Question

我正在尝试建立一个本地Laravel网站，以了解Laravel 5.6的新功能和差异。但是，当尝试在Bootstrap 4的navbar-brand中放置“真棒字体”图标时，似乎无法加载。当我在Chrome的检查器中检出元素时，元素尺寸为0x0。我尝试添加90px的宽度和高度只是为了查看图标，但它仍然不会显示。有什么想法吗？

Answer 1

fa-laptop-code在您正在加载的font-awesome版本中不可用。

您正在加载4.7，但如果要使用该图标，则需要加载FontAwesome 5

改为使用以下CDN：https://use.fontawesome.com/releases/v5.2.0/css/all.css

Answer 2

尝试一下，它将起作用

<i class="fa fa-laptop"></i>
