.pagination-container {
  position: relative;
  width: 300px;
  height: 200px;
  overflow: hidden;
}

.page {
  position: absolute;

  width: 100%;
  height: 100%;
  opacity: 0;
  visibility: hidden;
}

.page.active {

@keyframes slideIn {
  from {
    transform: translateX(100%);
    opacity: 0;

.page.slide-in {

.page.slide-out {
  animation: slideOut 0.5s ease-in-out;

function goToPage(pageNum) {
  const pages = document.querySelectorAll('.page');
  const currentPage = document.querySelector('.page.active');
  const nextPage = document.querySelector(`[data-page="${pageNum}"]`);

  if (!nextPage || currentPage === nextPage) return;

  // 添加动画类
  currentPage.classList.add('slide-out');
  nextPage.classList.add('slide-in', 'active');

  // 动画结束后清理类
  setTimeout(() => {
    currentPage.classList.remove('active', 'slide-out');
    nextPage.classList.remove('slide-in');
  }, 500);
