**To build mobile-responsive layouts that collapse asymmetric designs, enforce a `DESIGN_VARIANCE` of at least 4, define desktop columns with CSS Grid, explicitly declare single-column fallbacks at the component level, and use `min-h-[100dvh]` instead of `h-screen` according to the Leonxlnx/taste-skill source code.**

The **Leonxlnx/taste-skill** repository provides a strict design system for generating bold, asymmetric page structures that snap to a single column on mobile without horizontal scroll or layout jumping. Understanding how to build mobile-responsive layouts that collapse asymmetric designs starts with three dials—variance, motion, and density—and a set of non-negotiable rules recorded in [`skills/taste-skill/SKILL.md`](https://github.com/Leonxlnx/taste-skill/blob/main/skills/taste-skill/SKILL.md) and [`skills/stitch-skill/SKILL.md`](https://github.com/Leonxlnx/taste-skill/blob/main/skills/stitch-skill/SKILL.md).

## Asymmetric Layout Rules in the Taste Skill Framework

### Raise the Design Variance Dial to 4 or Higher

In [`skills/stitch-skill/SKILL.md`](https://github.com/Leonxlnx/taste-skill/blob/main/skills/stitch-skill/SKILL.md), the framework states that centered hero sections are banned once variance exceeds 4. When `DESIGN_VARIANCE` is set to its default of 8, the agent must choose split-screen, left-aligned, or asymmetric whitespace layouts instead of symmetric centering. This parameter is the first gate that forces an asymmetric column structure for desktop viewports.

### Declare Mobile Collapse Explicitly at the Component Level

The [`skills/stitch-skill/SKILL.md`](https://github.com/Leonxlnx/taste-skill/blob/main/skills/stitch-skill/SKILL.md) §7.2 rule demands that every multi-column layout collapses to a single column below 768 px with no exceptions. In practice, this means pairing every `grid-cols-*` definition with an explicit `grid-cols-1` fallback—or relying on Tailwind's mobile-first default—in the same component file. This keeps the responsive behavior self-documented and deterministic.

### Prefer CSS Grid Over Flexbox Math

As implemented in [`skills/taste-skill/SKILL.md`](https://github.com/Leonxlnx/taste-skill/blob/main/skills/taste-skill/SKILL.md) §3.5, the framework prohibits `calc()` percentage hacks and flexbox-based width math. CSS Grid provides deterministic column fractions that collapse automatically when the breakpoint changes, eliminating the fragile percentage calculations that break on mobile.

### Lock Viewport Height with min-h-[100dvh]

The same [`skills/taste-skill/SKILL.md`](https://github.com/Leonxlnx/taste-skill/blob/main/skills/taste-skill/SKILL.md) §3.5 section bans `h-screen` for full-height hero sections. Because iOS Safari's dynamic address bar causes vertical jump with `100vh`, the repository mandates `min-h-[100dvh]`. This guarantees the section fills the visible area without triggering a relayout when browser chrome expands or collapses.

## Production-Ready Component Examples

### Asymmetric Hero with Mobile Collapse

The following component from [`src/components/Hero.tsx`](https://github.com/Leonxlnx/taste-skill/blob/main/src/components/Hero.tsx) demonstrates a split-screen hero that is two columns on desktop and a single column on mobile, wrapped in a centered max-width container.

```tsx
/*  src/components/Hero.tsx  */
"use client";

import { motion } from "motion/react";

export function Hero() {
  return (
    <section className="grid grid-cols-1 md:grid-cols-2 gap-8 max-w-[1400px] mx-auto min-h-[100dvh] px-4 py-12">
      {/* Left side – image or illustration */}
      <motion.div
        className="flex items-center justify-center"
        whileInView={{ opacity: 1, x: 0 }}
        initial={{ opacity: 0, x: -50 }}
        transition={{ duration: 0.6, ease: "easeOut" }}
      >
        <img
          src="/hero-image.webp"
          alt="Hero illustration"
          className="w-full h-auto max-w-md"
        />
      </motion.div>

      {/* Right side – headline + CTA */}
      <div className="flex flex-col justify-center">
        <h1 className="text-4xl md:text-6xl font-bold tracking-tighter leading-none">
          Asymmetric Design, Unified Brand
        </h1>
        <p className="mt-4 text-lg text-gray-600 max-w-[65ch]">
          Deliver a premium experience that adapts from wide-screen canvases
          down to a clean, single-column mobile flow.
        </p>
        <a
          href="#"
          className="mt-6 inline-block bg-indigo-600 text-white py-3 px-6 rounded-md hover:bg-indigo-700 transition"
        >
          Get Started
        </a>
      </div>
    </section>
  );
}

```

**Why this works:** `grid-cols-1 md:grid-cols-2` creates the asymmetric split on desktop while defaulting to a single column below Tailwind's `md:` threshold of 768 px. The `min-h-[100dvh]` utility prevents iOS address-bar jump, and `max-w-[1400px] mx-auto` centers the content without forcing a fixed-width hero.

