大佬教程收集整理的这篇文章主要介绍了html – Bootstrap – 浮动操作按钮菜单大小和阴影，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。

我正在使用Bootstrap 3.3和 Bootstrap Material Design framework构建一个应用程序.我正在尝试创建一个浮动操作按钮,当您单击它时会打开.

为了做到这一点,我创建了这个Bootply,其代码如下：

<div class="btn-group dropup floaTing-action-button">
    <button type="button" class="btn btn-info btn-fab btn-raised dropdown-toggle" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false"><i class="material-icons">save</i></button>
    <ul class="dropdown-menu dropdown-menu-right" style="min-width:0; BACkground-color:transparent;">
        <li><a href="#" class="btn btn-danger btn-fab btn-raised"><i class="material-icons">clear</i></a></li>
    </ul>
</div>

按钮有效,但看起来不正确.有两个问题让我疯狂.首先,弹出菜单不透明.有一种我似乎无法摆脱的边界和阴影.

其次,我无法使用Bootstrap Material Design framework页面的浮动操作按钮部分中显示的小版本按钮.我不确定我做错了什么.

解决方法

因此,bootstrap CSS中的.dropdown-menu默认为box-shadow和border,你必须重置它以使其透明.

另外在你的Bootply中它没有应用Material Design Icons,因为你没有链接字体.

关于小图标,将.btn-group-sm添加到.btn-group

这是一个工作的SNIPPET,包含各种尺寸的示例.

.floaTing-action-button {
  position: relative;
  top: 100px;
  margin-left: 50px;
}
ul.dropdown-menu {
  box-shadow: none;
  border: 0;
  min-width:0;
  BACkground:transparent
}
