Styling Philosophy: Minimal Intervention

Core principle: Style only what's necessary. Let WordPress themes handle defaults.

CRITICAL: Read docs/12-migration-rules.md for comprehensive typography and styling rules.

Typography Rules (CRITICAL)

Headings (h1-h6) - NEVER SET:

• fontSize - theme handles heading sizes (even responsive ones)
• fontWeight - theme handles heading weights
• color - theme handles text colors (unless on dark background)
• lineHeight - theme handles heading line-heights

Headings - OKAY TO SET:

• marginTop, marginBottom - for spacing control
• textAlign - for layout/centering

WRONG - Over-styled heading:

{"tag": "h2", "styleAttributes": {"fontSize": ["3rem"], "fontWeight": ["700"]}}

CORRECT - Minimal heading:

{"tag": "h2", "styleAttributes": {"marginBottom": ["1rem"], "textAlign": ["center"]}}

Paragraphs and text - NEVER SET:

• color - unless on dark/colored background
• fontWeight: ["400"] - it's the default, don't set it
• lineHeight - unless custom fontSize requires adjustment

Paragraphs and text - OKAY TO SET:

• fontSize - ONLY for intentional accent/lead text (e.g., ["1.2rem"])
• fontFamily - for specific font choices
• fontWeight: ["700"] - for intentionally bold body text

Exception - Text on dark backgrounds: When text is over a dark background (hero overlays, dark sections, card overlays):

• White text: "color":["var(--wp--preset--color--white, #ffffff)"]
• Semi-transparent white: "color":["rgba(255,255,255,0.9)"]

Semantic Heading Hierarchy

Use proper HTML heading levels:

h1 - Page title (usually in theme header)
h2 - Main section titles (one per section)
h3 - Subsection/card titles
h4 - Minor headings within cards

Background Colors - Use Theme Palette

WRONG - Generic variables:

"backgroundColor": ["var(--wp--preset--color--white, #ffffff)"]
"backgroundColor": ["var(--wp--preset--color--light-grey, #f8f8f8)"]

CORRECT - Theme palette:

"backgroundColor": ["var(--wp--preset--color--palette-color-6, var(--theme-palette-color-6, #f5f5f4))"]
"backgroundColor": ["var(--wp--preset--color--palette-color-7, var(--theme-palette-color-7, #fafaf9))"]
"backgroundColor": ["var(--wp--preset--color--palette-color-8, var(--theme-palette-color-8, #fffffe))"]

What TO Style:

• Structural - flexbox layouts, positioning, display modes
• Spacing - section padding, gaps between columns (using CSS variables)
• Text on dark backgrounds - white/light colors for readability
• Backgrounds - using theme palette variables

What NOT to Style:

• fontSize on headings (h1-h6) - theme handles sizes
• color on headings/paragraphs - theme colors cascade
• fontWeight: 400 - don't set normal weight explicitly
• lineHeight unless specifically needed

CSS Variables vs Hardcoded

• Prefer CSS variables for spacing: var(--wp--preset--spacing--60)
• Prefer palette colors for backgrounds: var(--wp--preset--color--palette-color-7, ...)
• AVOID generic colors: var(--wp--preset--color--white), var(--wp--preset--color--light-grey)

Block Types Guide

Always Use GreenLight Element

Use greenshift-blocks/element for most content:

Old Block (AVOID)	Replace With
greenshift-blocks/row	greenshift-blocks/element with tag:"section", align:"full"
greenshift-blocks/row-column	greenshift-blocks/element with type:"inner"
greenshift-blocks/heading	greenshift-blocks/element with tag:"h1-h6", textContent

Specialized Blocks (OK to use)

• greenshift-blocks/element - Primary block for everything
• greenshift-blocks/swiper - Slider/carousel
• greenshift-blocks/querygrid - Query loop for posts

---

Critical Rules

1. Block IDs: Unique id starting with gsbp- + 7 alphanumeric chars. localId MUST match id.

2. Content Types (type parameter):

   • "text": Text-only blocks - requires textContent with duplicated text
   • "inner": Container blocks - wrap plain text in <span> element blocks
   • "no": Empty/spacer elements

3. Styling (styleAttributes):

   • NEVER use inline style="..." attributes
   • Properties use camelCase (e.g., backgroundColor, paddingTop)
   • Values are arrays: ["desktop", "tablet", "mobile_l", "mobile_p"]
   • Single value ["10px"] applies to all breakpoints
   • If styleAttributes exists, add localId to HTML class attribute

