CSS-Only Chat
A truly monstrous async web chat using no JS whatsoever
css-only-chat is a proof-of-concept demonstration that implements a functioning chat interface using only HTML and CSS, without any JavaScript or backend logic. The project showcases creative use of CSS selectors, checkboxes, labels, and the :checked pseudo-class to mimic interactive behaviors normally handled by JavaScript. Messages are pre-written in the HTML and displayed based on user interaction, making it more of a playful experiment than a real messaging platform. Its main purpose is to illustrate the limits of CSS as a programming and UI tool, serving as both an educational example and a bit of humor within the developer community. By pushing CSS beyond its conventional role, it demonstrates how user interfaces can be simulated through styling tricks and static structures. Although not suitable for production use, it stands as a fun exercise in front-end creativity and unconventional coding challenges. -
