Web development looks overwhelming until you realize it's mostly the same
30 concepts showing up in different forms. The problem isn't the volume —
it's never knowing where to start, or what's safe to skip.
Codenus Holes breaks it down into cells. Each cell is one skill: HTML document
structure, CSS flexbox, JavaScript fetch API, Git basics. You read a short
lesson, answer a few questions, and the cell fills in. No 8-hour video courses,
no theory that goes nowhere. Just the parts that actually matter when you sit
down to build something real.
29 lessons across HTML, CSS, JavaScript, SEO, accessibility, deployment, design,
and web fundamentals. Each one takes 5 to 8 minutes. The content is direct —
what something does, when to use it, and what to avoid. No padding, no
motivational preamble, no filler.
After every lesson there's a quiz. Multiple choice, multi-select, context
questions — you can't tap through it without reading. Your score builds XP
that feeds a level system showing where you actually stand, not where you
hope you are.
The skill grid fills in as you go. You can see exactly what you know and what's
still missing. It's harder to overestimate yourself when the gaps are sitting
right there on a grid.
Between lessons: two mini-games. A tag shooter where you tap correct HTML and
CSS terms before they fall off screen. A code swipe game where you judge whether
a snippet is written correctly or broken. Both take under two minutes. Both
cover the same material from the lessons — just through a different angle.
A daily energy system paces sessions — five a day, refills overnight.
Gentle enough to not feel like pressure. Enough structure to build a habit.
Goals track your streak, lessons done, and XP earned. Achievements unlock
by doing actual things in the app, not by paying for them.
Dark interface. Monospaced where it counts. Built for people who want to
learn web development without the noise.
First three lessons open immediately. Each one you finish unlocks the next.
No paywalls. No premium tiers.
