Interactive Web Design with JavaScript
Transform static web layouts into tactile, high-performance interfaces. Learn how to drive visual states cleanly, handle complex user gestures, and build accessible, responsive components without framework bloat.
Like Duolingo, but for Interactive Web Design with JavaScript. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
A short one: 11 levels across 2 sections, about 22 minutes end to end, roughly 4 days at five minutes a day. It moves through Wiring Dynamic Interfaces and Refining Motion and Component Behavior. It assumes you already know the basics.

Key ideas in Interactive Web Design with JavaScript
- Inline styles override stylesheet rules and lock design decisions inside script files.
- Updating dataset attributes lets JavaScript declare high-level intent without knowing visual rules.
- CSS attribute selectors like [data-state='open'] isolate styling changes entirely to stylesheets.
- ARIA state attributes like aria-expanded update screen readers on interface changes in real time.
- CSS can query standard ARIA attributes directly using attribute selectors like [aria-expanded='true'].
- Mirroring aria-expanded with an extra .is-open class adds redundant code that can fall out of sync.
- JavaScript can set CSS custom properties at runtime via style.setProperty('--name', value).
- Passing raw numerical coordinates to CSS variables lets the browser handle smooth GPU transitions.
- Custom property updates avoid hardcoding visual layout calculations into JavaScript logic.
- Combining multiple class toggles often creates combinatorial selector clashes in CSS.
- Dataset key-value pairs enforce independent state dimensions that can change without side effects.
- Targeting compound attributes like [data-theme][data-variant] keeps variant styles predictable.
- Delegating to a single parent avoids attaching dozens of duplicate listeners to dynamic UI elements.
- Events naturally bubble up from child elements to their parent containers in the DOM hierarchy.
- A parent listener handles clicks on dynamically injected cards without needing any re-binding.
- Clicks on an SVG or child span report that nested element as event.target instead of the button.
You've tried the other tabs
Thirty open tabs. Four facts you actually kept.
You watched. You nodded. By Sunday it was gone.
One answer, then back to scrolling.
Eight weeks. You meant to finish. You didn't.
Tomo gives Interactive Web Design with JavaScript the Duolingo treatment: levels, streaks, and quick quizzes that test what you just learned. That game loop is what the tabs above never had, so it's the one you actually finish.