### Multi-Column Feature Grid with Explicit Collapse

This [`src/components/FeatureGrid.tsx`](https://github.com/Leonxlnx/taste-skill/blob/main/src/components/FeatureGrid.tsx) pattern adheres to the mobile-first collapse rule by defining `grid-cols-1 md:grid-cols-3` so the asymmetric three-column desktop layout falls back seamlessly to one column on small viewports.

```tsx
/*  src/components/FeatureGrid.tsx  */
"use client";

export function FeatureGrid({ items }: { items: {title: string; desc: string; img: string;}[] }) {
  return (
    <section className="max-w-[1400px] mx-auto px-4 py-16">
      <div className="grid grid-cols-1 md:grid-cols-3 gap-10">
        {items.map((item, i) => (
          <div key={i} className="flex flex-col items-start">
            <img src={item.img} alt={item.title} className="w-full h-auto rounded-md" />
            <h3 className="mt-4 text-2xl font-medium">{item.title}</h3>
            <p className="mt-2 text-gray-600">{item.desc}</p>
          </div>
        ))}
      </div>
    </section>
  );
}

```

**Key implementation detail:** Because the grid uses explicit fractional columns rather than `calc()` width hacks, it satisfies the grid-over-flex directive from [`skills/taste-skill/SKILL.md`](https://github.com/Leonxlnx/taste-skill/blob/main/skills/taste-skill/SKILL.md) §3.5. The collapse behavior is declared in the same component, matching the explicit fallback rule in [`skills/taste-skill/SKILL.md`](https://github.com/Leonxlnx/taste-skill/blob/main/skills/taste-skill/SKILL.md) §4.6.

### Full-Height Section Without h-screen

The [`src/components/FullHeightBanner.tsx`](https://github.com/Leonxlnx/taste-skill/blob/main/src/components/FullHeightBanner.tsx) snippet replaces the banned `h-screen` class with the framework-approved `min-h-[100dvh]`.

```tsx
/*  src/components/FullHeightBanner.tsx  */
"use client";

export function FullHeightBanner() {
  return (
    <section className="min-h-[100dvh] flex items-center justify-center bg-gray-50 dark:bg-gray-900">
      <h2 className="text-5xl font-bold text-center">
        Full-Height, No Scroll Jank
      </h2>
    </section>
  );
}

```

Using `min-h-[100dvh]` guarantees viewport stability on mobile browsers where `100vh` can trigger unexpected scroll or resize events.

## Source Files That Define These Rules

- [`skills/taste-skill/SKILL.md`](https://github.com/Leonxlnx/taste-skill/blob/main/skills/taste-skill/SKILL.md) — Contains the core design system, including the mobile-collapse guidance, the grid-over-flex prohibition, and the viewport-stability directive in §3.5 and §4.6.
- [`skills/stitch-skill/SKILL.md`](https://github.com/Leonxlnx/taste-skill/blob/main/skills/stitch-skill/SKILL.md) — Houses the mobile-first collapse rule (§7.2) and the asymmetric layout threshold (§6.2) that bans centered heroes when variance exceeds 4.
- [`README.md`](https://github.com/Leonxlnx/taste-skill/blob/main/README.md) — Outlines the three-dial architecture that drives variance, motion, and density decisions across the framework.

## Summary

- Set **DESIGN_VARIANCE to 4 or higher** to force asymmetric splits instead of centered heroes.
- Use **CSS Grid with explicit Tailwind breakpoints** such as `md:grid-cols-2` or `md:grid-cols-3`, and always pair them with `grid-cols-1` fallbacks.
- Never use **`h-screen`**; always use **`min-h-[100dvh]`** to prevent mobile layout jumping.
- Avoid **`calc()` percentage hacks** and flexbox width math—grid fractions collapse cleanly.
- **Wrap sections in `max-w-[1400px] mx-auto`** to keep asymmetric layouts centered without fixed-width constraints.

## Frequently Asked Questions

### What breakpoint does the Taste Skill framework use for mobile collapse?

The framework uses **768 px** as the hard switch point. According to [`skills/stitch-skill/SKILL.md`](https://github.com/Leonxlnx/taste-skill/blob/main/skills/stitch-skill/SKILL.md) §7.2, all multi-column layouts must collapse to a single column below this width. In Tailwind CSS, this maps directly to the `md:` breakpoint.

### Why does the repository ban centered hero sections for asymmetric layouts?

Centered heroes are explicitly banned when `DESIGN_VARIANCE` exceeds 4 because they enforce visual symmetry. Per [`skills/stitch-skill/SKILL.md`](https://github.com/Leonxlnx/taste-skill/blob/main/skills/stitch-skill/SKILL.md) §6.2, the system must instead emit split-screen, left-aligned, or asymmetric whitespace layouts to maintain the intended variance dial.

### Why is h-screen banned in favor of min-h-[100dvh]?

`h-screen` maps to `100vh`, which causes layout jump on iOS Safari as the dynamic address bar expands and contracts. The [`skills/taste-skill/SKILL.md`](https://github.com/Leonxlnx/taste-skill/blob/main/skills/taste-skill/SKILL.md) §3.5 rule requires `min-h-[100dvh]` to fill the visible viewport using dynamic units, eliminating scroll jank.

### Can I use Flexbox instead of CSS Grid under these rules?

No. [`skills/taste-skill/SKILL.md`](https://github.com/Leonxlnx/taste-skill/blob/main/skills/taste-skill/SKILL.md) §3.5 explicitly requires CSS Grid over Flexbox math and prohibits `calc()` percentage hacks. Grid provides deterministic, fraction-based columns that collapse predictably at the 768 px breakpoint without manual width calculations.
