页面底部的滚动条

Question

我不确定为什么我会在页面底部获得滚动条

正如你在上面的剪切图片中看到的，有滚动条，这意味着有一些潜水的额外宽度，但我删除了所有的CSS，但仍然给我相同的结果。谁能告诉我为什么会显示这个滚动条？

Working fiddle

Answer 1

.row {
    width: 100%;
}

Answer 2

这只是您当前的结构：您的rows和/或columns通常应遵循此模式。

容器（或容器 - 流体）/行/列 由于您有一些不在容器内的行，因此.row{margin-right:-15px;margin-left:-15px}会显示溢出。

请参阅工作示例摘录。

@media (max-width: 767px) {
  .navbar-nav > li.login {
    display: inline-block;
  }
}
