侧边栏列表中的图标不可见 li class="nav-item"

Question

我需要将图标放在侧边菜单的文本之前。我试了很多方法都不管用。

<div class="collapse navbar-collapse" id="navbarCollapse">
<ul style="background-color:purple; padding-left: 20px;" class="navbar-nav mr-auto sidenav" id="navAccordion">
  <li class="nav-item">
    <a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a>
  </li>
  <li class="nav-item">
    <a class="nav-link" href="#">Property <span class="sr-only">(current)</span></a>        
  </li>
</ul>
</div>

我尝试了以下组合

<li class="nav-item">
<a href="#">
  <li><a href="#">Envelope icon: <span class="glyphicon glyphicon-envelope"></span></a></li>
</a>
</li>

<li class="nav-item">
    <p><a href="#"> <i class="fa fa-home fa-fw"> </i>&nbsp; Home </a></p>
</li>

<li class="nav-item">
    <a class="nav-link" href="#"> <i class="fa fa-home fa-fw"> </i> Home <span class="sr-only">(current)</span></a>
</li>

这是我的输出屏幕，其中没有可用图标

Answer 1

我看到您正在尝试使用 FontAwesome 图标。您是否在 <head> 中引用了适当的 fontawesome.css？

即；

<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/4.7.0/css/font-awesome.min.css">

也许这样的事情应该有所帮助？让我知道。

<div class="collapse navbar-collapse" id="navbarCollapse">
<ul style="background-color:purple; padding-left: 20px;" class="navbar-nav mr-auto sidenav" id="navAccordion">

  <li class="nav-item">
    <div class="logo">
  <img style="width:25px; height:25px" src="https://png.pngtree.com/png-clipart/20191120/original/pngtree-outline-home-icon-and-symbol-isolated-png-image_5045551.jpg">
    <a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a>
  </li>
  
  <li class="nav-item">
  <div class="logo">
    <img style="width:25px; height:25px" src="https://img.icons8.com/all/500/property.png">
                </div>
    <a class="nav-link" href="#">Property <span class="sr-only">(current)</span></a>        
  </li>
</ul>
</div>
