我正在创建一个带有bootstrap和jquery的登录屏幕,其中必须集中访问卡。
问题是,当垂直滚动条出现时,滚动到顶部并不能显示所有内容,facebook的按钮也无法访问(取决于高度,谷歌的也是)。
为了补偿导航栏的高度,我在主体和父div上测试了padding-top,但没有成功。
我还试着在卡片前添加一个带有clearfix的br,但没有效果。

现在,我添加了一个新的类来防止卡片扩展到很多,设置了max-height,HTMl中的类和新的CSS用注释标记。 我将尝试进一步调查这一点,并找出确切的原因,这发生了,但你可以尝试这一点,看看它是否修复了您的网页上的问题。 在片断中是这样的。
