我正在尝试编辑wordpress主题。 这是网站：http://findbeauty.be
我遇到了一个问题，我无法在代码中找到需要编辑的部分。在导航栏中，您可以看到从白色导航栏中剪切部分的“白色三角形”。
我在CSS中无处不在，我找不到它。除了CSS之外还有什么方法可以获得这样的最终结果吗？在PHP还是这样？我在哪里看？
如果我使用Firebug找到元素，我会得到这个：
<nav class="nav" role="navigation">
下面添加了完整的样式表。谢谢！

答案 0 :(得分：1)
您可以在“stylesheet.css”第279行找到它：
.nav:before {
border-left-color: #fff;
border-right-width: 1.5em;
left: 0;
}
答案 1 :(得分：1)
这是css doc
中的第270行.nav:before, .nav:after {
border: 1.7em solid #000000;
bottom: 0;
content: "";
display: block;
position: absolute;
top: 0;
z-index: 1;
}
这就是你要找的东西:)它是创造这种效果的边界。希望这有帮助！
