作品集网站CSS故障：无法正常设置Section（如About Me）布局

作品集网站板块布局问题修复方案

核心问题诊断

body布局限制：当前body设置了display: flex; align-items: center; overflow: hidden，强制所有内容垂直居中且隐藏超出视口部分，直接导致下方的About Me、Contact等板块无法显示。
导航栏遮挡内容：固定定位的导航栏（高度100px）未预留顶部空间，页面内容会被导航栏覆盖。
HTML语法错误：第一个section标签内多了一个多余的</div>闭合标签，可能引发布局异常。

额外优化说明

给导航栏菜单项添加锚点链接，点击可直接跳转对应板块
补充原代码缺失的动画关键帧定义
给板块标题和文本添加样式，增强视觉层次感
设置section最大宽度并居中，避免大屏下内容过度拉伸
