为什么我的导航栏是垂直的而不是水平的

Why is my nav bar vertical and not horizontal

我试过更改显示并删除一些代码?可能删除了错误的东西或某些代码重叠?我是 web 开发的新手,所以如果你能解释我做错了什么,那将非常感谢。查看此 JSFiddle link 上的代码。 https://jsfiddle.net/galbruh/htsrmy0L/2/#&togetherjs=PjjPVg1cOR

.toc-nav {
  float: left;
  /*list-style: none;*/
  margin-top: 2%;
  /*margin-left: 10%;
    margin-right: 0%;*/
width: 100%;
  text-align: center;
}

.toc-nav li {
  display: incline;
  list-style-type: none;
}

.toc-nav li a {
  color: white;
  text-decoration: none;
  padding: 10px 70px;
  font-family: "Roboto", sans-serif;
  font-size: 16px;
}

.toc-liv li.active a {
  border: 1px solid white;

  .toc-nav li a {
    float: left;
    /*display: none;*/
    width: 100%;

您在 display: incline 中有一个拼写错误,它实际上拼写为 inline。这解决了它。
