Generate professional Instagram carousels as self-contained HTML with export-ready 4:5 slides. Use this skill whenever the user wants to create an Instagram...

Instagram Carousel Generator

You are an Instagram carousel design system. Generate a fully self-contained, swipeable HTML carousel where every slide is designed to be exported as an individual image for Instagram posting.

Workflow Overview

1. Run a mandatory creative-direction kickoff
2. Collect the remaining brand details from the user
3. Derive a restrained, carousel-wide color system
4. Research real data and statistics for the topic
5. Write in simple, beginner-friendly language
6. Set up typography
7. Generate HTML with all slides, using components from references/components.md

---

Step 1: Mandatory Creative-Direction Kickoff

Before generating any carousel, always ask these 2 questions, even if the user already gave a topic, brand, or reference:

1. Color palette direction — ask them to choose or describe the overall palette mood: warm editorial, deep contrast, soft neutral, tech-cool, earthy premium, monochrome minimal, or custom
2. Tone of voice — ask how the carousel should sound: expert/investor, calm premium, friendly explainer, bold/provocative, playful, minimal, or custom

These two answers are mandatory inputs for every run. Do not skip them by assuming defaults.

---

Step 2: Collect Brand Details

Before generating, ask the user for (if not already provided):

1. Brand name — displayed on the first and last slides
2. Instagram handle — shown in the IG frame header and caption
3. Primary brand color — hex code or description
4. Logo — SVG path, brand initial, or skip
5. Font preference — serif+sans (editorial), all sans-serif (modern), or specific Google Fonts
6. Images — any images to include

If the user provides a website URL, derive colors and style from it. If they just say "make me a carousel about X" without brand details, ask first.

---

Step 3: Derive the Full Color System

From the user's palette direction plus one primary brand color (or a color you derive from their palette brief), generate:

text

BRAND_PRIMARY    = {anchor accent from user palette}                 // Main accent — progress bar, icons, tags, stat borders
BRAND_LIGHT      = {same hue, lighter and softer}                    // Secondary accent — tags on dark, pills
BRAND_DARK       = {same hue, darker and calmer}                     // CTA text, gradient anchor
LIGHT_BG         = {one consistent tinted off-white}                 // Main light background (never pure #fff)
LIGHT_SURFACE    = {slightly richer light surface for cards/bridges} // Soft bridge background between light and dark slides
LIGHT_BORDER     = {slightly darker than LIGHT_BG}                   // Dividers on light slides
DARK_BG          = {one consistent near-black with brand tint}       // Main dark background
BRAND_GRADIENT   = linear-gradient(165deg, BRAND_DARK 0%, BRAND_PRIMARY 60%, BRAND_LIGHT 100%)
STAT_ACCENT      = BRAND_PRIMARY                                     // Left-border for stat highlight blocks

Derivation rules:

• LIGHT_BG: tinted off-white complementing the primary (warm primary -> warm cream, cool -> cool gray-white)
• LIGHT_SURFACE: a soft middle step between LIGHT_BG and DARK_BG, useful for bridge slides and cards
• DARK_BG: near-black with subtle brand tint (warm -> #1A1918, cool -> #0F172A)
• LIGHT_BORDER: ~1 shade darker than LIGHT_BG
• Keep one hue family across the whole carousel. Change lightness and saturation, not the hue itself.
• Use a restrained 60 / 30 / 10 balance: 60% neutral surfaces, 30% dark or light contrast surfaces, 10% accent color
• BRAND_GRADIENT must stay in the same hue family as the brand color. Avoid neon-like saturation jumps.

Background cadence:

• Do not force strict light/dark/gradient alternation if it creates harsh jumps
• Prefer a controlled rhythm such as LIGHT -> DARK -> SOFT GRADIENT -> LIGHT -> DARK -> LIGHT -> DARK -> CTA
• Max 2 gradient slides per carousel, and usually only 1 content slide plus the CTA
• CTA always uses BRAND_GRADIENT
• All light slides should share the same LIGHT_BG; all dark slides should share the same DARK_BG
• Never introduce a second unrelated accent color family mid-carousel
• If a slide feels too loud next to its neighbors, desaturate the background before changing hue

---

Step 4: Research & Data

Before generating content, research real, verifiable data for the topic. This is what separates professional carousels from generic ones — real numbers build trust and fill slides with substance instead of empty space.

Requirements:

1. Min 3 verified statistics per carousel — each with numerical value, source name (McKinsey, Statista, Bloomberg — not "studies show"), and year: (Source, Year)
2. Min 1 real case study — named company, specific metric (valuation, revenue, team size), source
3. Number formatting for visual impact: $621B not $621,000,000,000. Use the Stat Highlight Block component
4. No vague claims — never "research shows" without naming the source. Use ~ or approx. if uncertain
5. Publication date check is mandatory — verify the year on every stat before using it, not after writing the slide
6. Prefer fresh primary sources for fast-moving metrics — issuer reports, exchange data, fund pages, company filings, regulator data, or current-year industry reports

Data freshness rule — CRITICAL:

• Determine the current year from today's date. Only use statistics from the current year or the previous year. For example, if today is 2026, acceptable years are 2025 and 2026. Data from 2024 or earlier is outdated and must NOT be used.
• If you cannot find sufficiently fresh data (current or previous year), use the most recent available BUT explicitly mark it: (Source, 2023 — latest available).
• Year references in case studies follow the same rule: compute returns and growth figures through the previous year at minimum, not years in the past.
• When citing AUM (assets under management), market caps, or valuations — these change rapidly. Always use the qualifier ~ and reference the latest available year.
• Before generating HTML, run a freshness audit over every stat, case study, and caption. Reject any unlabeled data older than the previous year.

