free work I think – chickenwings

so I copied this video https://www.youtube.com/watch?v=_sxoqRIbW0c

this is what I got from it

for the html

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8" />
  <meta name="viewport" content="width=device-width, initial-scale=1.0" />
  <title>Chat App</title>
  <link rel="stylesheet" href="style.css" />
</head>
<body>
  <div class="container">
    <div class="chat-header">
      <h3>Chat App</h3>
    </div>

    <div class="chat-body" id="chat-body"></div>

    <div class="chat-input">
      <input type="text" id="message-input" placeholder="Type a message..." />
      <button id="send-btn">Send</button>
    </div>
  </div>

  <script src="script.js"></script>
</body>
</html>

i got this for the styles.css

* {
  margin: 0;
  padding: 0;
  box-sizing: border-box;
  font-family: Arial, sans-serif;
}

body {
  background: #f5f5f5;
  display: flex;
  justify-content: center;
  align-items: center;
  height: 100vh;
}

.container {
  width: 400px;
  background: #fff;
  border-radius: 10px;
  overflow: hidden;
  box-shadow: 0 0 10px rgba(0,0,0,0.1);
}

.chat-header {
  background: #4a76fd;
  color: #fff;
  padding: 15px;
  text-align: center;
}

.chat-body {
  height: 400px;
  padding: 15px;
  overflow-y: auto;
}

.message {
  margin-bottom: 15px;
  padding: 10px;
  background: #eaeaea;
  border-radius: 5px;
  width: fit-content;
  max-width: 80%;
}

.message.you {
  background: #4a76fd;
  color: #fff;
  margin-left: auto;
}

.chat-input {
  display: flex;
  border-top: 1px solid #ddd;
}

.chat-input input {
  flex: 1;
  padding: 15px;
  border: none;
  outline: none;
}

.chat-input button {
  padding: 15px 20px;
  background: #4a76fd;
  color: #fff;
  border: none;
  cursor: pointer;
}

and this for js

const chatBody = document.getElementById("chat-body");
const messageInput = document.getElementById("message-input");
const sendBtn = document.getElementById("send-btn");

function addMessage(text, sender = "you") {
  const message = document.createElement("div");
  message.classList.add("message", sender);
  message.textContent = text;
  chatBody.appendChild(message);
  chatBody.scrollTop = chatBody.scrollHeight;
}

sendBtn.addEventListener("click", () => {
  const text = messageInput.value.trim();
  if (text !== "") {
    addMessage(text, "you");
    messageInput.value = "";
  }
});

messageInput.addEventListener("keypress", (e) => {
  if (e.key === "Enter") {
    sendBtn.click();
  }
});
