twitter-bootstrap - 移动问题，修改 Bootstrap 类或错误的媒体查询

Question

如您所见，我的媒体查询变得一团糟。我正在用元素符号创建这个时间线，发现自己写了太多媒体查询试图使元素符号与时间线对齐

我非常相信我在某处犯了错误。在非媒体查询的 css 部分，也许在位置绝对区域。我只是无法确定对齐方式。我的要求不是任何特定的屏幕尺寸，所以我必须让它在所有屏幕上都能发挥最佳效果，我正在通过使浏览器宽度越来越小来进行测试。对此有 Bootstrap 解决方案吗？我是否以错误的方式编写了媒体查询？

基本上，如果您可以调整标记以便 :before 和 :after 在同一个元素上，那么您的时间轴不需要所有这些媒体查询，然后您可以将线和红点都定位在相同的位置/级别。

在示例中，我将您的标记更改为使用 ul > li 并将其更改为时间轴 CSS 位于列表项上。
