如何让这段TailwindCSS代码在所有断点下实现响应式？

核心问题分析 #

你的布局在移动端失效的原因集中在三点：

• 固定12列网格在小屏幕下元素过窄，aspect-square导致方块尺寸异常
• 大字号文本未做响应式调整，容易溢出容器
• 底部卡片横向布局在移动端空间不足

具体修改方案 #

1. 响应式网格列数：给所有网格容器添加断点类，根据屏幕宽度动态调整列数（小屏幕3列、平板6列、桌面保持12列）
2. 响应式文本尺寸：将固定字号替换为Tailwind响应式字号类，确保不同屏幕下文本适配
3. 卡片布局自适应：底部卡片容器添加flex-col md:flex-row，移动端纵向排列，桌面横向排列
4. 优化间距与溢出：添加全局内边距避免内容贴边，给弹性元素加换行属性防止溢出

额外优化说明 #

• 用Array.from循环生成重复网格元素，减少冗余代码
• 添加全局px-4内边距，避免小屏幕内容贴边
• 给文本添加text-center，优化移动端阅读体验
• 卡片内的弹性元素添加flex-wrap，防止标签类元素溢出
