嘿，你可以這樣試試

<button class="sticky top-0" on:click={scrollUp}>Scroll Up</button>

<!-- Your divs here -->

<button class="sticky bottom-0" on:click={scrollDown}>Scroll Down</button>

嘗試運行以下JS

<script>
  let scrollIndex = 0; // Initial scroll index

  function scrollUp() {
    if (scrollIndex > 0) {
      scrollIndex--;
      scrollToDiv();
    }
  }

  function scrollDown() {
    if (scrollIndex < 4) { // Adjust the value based on the number of divs
      scrollIndex++;
      scrollToDiv();
    }
  }

  function scrollToDiv() {
    const div = document.getElementById(`div${scrollIndex}`);
    div.scrollIntoView({ behavior: 'smooth' });
  }
</script>

我相信它會對你有所幫助
