如何将div附加到可折叠的导航栏

标签: css bootstrap-4

基本上,我在页面顶部有一个导航栏。该导航栏具有折叠功能,因此菜单仍可用于小屏幕。我想在此可折叠导航栏的底部附加一个div。更具体地说,在屏幕的右侧,将有一个红色的圆圈,它以导航栏的边框为中心。

我正在寻找这样的东西: enter image description here 圆圈不是按钮。可折叠按钮仅在小屏幕上出现(在导航栏的右侧)

我尝试了许多在互联网上找到的建议。他们中的大多数建议给父div相对于子div的绝对位置。但是它从来没有奏效,而且只有这样做了,它才没有响应。

这是我当前的HTML无响应代码

.circle {
  position:absolute;
  <--top:35px;-->
  right:3vw;
  width:20px;
  height:20px;
  background: #d21c2d;
  border-radius:50%;
}
<link href="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css" rel="stylesheet"/>
<nav class="navbar navbar-fixed-top navbar-expand-lg green-background">
    <div class="container-fluid">
       <-- 80 lines of navbar code including a collapse navbar-collapse div -->
    </div>
    <div class="circle"></div>
</nav>

到目前为止,我唯一能做的就是将圆圈放置在给定尺寸的屏幕上。如果屏幕尺寸改变,则不稳定。它也不具有可折叠模式。

非常感谢您的帮助。 祝你有美好的一天:)

通过在导航栏中添加元素并添加以下属性来进行尝试:

.circle{
position:absolute;
z-index: 1001;
right: 35px;
top: 45px; 
width:20px;
height:20px;
background: #d21c2d;
border-radius:50%; 
}

您可以使用calc进行计算。您可以根据需要从总数px中减去%

.circle {
  position:absolute;
  top: calc(100% - 10px);
  right:30px;
  width:20px;
  height:20px;
  background: #d21c2d;
  border-radius:50%;
}
