关于chrome的Bootstrap 3奇怪的词缀问题

Question

所以我试图使用bootstrap词缀功能,但它很奇怪.当您尝试向下滚动标题部分时,它会自动转到顶部.当屏幕宽度低于1100px时会发生这种情况.当您使用滚动条滚动时,它也仅在Chrome上.我有一个bootply设置来演示发生了什么.所以有人可以帮我弄清楚发生了什么事吗？

观看此视频可能会有所帮助.

我不知道这是怎么发生的，但是在使用 bootply 一段时间之后。我有一个解决办法。

我认为导致它的原因是box-sizing:border-boxat bootstrap.min.css (line 7)。

要么改变它，要么覆盖它box-sizing:content-box似乎可以解决这个问题。

如果您有自定义 CSS 文件，请使用以下类来覆盖 Bootstrap。

* {
    box-sizing:content-box;
}
