为什么Firefox，Safari和Chrome之间的滚动不一致？

Question

我正在http://helpir-staging.herokuapp.com上处理此网页。 它不是完美的，但在Safari上可以很好地滚动。 在Firefox中，它仅使用箭头键滚动（没有鼠标滚动），而在Chrome中，我根本没有滚动。

我的CSS一定有一些可怕的错误。 任何帮助将非常感激。

我正在使用引导程序，引导卡，angularjs和angular-dynamic-layout。

Answer 1

您的脚本供应商（idk是什么）正在破坏它，在chrome下，我看到了：

body, html {
    overflow-y: hidden;
    -webkit-overflow-scrolling: touch;
}

将隐藏更改为可见，并且至少在Chrome中有效。 在供应商脚本和css属性应固定之后，初始化您的自定义css文件。
