添加“ Font-Awesome”后，光滑的轮播箭头被切断

Question

我正在为我的网站Peruvian Connection制作轮播。我需要设置箭头的样式。因此，我查看了stackoverflow论坛，发现可以使用Font-Awesome及其Unicode来更改箭头的形状和味道（这里的线程：如何设置上一个/下一个箭头按钮的样式？）。更改图标时，它们可以在chrome中完美运行。虽然它们在IE中已被切断，但在其他浏览器中却存在一些错误。

您可以在此处找到演示：http ://www.peruvianconnection.com/category/ads/lookbook.do?test= test

经过测试的浏览器：

Chrome-完美运行
Safari-有点点
Firefox-仅适用于特定区域。
IE 9,10,11-箭头被切除。

这是代码或Slick-Theme.css

Answer 1

在您的slick-theme.css中删除行号33和34。即

width: 20px;
height: 20px;

在IE.11中进行了测试，我希望它也适用于其他浏览器。
