Css 为网站上的部分滚动动画。

我在我的公文包网站上工作，我想知道当我向下滚动网站时，如何使文本块出现？因此，当有人向下滚动时，请说“我的关于我的示例”部分出现在左侧。

这取决于您要查找的鼠标滚动上的文本效果。这是我曾经用过的一个很好的小时间线。您可以更改此选项以表示您喜欢的内容：

HTML

JavaScript

($) {

    $(document).ready(function() {
        setupFade();
        setupClickToScroll();
        setupPostAnimation();
        setupScrollToTop();
     enableScrollAbortion();

        // Trigger window.scroll, this will initiate some of the scripts
        $(window).scroll();
  });


  // Allow user to cancel scroll animation by manually scrolling
  function enableScrollAbortion() {
    var $viewport = $('html, body');
    $viewport.on('scroll mousedown DOMMouseScroll mousewheel keyup', function(e) {
        if ( e.which > 0 || e.type === 'mousedown' || e.type === 'mousewheel') {
             $viewport.stop();
        }

这个问题可以通过谷歌搜索得到答案。这个网站不是为我们做你的研究抱歉Jessica，你必须提供一些代码来显示你正在努力完成什么，至少你是在自己的第一次尝试。我可以告诉你，它是js和css的混合体，但是这个答案和你的问题一样笼统。这是一篇针对stackoverflow新用户的有用文章：
