      height: 200px;
      background: #eaeaea;
      transition: background 0.5s ease-in-out;
    }

    .box:hover {
      background: #ff0000;
    }

    @keyframes pulse {
      0% {
        transform: scale(1);
      }
      50% {
        transform: scale(1.2);
      }
      100% {
        transform: scale(1);
      }
    }

    .circle {
      width: 100px;
      height: 100px;
      background: #00ff00;
      border-radius: 50%;
      animation: pulse 1s infinite;
    }
  </style>
</head>
<body>
  <div class="box">
    <div class="circle"></div>
  </div>
</body>
</html>

In the above example, When the mouse hovers over the .box element, the transition effect of the background color will be triggered; the .circle element has a cyclic scaling animation effect. This makes the web page more lively and interesting.
