html - 无法显示 codepen 图标

问题描述

我正在尝试使用字体很棒的图标，但我看不到 codepen 图标。所有其他图标都可以正常工作。有什么方法可以让新的 Instagram 图标颜色与此颜色合并？我尝试使用 font awesome 提供的其他图标，它似乎工作。我也尝试用其他图标更改 codepen 图标的位置，但它似乎没有用。另一件事，动画似乎在图标所在的地方工作，但它没有显示任何东西。

解决方案

首先，您需要将 Font AwesomeCSS导入您的示例。

<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/font-awesome/4.7.0/css/font-awesome.min.css">

由于以下错误，我在显示 Facebook 图标时遇到问题<i> class：

<a href="#" class="icon-button facebook">
  <i class="icon-facebook"></i><span></span>
</a>
<a href="#" class="icon-button instagram">
  <i class="fa fa-instagram"></i><span></span>
</a>

我将 Facebook 更改HTML为以下内容并CSS相应地调整以使图标正常工作。

<a href="#" class="icon-button facebook">
  <i class="fa fa-facebook"></i><span></span>
</a>
