最近在用nextjs+shadcn+tailwindcss练手，实现一个博客。做到了overView这里，可实现如下效果
1.首先要安装tailwindcss，这个在创建项目的时候就安装了。
2.然后安装shadcn,官网教程：
3.代码如下：
import {Card,CardContent
} from "@/components/ui/card"
import { cn } from "@/lib/utils";export type StatItem = {label: string;value: string | number;change?: string;changeVariant?: "up" | "down";
};type Props = {items: StatItem[];
};// TODO fetch data
const defaultItems: StatItem[] = [{ label: 'Total Views', value: '23,569', change: '+37', changeVariant: 'up' },{ label: 'Total Renenue', value: '¥ 0' },{ label: 'Follows', value: 181 },{ label: 'Stars', value: 352 },
];export default function StatsOverview({ items = defaultItems }: Props) {return (<Card className="rounded-xl border-gray-200"><CardContent className="p-6"><div className="flex flex-col sm:flex-row sm:items-stretch gap-4">{items.map((item, idx) => (<divkey={idx}className={cn("flex-1 min-w-0 px-4 py-3 bg-transparent",// add divider between items except firstidx !== 0 ? "sm:border-l sm:border-gray-200" : "")}><div className="text-sm text-gray-500">{item.label}</div><div className="mt-2 flex items-center gap-3"><div className="text-3xl font-semibold leading-tight">{item.value}</div></div><div>{item.change ? (<divclassName={cn("inline-flex items-center px-2 py-0.5 text-sm font-medium rounded text-white",item.changeVariant === "down" ? "bg-red-500" : "bg-green-500")}><svgclassName="w-2 h-2 mr-1"viewBox="0 0 15 15"fill="currentColor"xmlns="http://www.w3.org/2000/svg">{item.changeVariant === "down" ? (<path d="M5 7l5 5 5-5H5z" />) : (<path d="M5 13l5-5 5 5H5z" />)}</svg><span>{item.change}</span></div>) : (<div className="mt-2 text-xs text-gray-400">No Change Yesterday</div>)}</div></div>))}</div></CardContent></Card>);
}4.效果如图：
