Question

我正在继续开发我的网站，现在又遇到了另一个问题。

当导航栏在较小的屏幕上折叠时，似乎有一个滚动条表示元素溢出。

我尝试使用overflow:hidden属性在CSS中删除此问题，但它似乎无法正常工作。

请参阅下面的屏幕截图和代码段以查看问题。

@font-face {

如何删除此滚动条？

Answer 1

事实上，这个问题似乎更容易回答。
在Bootstrap中，overflow - x文件中默认启用了bootstrap.css属性。

.navbar-collapse {
padding-right: 15px;
padding-left: 15px;
overflow-x: visible;
-webkit-overflow-scrolling: touch;
border-top: 1px solid transparent;
-webkit-box-shadow: inset 0 1px 0 rgba(255, 255, 255, .1);
box-shadow: inset 0 1px 0 rgba(255, 255, 255, .1);
}

要解决此问题，需要进行简单的属性更改。 Overflow-x:hidden

所以在折叠的导航栏上不再滚动！

Answer 2

此CSS规则导致您的溢出。

li {
  display:inline;
  margin:0 -1px;
}

删除它，只需使用特定选择器定位元素即可。现在，您的菜单将在移动设备和您的悬停属性上保持对齐，以显示蓝色。
