HTML/CSS

In this article, I will be providing a simple Mobile Responsive Chatbox UI Template. The Chatbox UI Template is written in HTML, CSS, and JavaScript. The primary purpose of this article is to share a free Chatbox UI Template for students or beginners for their website chat feature or chatbot feature of their projects.

How does this Mobile Responsive Chatbox UI Template work?

This Mobile Responsive Chatbox UI Template contains the relevant component or HTML element that is often implemented in a chatbox for a website. It is a pop-up block or panel that has a conversation box between the sender and receiver. The chatbox is divided into 3 panels which are the Chatbox Header, Body, and Footer. The chatbox's header is the area of the said UI where the chatbox title (username/Chatbot name) and the close button are located. The chatbox's body area contains the conversation of the users. The footer contains the chat form which has a text field and a send button. The chatbox can be triggered to show by clicking the chat icon that is located at the bottom-right corner of the web page.

Features

  • Chatbox Icon Button w/ Animation Effect - (trigger the Chatbox to show)
  • Chatbox Header/Title Bar
  • Chatbox Conversation Area
    Contains:
    • User Avatar
    • Message Bubble
    • Message Content
  • Auto-resizing chat Textfield
  • Send Button

Requirements

This Chatbox UI Template is using Google Icons which means that you are required to load the Google Icons Asset for implementing the template into your own project.

I have provided also the complete source code zip file of a sample web page that uses the scripts I provided above to demonstrate the Responsive Chatbox UI template in an actual web page. The download button is located below this article's content. Feel free to download and modify it.

That's it! I hope this Mobile Responsive Chatbox UI Template Source Code in HTML, CSS, and JS will be useful for what you are looking for and will be useful for your current and future web application projects.

Explore more on this website for more Tutorials and Free Source Codes.

Happy Coding =)

Note: Due to the size or complexity of this submission, the author has submitted it as a .zip file to shorten your download time. After downloading it, you will need a program like Winzip to decompress it.

Virus note: All files are scanned once-a-day by SourceCodester.com for viruses, but new viruses come out every day, so no prevention program can catch 100% of them.

FOR YOUR OWN SAFETY, PLEASE:

1. Re-scan downloaded files using your personal virus checker before using it.
2. NEVER, EVER run compiled files (.exe's, .ocx's, .dll's etc.)--only run source code.
