72-Hour Battle Against Bloat
The Ultimate Constraint Challenge
|
In an era of bloated frameworks and 10 MB JavaScript bundles, we’ve forgotten the raw power of vanilla web technologies — what if the web could be lightning-fast again? If constraints bred innovation instead of limitation?
The Thinking Of...
|
▓ Pure HTML, CSS, and JavaScript — No frameworks, no libraries, no shortcuts

▓ Performance-first mindset — Every byte matters, every millisecond counts

▓ Technical excellence — Prove that vanilla web can outperform any framework
What can we build?
What can we build under extreme 🚨 constraints?
Build something extraordinary using only the fundamental web techs →
The Principal Challenge
Build with less. Create the impossible
적게 만들어 더 크게. 불가능을 창조하라
Choose 3 tracks from our 15 extreme constraint challenges and build one unified project that satisfies all three simultaneously. Each track represents a different technical frontier — from 1KB total file size to interfaces that work perfectly for your grandmother
The Real Challenge: Creating a single application that masters multiple constraints at once. Imagine building a CSS Alchemist + Byte Assassin + Grandma’s Digital Sage project — visual magic in under 1KB that your grandmother loves using!
Your Remit
Hack Over 15 — Choose 3
Track 1: The Byte Assassin
Build something genuinely useful in exactly 1KB of code total (HTML + CSS + JS combined). Every byte is a weapon.

Testing: Use wc -c or file size checker, must be ≤ 1024 bytes
Track 2: 2G Connection Ninja
Create a full experience that works perfectly on a 2G connection. Master the art of speed in the slowest conditions.

Testing: Chrome DevTools > Network > Slow 2G throttling
Track 3: Ancient Hardware Whisperer
Make something that loads instantly on a 2015 laptop with 4GB RAM and integrated graphics. Awaken the sleeping giants.

Testing: Chrome DevTools > Performance > CPU throttling 6x slowdown
Track 4: Grandma's Digital Sage
Build something so intuitive that your grandmother becomes a power user without any explanation. Wisdom through simplicity.

Testing: Give to someone 65+ or simulate with vision/motor impairments
Track 5: No-Script Sorcerer
Create the most complex, interactive experience possible using only HTML and CSS. Pure magic, no scripts.

Testing: Disable JavaScript entirely and verify full functionality
Track 6: Single-Request Samurai
Everything must work from a single HTTP request. Honor the ancient way of one perfect strike.

Testing: Monitor network tab — only one request allowed
Track 7: Offline Survivalist
Build something that works perfectly with zero internet connection after the initial load. Thrive in the digital wilderness.

Testing: Load page, then disconnect WiFi/disable network
Track 8: CSS Alchemist
Create something that looks impossible to build with just CSS. Transform base elements into gold.
Testing: Remove all JavaScript and verify visual magic still works
Track 9: Lightning Bolt Engineer
Build any complex application, but it must achieve a complete page load in under 1 second on mobile 3G. Harness the storm.

Testing: Chrome DevTools > Network > Fast 3G + mobile device simulation
Track 10: Universal Access Guardian
Create the most accessible web experience possible while maintaining visual appeal and functionality for all souls.

Testing: Use screen reader (NVDA/JAWS) + keyboard-only navigation + color blindness simulator
Track 11: Keyboard Sensei
Build something where 100% of functionality flows through keyboard shortcuts. The mouse is for amateurs.

Testing: Unplug your mouse and use only keyboard navigation
Track 12: Memory Monk
Create a complex application that uses less than 10MB of RAM total. Achieve enlightenment through minimalism.

Testing: Chrome DevTools > Memory tab + Performance monitor
Track 13: Legacy Browser Archaeologist
Build something that works perfectly in Internet Explorer 11. Resurrect the ancient ones with modern grace.

Testing: Use IE11 developer tools or Edge IE mode
Track 14: Text-Only Storyteller
Create the most engaging experience possible using only plain text and basic HTML formatting. Paint with words alone.

Testing: Strip all CSS and images — functionality must remain intact
Track 15: Monolith Master
Build a complete application in a single HTML file. All power contained within one sacred scroll.

Testing: Check that only one .html file exists and works standalone
