我有一个滑动下划线网址效果（如下所示：http://codepen.io/Dingerzat/pen/XNgKmR），当我将其与调整大小标头结合使用时，后者会导致前者不起作用。删除各个部分后，我发现罪魁祸首是＆＃34;标题导航中的行高＃34;调整大小头CSS中的类，但我需要在代码中调整大小调整页眉链接以便在滚动时进行调整。
有没有办法让这两段代码一起玩？

答案 0 :(得分：2)
问题的原因是当你使用line-height时它会使所有元素都有一个垂直间距，所以这些效果在标题之外，因为你使用overflow: hidden;它们无法显示。
您可以通过添加top: 90px; .sliding-u-l-r-l：和 .sliding-u-l-r-l之后
或者您可以将line-height替换为标题导航中的margin-top
