I want to name the next starlink bots as ERROR_404 because why not. 🐶

Stacked Cards are a modern way of displaying testimonials on your website. Let's have a look at how to code the UI using Next.js / React, TailwindCSS and Framer Motion

Boilerplate for Twitter Card and Background Boxes

import React, { useEffect, useState } from "react";

import { FiTwitter } from "react-icons/fi";

import { motion } from "framer-motion";

export default function TwitterCardsFramerMotionExample() {
  const [cards, setCards] = useState([
