jquery - 水平溢出不起作用

Question

基本上我在容器中有一个列来显示时间，就像电视指南一样，通过添加每个小时，即 13:00 到 14:00，时间进入下一行，而不是让我水平滚动，它很难解释它基本上显示从早上 5 点到下午 1 点的 5 个小时，然后转到下一行而不是继续并允许我水平滚动我必须像我复制和粘贴一样在时间上拖动鼠标才能看到下面的时代。下面是目前的 CSS，我已经尝试了每个溢出选项，但没有任何效果。这就是我要显示的内容

 <div id = "times">
        <div class = "header">05:00-06:00</div>
        <div class = "header">06:00-07:00</div>
        <div class = "header">07:00-08:00</div>
        <div class = "header">08:00-09:00</div>
        <div class = "header">09:00-10:00</div>
        <div class = "header">11:00-12:00</div>
        <div class = "header">12:00-13:00</div>
        <div class = "header">13:00-14:00</div>
        <div class = "header">14:00-15:00</div>
        <div class = "header">15:00-16:00</div>
        <div class = "header">16:00-17:00</div>
        <div class = "header">17:00-18:00</div>
        <div class = "header">18:00-19:00</div>
        <div class = "header">19:00-20:00</div>
        <div class = "header">20:00-21:00</div>
        <div class = "header">21:00-22:00</div>
        <div class = "header">22:00-23:00</div>
        <div class = "header">23:00-24:00</div>

这是CSS

#times{
    width: 100%;
    height: 50px;
    overflow:scroll;

Answer 1

我接受了这个问题并开始思考。下面的代码片段应该会生成带有放映时间的电视指南。它仍然需要大量清理，但它做了它需要做的事情。

当我有更多时间并进一步清理它时，我会回到这里。

我让它尽可能动态。您所要做的就是提供一个位置来粘贴表格并为其提供数据，因为网格将根据提供的数据构建。
