我正在使用下拉菜单创建固定的导航栏。不幸的是,固定栏后,下拉菜单不可见。我希望页面在必要时滚动,但导航栏必须始终可见。
我已经看到了几篇关于此的文章,但是给定的解决方案都不适合我。
下面的代码可以正常工作,但是当删除/*position: fixed;*/
周围的注释标记时,会出现问题。
问候

最佳答案
这是因为您有溢出的隐藏overflow: hidden;
从固定的选择器中将其删除。
ul {
list-style-type: none;
font-family: Arial, Times, serif;
margin: 10;
padding: 0;
background-color: #555555;
text-decoration: none;
/* remove comment below to see effect*/
position: fixed;
top: 0;
width: 100%; /* Full width */
}
