Chat UI Kit — WhatsApp-Style Chat Interface Components (HTML/CSS/JS)

Chat UI Kit — WhatsApp-Style Chat Interface Components

Build a messenger-style chat interface in minutes, not days. Chat UI Kit is a ready-to-use, zero-dependency chat UI in plain HTML, CSS and JavaScript — a chat list sidebar plus a full chat window with message bubbles, read ticks, typing indicator and dark mode. Open index.html and it just works — no build step, no framework, no server needed.

Features

• Chat list with live search filter, unread badges and online indicators
• Chat window with incoming/outgoing bubbles and blue read ticks
• Working message composer — send a message and get a simulated auto-reply with an animated typing indicator
• Emoji picker, dark mode toggle, and fully responsive mobile view (one pane at a time with back button)
• XSS-safe rendering — message text is escaped, so typed HTML shows as harmless text
• Zero dependencies — no framework, no CDN, works offline in any modern browser

What's Inside

index.html (demo page) · chat.css (all styles + theme variables) · chat.js (contacts, search, send, auto-reply) · README.txt (setup + customization guide)

Setup

Download the zip, unzip, and open index.html in any browser. Edit the CONTACTS array in chat.js for your own chats, and restyle with the CSS variables at the top of chat.css.