4. Images:

   • Always loading="lazy"
   • Use https://placehold.co/WIDTHxHEIGHT for placeholders
   • originalWidth and originalHeight in JSON MUST have matching width and height HTML attributes

5. SVG Icons: Unicode encode SVG content in icon.icon.svg:

   • < = \u003c
   • > = \u003e
   • " = \u0022

6. Links: Use tag: "a" with href. For external: linkNewWindow: true

Page Structure Patterns

Page Wrapper (for multi-section pages)

ALWAYS wrap full pages in a single container to control spacing:

<!-- wp:greenshift-blocks/element {"id":"gsbp-page001","type":"inner","localId":"gsbp-page001","align":"full","styleAttributes":{"marginBlockStart":["0px"]},"metadata":{"name":"Page Wrapper"}} -->
<div class="gsbp-page001 alignfull">
  <!-- All sections go here -->
</div>
<!-- /wp:greenshift-blocks/element -->

Section Wrapper

<!-- wp:greenshift-blocks/element {"id":"gsbp-XXXXXXX","tag":"section","type":"inner","localId":"gsbp-XXXXXXX","align":"full","styleAttributes":{...},"isVariation":"contentwrapper"} -->
<section class="gsbp-XXXXXXX alignfull">
  <!-- Content Area -->
</section>
<!-- /wp:greenshift-blocks/element -->

Content Area

IMPORTANT: Use content-size (not wide-size) for content width:

"width": ["var(--wp--style--global--content-size, 1290px)"]

Block Generation Workflow

For Simple Elements

1. Determine element type (text, image, button, icon)
2. Set appropriate type parameter
3. Add minimal styling via styleAttributes
4. Add animation if requested
5. Save to HTML file

For Sections

1. Create section wrapper (tag: "section", align: "full", isVariation: "contentwrapper")
2. Add content area container (isVariation: "nocolumncontent")
3. Build inner content hierarchy
4. Apply animations with staggered delays
5. Ensure responsive breakpoints
6. Save to HTML file

For Full Pages

1. Create Page Wrapper with marginBlockStart: ["0px"]
2. Plan section structure
3. Generate each section inside wrapper
4. Maintain consistent styling/spacing
5. Add metadata: {"name": "Section Name"} for editor navigation
6. Save to HTML file

Animation Guidelines

Always use onlyonce: true for entrance animations.

Available types: fade, fade-up, fade-down, fade-left, fade-right, zoom-in, zoom-out, slide-up, clip-right, clip-left, flip-up, flip-down

Recommended Settings

"animation": {"type": "fade-up", "duration": 600, "easing": "ease-out", "onlyonce": true}

Stagger Pattern

Element	Delay
Heading	0ms
Subheading	150ms
Description	300ms
Button	450ms
Cards (grid)	+150ms each

---

Responsive Breakpoints

Array order: ["desktop", "tablet", "mobile_landscape", "mobile_portrait"]

Example:

"fontSize": ["var(--wp--preset--font-size--giant)", "var(--wp--preset--font-size--giga)", "var(--wp--preset--font-size--grand)", "var(--wp--preset--font-size--xxl)"]

Quality Checklist

Before saving output:

Structure & IDs:

• Every block has unique gsbp-XXXXXXX ID
• localId matches id for EVERY block
• NO inline style attributes ANYWHERE
• class includes localId when styleAttributes present
• Section > Content Area > Elements hierarchy

Typography (CRITICAL):

• NO fontSize on headings (h1-h6)
• NO fontWeight on headings (h1-h6)
• NO color on text (unless on dark background)
• NO fontWeight: ["400"] anywhere
• Proper heading hierarchy (h2 → h3 → h4)

Images:

• Images have loading="lazy"
• Images have width and height HTML attributes matching JSON params

SVG Icons:

• SVG content uses Unicode escapes: \u003c, \u003e, \u0022

Styling:

• Minimal styling - only what's necessary
• CSS variables used where appropriate
• Background colors use palette variables (palette-color-X)
• Responsive arrays for key dimensions

Output

1. Generate the complete Greenshift block HTML code
2. Ask user for filename or suggest one based on content (e.g., hero-section.html, landing-page.html)
3. SAVE the code to an HTML file using the Write tool
4. Confirm the file location to the user

IMPORTANT: Always save output to a .html file. Never just display the code in chat.
