# Responsive Picture / srcset Art Direction Builder

Build complete markup with art-directed crops: per-breakpoint  elements, 1x/2x density candidates or {w}-template width descriptors, optional AVIF/WebP format layers, sizes handling, CLS-safe width/height, plus HTML and JSX flavors with spec-based lint notes.

## Overview

The Responsive Picture / srcset Art Direction Builder generates standards-compliant HTML and React JSX \`\` markup for art-directed image crops across custom breakpoints. It automatically ladders media queries from largest to smallest, configures pixel density (1x/2x) or resource width (\`w\`) descriptors, scaffolds modern AVIF and WebP format layers, and includes layout shift prevention and spec linting.

## Inputs

- **Art-direction sources (one per line: minWidth URL \[widths\])** (textarea): 1280 /img/hero-wide.jpg 768 /img/hero-mid.jpg 0 /img/hero-mobile.jpg
- **Optional: upload crop variants instead (up to 6 images)** (file): Optional — upload the narrow crop, mid crop, wide crop…
- **Descriptor mode** (select)
- **Densities** (text): 1x,2x
- **sizes attribute (w mode)** (text): (min-width: 1024px) 960px, 100vw
- **Fallback URL** (text): /img/hero-mobile.jpg
- **Alt text** (text): Fresh sourdough loaves on a marble counter
- **Format layer** (select)
- **Markup flavor** (select)
- **Add loading/decoding attributes** (checkbox)

## When to use

- You need distinct image aspect ratios or crops across mobile, tablet, and desktop viewports using art direction.
- You want to deliver next-gen image formats like AVIF and WebP with reliable JPEG or PNG fallbacks.
- You need clean HTML or React JSX image code with proper `sizes`, `srcset`, and lazy loading attributes without manual formatting errors.

## How it works

- Define art-directed breakpoint rules by entering minimum widths alongside image URLs or uploading variant image files.
- Select your descriptor strategy (pixel density multipliers like 1x/2x or width descriptors using `{w}` templates with sizes queries).
- Choose format layers (AVIF, WebP, or original) and output flavor (HTML or React JSX with camelCase attributes).
- The tool sorts media queries in descending order, constructs the \`\` ladder, and provides lint notes highlighting potential spec or layout issues.

## Use cases

- Generating responsive hero banners with landscape crops for desktop and tight vertical crops for mobile screens.
- Configuring CDN-backed responsive image pipelines using dynamic `{w}` width parameter templates.
- Migrating static site image tags to modern, multi-format \`\` elements to optimize Core Web Vitals and PageSpeed scores.

## Frequently asked questions

### Why does the tool automatically reorder breakpoint sources?

Browsers evaluate \`\` elements in top-down order and use the first matching rule. Sorting from largest to smallest \`min-width\` ensures desktop viewports match before smaller tablet and mobile fallbacks.

### What is the difference between density mode and width mode?

Density mode generates fixed multiplier candidates (e.g., 1x, 2x) for fixed-size graphics, while width mode pairs `{w}` resource widths with layout `sizes` so browsers select optimal files based on dynamic display width.

### How does format layering work?

Selecting AVIF or AVIF + WebP layers adds preceding \`\` elements with swapped file extensions before standard fallback sources, enabling modern browser compression while maintaining compatibility.

### Does this generator produce React-compatible markup?

Yes. Switching the flavor setting to JSX converts attributes such as \`srcset\` to \`srcSet\` and outputs self-closing \`\` and \`\` tags.

### What performance attributes are added by default?

When lazy attributes are enabled, the fallback \`\` includes \`loading="lazy"\` and \`decoding="async"\` to improve initial page load performance.
