Practice your HTML and CSS knowledge

by HELO Store

We have developed an in-house trivia / quizz game to help our trainees to practice and improve their CSS and HTML knowledge and skills, and to ease the pain of memorizing hundreds of tags, properties, values and definitions.
The game is now public under the name "Ophmisu Trivia" and is available for anyone to play at

Moreover, the project is open-source and available in 2 components:

- the Web client, written in PHP (Symfony2) and JavaScript (AngularJS, Socket.IO) -

- the server, written in JavaScript (Node.JS, Socket.IO, MariaDB or MySQL) -

Happy practicing!
