前端入门求助：如何将网页导航栏（Nav bar）设置为右对齐？

问题根源 #

你写的.navbar CSS类没有对应到HTML里的<nav>元素，而且默认的列表样式、body的文本对齐设置也干扰了导航栏的布局。

修改步骤 #

1. 给HTML里的<nav>加上navbar类，让CSS样式生效
2. 重置<ul>的默认样式（去掉内边距、列表符号）
3. 用Flex布局实现导航项右对齐，同时调整页面避免内容被导航栏遮挡

body {
  background-color: #b8d8b8;
  font-family: Arial, sans-serif;
  text-align: center;
  padding-top: 60px; /* 避免内容被顶部固定导航栏遮挡 */
  margin: 0;

.header {
  background-color: #4d7d4d;
  color: white;
  padding: 10px;
  position: fixed;
  right: 0;
  top: 0;
  width: 100%;

  font-weight: bold;
}

.content {
  background-color: white;
  color: black;
  display: inline-block;
  padding: 20px;
  margin: 20px;
  box-shadow: 0 4px 8px 0 rgba(0, 0, 0, 0.2);

  border-bottom: 2px solid green;
  display: flex; /* 用Flex布局实现右对齐 */
  justify-content: flex-end;
  box-sizing: border-box; /* 避免padding撑宽导航栏 */
}

/* 重置ul默认样式 */
.navbar ul {
  list-style: none;
  padding: 0;
  margin: 0;
  display: flex; /* 让列表项横向排列 */
  gap: 15px; /* 给导航项之间加间距 */
}

.navbar a {
  color: green;
  text-decoration: none;
}

footer {
  background-color: #4d7d4d;
  color: white;
  text-align: center;
  padding: 10px;
  position: absolute;
  bottom: 0;
  width: 100%;
}

额外说明 #

• Flex布局是当前实现导航栏对齐最简洁的方案，justify-content: flex-end直接让导航内容靠右
• 给body添加padding-top，解决了固定导航栏遮挡页面内容的问题
• 重置<ul>的默认样式，去掉了列表符号和默认内边距，让布局更整洁
