如何使用HTML/CSS使按钮可点击？它需要与标题一起居中放置在图像上

<div class="container">
  <img src="image.jpg" alt="图像">
  <h1>标题</h1>
  <a href="#" class="button">按钮</a>
</div>

.container {
  position: relative;
  text-align: center;
}

.container img {
  display: block;
  margin: 0 auto;
}

.container h1 {
  position: absolute;
  top: 50%;
  left: 50%;
  transform: translate(-50%, -50%);
}

.container .button {
  position: absolute;
  top: 50%;
  left: 50%;
  transform: translate(-50%, -50%);
  padding: 10px 20px;
  background-color: #007bff;
  color: #fff;
  text-decoration: none;
  border-radius: 5px;
}

.container .button:hover {
  background-color: #0056b3;
}
