Should buttons have hover state?

Hover: The hover state is specific to web design as mobile devices don't typically support a hover interaction. This is the state that a button will be in as the mouse cursor rolls over the button on the screen.

What is hover state button?

the appearance or behavior of a button or other control while the pointer is over it but the item has not been clicked or dragged; most often used to hilite buttons as the pointer moves across them to indicate that they are clickable or to show labels or instructions indicating what the button will do.

Should hover states be darker or lighter?

Darker seems more natural. If anything, a physical button would appear slightly darker when you touch it because your hand is casting a shadow. Lighter (illuminated) might signal that the button is waking up at the moment it's needed, like a fog light, refrigerator light, or moving sidewalk.

Do buttons have active states?

When we click a button, the active state occurs in a very short time. Actually, this state is the time interval when we interact with the button. So the active state is not the selected state. To see it more clearly, hover over the button with the mouse and click the button and stay there.
