  <label for="toggle"></label>
</div>

.toggle-button {
  position: relative;
  width: 60px;
  height: 30px;
}

.toggle-button input[type="checkbox"] {
  display: none;
}

.toggle-button label {
  position: absolute;
  top: 0;
  left: 0;
  width: 100%;
  height: 100%;
  background-color: #ccc;
  border-radius: 15px;
  cursor: pointer;
  transition: background-color 0.3s ease;
}

.toggle-button input[type="checkbox"]:checked + label {
  background-color: #2196F3;
}

.toggle-button label::before {
  content: "";
  position: absolute;
  top: 2px;
  left: 2px;
  width: 26px;
  height: 26px;
  background-color: #fff;
  border-radius: 50%;
  transition: transform 0.3s ease;
}

.toggle-button input[type="checkbox"]:checked + label::before {
  transform: translateX(30px);
}

document.getElementById("toggle").addEventListener("change", function() {
  // 切换按钮状态时的操作
});
