开发的Bluehedge Realtors落地页在多数移动设备上响应正常，但在三星Note21和iPhone14设备上显示异常（对应截图：三星设备截图、iPhone设备截图）。使用Chrome/Edge开发者工具等响应式测试工具无法复现该异常。

问题排查与修复方案 #

核心问题点 #

1. Viewport元标签错误：原代码中<meta http-equiv="-UA-Compatible"缺少X-前缀，应为X-UA-Compatible，可能导致部分浏览器渲染模式异常；同时未添加viewport-fit=cover，无法适配iPhone14等刘海屏设备。
2. 固定定位元素适配问题：.address仅设置width:100%和bottom:0，未指定left:0和right:0，在部分设备上可能出现宽度未铺满的情况。
3. 页面高度适配问题：main未设置min-height:100vh，导致在部分设备上内容无法垂直居中；body设置overflow:hidden会截断超出视口的内容，移动端应改为overflow-x:hidden保留纵向滚动。
4. 背景图适配问题：未设置background-position:center，部分设备可能出现背景图偏移。
5. 按钮宽度硬编码：移动端按钮使用固定宽度300px，无法适配不同宽度的小众设备，建议改用百分比宽度。
