CSS transitions allow changes to CSS properties to happen gradually over a specified period of time, rather than immediately. This can be used to create simple animations such as color changes, size adjustments, or positioning.

To create a transition, you define which properties should change, the duration of the change, and the timing function (for example, ease, linear).

Syntax-

element {
 transition: [property] [duration] [timing-function] [delay];
}

Example-

Creating a button that smoothly changes color when hovered,

<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<title>Change button color using css</title>
<style>
 .button {
   background-color: blue;
   color: white;
   transition: background-color 0.5s ease;
 }
 .button:hover {
   background-color: green;
 }
</style>
</head>
<body>
<button class="button">Hover me</button>
</body>
</html>
