在垂直导航栏引导程序的底部添加固定导航项-Java 学习之路

我通过在 <li> 标签中附加 style="bottom: o; position: fixed;" 来实现我目前可以实现的屏幕，如下所示：

<li style="bottom: 0; position: fixed; overlay: none;">
  <a href="#"><i class="fa fa-fw fa-paper-plane-o"></i> Bottom Item</a>
</li>

但是，正如预期的那样，当用户的屏幕较小并且导航项目靠得更近时，它们会重叠 .

Normal viewing image

Smaller screen/zoomed in viewing

因此，如果屏幕较小，那么该项目将位于导航项目的底部，但如果它很大，那么它将被卡在底部 .

谢谢 .

您应该从li中删除内联样式并将此CSS添加到项目中：

@media(min-width:992px) {
  .side-nav>li:last-child {
    position: absolute;
    bottom: 0;
  }
}

li 将保持在 md 和 lg 屏幕的底部，并将与 sm 屏幕上的其余部分分组 . 如果您希望它也在 md 上分组，请在上面的代码中将 992px 更改为 1200px .

演示：

@media(min-width:992px) {
  .side-nav>li:last-child {
    position: absolute;
    bottom: 0;
  }
}
@media(min-width:768px) {
  #page-wrapper {
    min-height: calc(100vh - 50px);
  }
}
