Built a Modern Rice Purity Test Website. Here's My Tech Stack and the Challenges I Faced.

You've probably heard of the Rice Purity Test — it's a self-graded survey that originated at Rice University to gauge a person's level of "innocence" or life experience. I noticed that many existing versions online were full of intrusive ads and had clunky user experiences from the early 2000s.

So, I decided to build a modern, clean, and ad-free version: Rice Purity Test.

I wanted to share my process, the tech stack I used, and a few interesting challenges I ran into. I hope this can be useful, especially for newer developers thinking about their own projects.

🛠️ The Tech Stack

Frontend: Vanilla HTML, CSS, and JavaScript. For a simple, mostly static site like this, a framework felt like overkill. I wanted it to be incredibly lightweight and fast.
Styling: Custom CSS with a mobile-first approach. I used CSS Grid and Flexbox for the layout to make it fully responsive on all devices.
Hosting: GitHub Pages. It's free, simple, and perfect for static sites. The connection is served over HTTPS, which is a must-have.
Domain: Namecheap for the d domain (ricepurity.info).

⚡ Challenges & Solutions

Persisting the Score State: The test has 100 questions. I needed a way to save the user's answers so that if they refreshed the page or left and came back, their progress wouldn't be lost.

Solution: I used the localStorage API. Every time a checkbox is checked or unchecked, the state of all answers is saved to localStorage. On page load, the script checks for saved data and re-populates the test.

Calculating the Score Dynamically: The score (a number from 0-100) needed to update in real-time without refreshing the page.

Solution: This was a fun JavaScript logic problem. I attached an event listener to the entire form. Any time a click event happens, the function calculates the score by counting all the checked checkboxes (each "yes" subtracts a point from 100) and updates the displayed score instantly.

// Simplified version of the calculateScore function function calculateScore() { const checkboxes = document.querySelectorAll('input[type=checkbox]'); let score = 100; checkboxes.forEach(checkbox => { if (checkbox.checked) { score--; } }); document.getElementById('score-value').textContent = score; }

Creating a Shareable Result: I wanted users to be able to share their final score easily.

Solution: I implemented a simple "Share Your Score" button that copies a pre-formatted message (e.g., "I scored a 92/100 on the Rice Purity Test! 🎯 ricepurity.info") to the user's clipboard using the navigator.clipboard.writeText() API.

🚀 What's Next?

This was a super fun weekend project. Future ideas might include:
Creating data visualizations of anonymous aggregate score data.
Adding a "dark mode" toggle (because what modern app doesn't have one?).
Allowing users to create custom test lists.

I'd love to hear your feedback! Have you taken the test? What would you have done differently in the tech stack? Let me know in the comments!
