强调不正确的宽度

Question

导航链接有一个动画下划线，屏幕尺寸＆lt; 555px显示为100％页面宽度时，它们应该只显示文本的宽度。将显示更改为内联块会更改宽度，但我希望链接显示在彼此之上而不是并排显示？

Answer 1

您可以将动画移动到a标签，然后使用.navlist项将每个项目分隔到各自的行中：

从链接中获取样式属性，并在CSS中定义该属性，而不使用width定义。

.navlist a {
  display: inline-block;
}

将动画从.navlist移开并将其放在a内：

.navlist a:after {
  content: '';
  display: block;
  height: 1.5px;
  width: 0;
  background: transparent;
  transition: width .5s ease, background-color .5s ease;
}
.navlist a:hover:after {
  width: 100%;
  background: grey;
  transition: width .5s ease, background-color .5s ease;
}

使.navlist项阻止，以便每个链接显示在各自的行上：

.navlist {
  display: block;
}

Answer 2

将width添加到ul并将其居中，然后从display: block移除li： http://jsfiddle.net/2tycjc82/7/
