FlexSlider 箭头工作但不可见

Question

我尝试听从其他聊天室关于此问题的建议，但没有成功。我正在使用 Unbounce 并将所有代码从一个旧的着陆页复制到一个新的着陆页。一切正常，除了箭头不可见（但它们是可点击的，它们有效）。

到目前为止，我所做的只是移除箭头周围的框。

知道哪里出了问题吗？

Answer 1

您丢失了 Font Awesome css，这是导航箭头所必需的。

添加

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/font-awesome/4.5.0/css/font-awesome.min.css">

到 <head> 部分。（就像工作页面一样，检查它的源代码行 2825）。祝你好运。
