我是新来的，我需要你们的帮助很少。我一直在尝试解决这个问题，但没有找到任何办法，希望有人能帮助我。

如果您向下滚动到出现推荐的“人们在说什么”部分。
您会注意到左箭头没有出现但右箭头出现正常，即使左侧箭头框也有箭头，但仍然没有出现，有人可以帮我找到问题出在哪里以及为什么没有出现。
这是代码部分
<ul class="flex-direction-nav">
<li>
<a class="flex-prev" href="#"></a>
</li>
<li>
<a class="flex-next" href="#"></a>
</li>
</ul>
这是它的css

flex-prev 没有显示箭头，但是 flex-next class 显示的箭头很好
两者都包含可以正常工作的 css 类，不确定还有什么原因导致这里....
最佳答案
做一件事转到 flexslider 的演示。右键单击然后单击查看页面源。之后进入演示的源并找到 flexslider.css。只需将 css 代码复制到您的 flexslider.css 代码中。然后谷歌查找 bg_direction_nav.png flexslider。
你会发现两个箭头图像。将它下载到你的系统中。然后转到 flexslider.css 并在第 51 行更改:
.flex-direction-nav a {
width: 30px;
height: 30px;
margin: -20px 0 0;
display: block;
background: url(images/bg_direction_nav.png) no-repeat 0 0;
position: absolute; top: 50%; cursor: pointer;
text-indent: -9999px;
opacity: 0;
-webkit-transition: all .3s ease;
}
更改背景:url(指向新保存的图片)
然后保存一切。刷新页面，你会得到箭头。

关于javascript - 箭头不出现需要CSS代码的帮助，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/23301673/
