我希望我的网站在点击网页中的向右箭头时横向滚动。我制作了一个未完成的小脚本，但它没有按预期工作。 在脚本中，速率应每 10 毫秒降低一次，从而导致网页向侧面滚动。稍后我将添加一个功能，以在达到所需的边距时停止滚动。 这是代码:
<!DOCTYPE HTML>

div.length {

margin-top:-300px;

<script type="text/javascript">

最佳答案
它看起来不滚动的原因是因为页面上的所有其他 DIV 都有 position:fixed; 包含的 DIV length 可能会移动，但是箭头和灰色背景不会通过更改 length 元素的填充而移动。
要验证这一点，请向 length DIV 添加一个“watch”并在控制台中检查它。
