无法获得水平菜单栏答案

【问题标题】：Cannot get horizontal menu bar无法获得水平菜单栏
【发布时间】：2023-03-03 19:53:01
【问题描述】：

我的菜单栏无法水平显示。我仍在处理整个页面本身，但只需要关注未正确显示的#nav 项目。现在它看起来居中，我希望它在右上角内嵌。

我该如何解决这个问题？

  background-size: 30%;
  background-repeat: no-repeat;
  height: 500px;
  top: 0;
  font-family: cursive;
  margin: 0 auto;
  max-width: 500px;

标签： html css menu

【解决方案1】：

只需将display: inline-block; 添加到您的#nav li

#nav li {
    margin: 10px;
    float: left;
    background-color: pink;
    display: inline-block;
    height: 25px;
    border-radius: 5px;
}

body {
  background-image: url("http://i59.photobucket.com/albums/g304/ecarlson_2010/Mobile%20Uploads/2E3938F1-33FA-4CF1-A13A-F86E536A7CEA.jpg");
  background-size: 100% 100%;
  background-repeat: no-repeat;
  font-family: cursive;
  margin: 0 auto;

#nav ul {
  list-style-type: none;
  margin: 0;
  padding: 0;
