Question

滚动时有人可以帮我让div消失吗？

例如，如果我有一个简单的标题和下面的一堆段落，我滚动，我希望标题保持固定在顶部，它下面的段落滚动过去并消失在标题下方。到目前为止，我尝试了以下内容：

基本上，我将标题的样式设置为position: fixed，但段落不会消失。有人可以帮忙吗？

提前致谢！

Answer 1

这会整理一下......

.container1 {
  position: fixed;
  top: 0;
  width: 100vw;
  background-color: #FFFFFF;
  z-index: 1;
}

.container2 {
  position: relative;
  margin-top: 80px;
}

Answer 2

我不确切地知道你想要做什么，但也许这可以回答你的问题：

.container1 {
  position: fixed;
  z-index: 1;
  background: #fff;

}
