This HTML, CSS, and JavaScript code snippet provides a simple chat box interface for a website. It defines constants and functions to handle the conversation and uses the DOM API to select and manipulate HTML elements. The code allows the chatbot to respond with random messages from an array and appends messages to the chat window with avatars and time stamps. It also includes utility functions to select elements and format dates. You can easily integrate this code into their web pages to create a basic chatbot interface.

Now, load the Font Awesome JS (for icons) by adding the following CDN link before closing the body tag:
<script src='https://use.fontawesome.com/releases/v5.0.13/js/all.js'></script>
Finally, add the following JavaScript function to activate the functionality of the chatbot.
const msgerForm = get(".msger-inputarea");
const msgerInput = get(".msger-input");
const msgerChat = get(".msger-chat");
const BOT_MSGS = [
"Hi, how are you?",
"Ohh... I can't understand what you trying to say. Sorry!",
"I like to play games... But I don't know how to play!",
"Sorry if my answers are not relevant. :))",
"I feel sleepy! :("];

const BOT_NAME = "BOT";
const PERSON_NAME = "Sajad";

const msgText = msgerInput.value;
if (!msgText) return;

});
