Step 1: Create the HTML Form

The first step is creating an HTML form allowing users to send chat messages. We’ll have a text input field for the message and a submit button.

<span style="font-weight: 400;"><form id="chat-form"></span>

<span style="font-weight: 400;">  <input type="text" id="chat-input"></span>

<span style="font-weight: 400;">  <button type="submit">Send</button></span>

<span style="font-weight: 400;"></form></span>

We’ve given the form and input an ID to access them from our JavaScript.

Step 2: Create the Chat Box Container

Next, we’ll add an HTML element to contain our chat box messages. Here we use a <div> with an ID of “chat-box.”

<span style="font-weight: 400;"><div id="chat-box"></div></span>

This element will populate with new chat messages as users submit them. Now, let’s take a look at adding some basic chat box design html css.

Step 3: Add Basic CSS Styling

Now let’s add some basic chat box design HTML CSS code to position and style our html chat box. We’ll center the form, set a width on the chat box container, and style the chat messages.


#chat-form {

text-align: center;


#chat-box {

width: 300px;

margin: 20px auto;


.chat-message {

padding: 10px;

margin: 10px 0;

background: light gray;


And that’s all for the chat box CSS, but feel free to edit it as needed.

Step 4: Add JavaScript to Send/Receive Chat Messages

We’ll add JavaScript to listen for form submissions, send the message data to our chat box, and reset the input field.

const form = document.getElementById("chat-form");

form.addEventListener("submit", e => {


const input = document.getElementById("chat-input");

const message = input.value;


input.value = "";


function addMessage(message) {

const div = document.createElement("div");


div.innerHTML = message;



This basic JavaScript will allow us to send messages from our HTML chat box!

Step 5: Add Styling to Individual Chat Messages

Let’s improve our chat message styling with some CSS:


float: left;

clear: both;



float: right! Important;

background: green;

color: white;


We can now target a “current-user” message to float it to the right.

And that’s it; we created an html chat box widget from scratch using only HTML, CSS, and JavaScript. We used plain CSS for our chat box design, which turned out well.

These instructions offer an excellent foundation to design your unique chat box without utilizing a third-party embed code. But there are undoubtedly many ways we could enhance and tweak this straightforward chat box.
