief introduction to the definition and usage of css:hover.

:hover pseudo-class is to add special styles to this element when the mouse moves over it. This pseudo-class applies elements that are in a "hover state". Hover is defined as when the user indicates an element but does not activate it. The most common example of this is moving the mouse pointer within the bounds of a hyperlink in an HTML document. In theory, other elements could be hovered, but CSS doesn't define which ones.

Note: All major browsers support the :hover pseudo-class.

I hope this article will be helpful to friends in need!