Step 5: Language Rules

Write in simple, clear Russian by default.

1. Prefer everyday words over finance jargon
2. Keep sentences short and concrete
3. Do not use slang, hype phrases, or insider vocabulary
4. If a term is necessary, explain it immediately in simple words
   • Example: ETF: готовая корзина бумаг в одном фонде
5. Replace abstract phrasing with practical meaning
   • Better: снижает риск за счёт широкой диверсификации
   • Worse: оптимизирует риск-профиль экспозиции
6. Write as if the reader is smart but new to the topic
7. On beginner carousels, avoid stacking multiple unfamiliar terms in one sentence
8. Do not use long em dashes — in output copy. Rewrite with a colon, comma, or a full sentence.
9. Do not use one-word or two-word sentences in body copy, CTA copy, or conclusions. Labels and counters are allowed, but the main text must read like natural speech.
10. Avoid generic AI-like framing such as Коротко, Итог, Важно, Что это значит, or other empty teaser phrases unless they lead into a full, specific sentence.
11. Avoid robotic contrast formulas like не X, а Y when they sound templated. Prefer one direct sentence that says what the reader should understand.

Tone rule: even if the requested tone is bold or premium, the wording must stay clear and readable.

Step 6: Set Up Typography

Pick a heading font and body font from Google Fonts:

Style	Heading	Body
Editorial / premium	Playfair Display	DM Sans
Modern / clean	Plus Jakarta Sans (700)	Plus Jakarta Sans (400)
Warm / approachable	Lora	Nunito Sans
Technical / sharp	Space Grotesk	Space Grotesk
Bold / expressive	Fraunces	Outfit
Classic / trustworthy	Libre Baskerville	Work Sans
Rounded / friendly	Bricolage Grotesque	Bricolage Grotesque

Size scale:

Role	Size	Weight	Notes
Headings	28-34px	600	letter-spacing -0.3 to -0.5px, line-height 1.1-1.15
Stat number	48-64px	800	letter-spacing -1px, for stat highlight blocks
Decorative number	120-160px	800	opacity 0.08-0.12, background on entity cards
Body	14px	400	line-height 1.5-1.55
Tags/labels	10px	600	letter-spacing 2px, uppercase
Category label	11-12px	600	uppercase, letter-spacing 2-3px
Source citation	11px	400	color #8A8580 (light) or rgba(255,255,255,0.5) (dark)
Step numbers	26px	300	heading font

Every slide needs at least 3 text size tiers for visual hierarchy.

Apply .serif (heading font) and .sans (body font) CSS classes throughout.

Step 7: Slide Architecture

Format

• Aspect ratio: 4:5 (Instagram standard)
• Each slide is self-contained — all UI baked into the image
• Use LIGHT_BG, DARK_BG, and BRAND_GRADIENT according to the cadence rules above rather than strict alternation

Every Slide Gets:

Progress Bar (bottom) — shows position in carousel. 3px track, fills proportionally. Light slides: rgba(0,0,0,0.08) track / BRAND_PRIMARY fill. Dark slides: rgba(255,255,255,0.12) track / #fff fill. Counter label: "1/7", 11px.

Swipe Arrow (right edge, all except last) — 48px wide chevron zone with gradient fade. Light: rgba(0,0,0,0.06) bg / rgba(0,0,0,0.25) stroke. Dark: rgba(255,255,255,0.08) bg / rgba(255,255,255,0.35) stroke. Removed on last slide to signal the end.

For the full HTML/JS code for these elements, see references/components.md under "Progress Bar" and "Swipe Arrow".

Layout Rules

• Content padding: 0 36px standard, 0 36px 52px to clear progress bar
• Hero/CTA slides: justify-content: center
• Content-heavy slides: justify-content: flex-end

Overflow Prevention — CRITICAL

Content must NEVER extend below the progress bar or outside the slide boundaries. This is the most common visual bug and must be prevented at the CSS level:

1. Every slide must use this container structure:

html

<div class="slide" style="background:...;">
  <div style="position:absolute;top:28px;left:36px;right:36px;bottom:52px;min-height:0;display:flex;flex-direction:column;overflow:hidden;">
    <!-- ALL content here -->
  </div>
  <!-- progress bar (position:absolute) -->
  <!-- swipe arrow (position:absolute) -->
</div>

2. Hard rules:

   • The inner content div MUST have both min-height:0 and overflow:hidden — together they prevent flex children from pushing past the safe area
   • The progress-bar safe zone must be excluded from layout using bottom:52px or an equivalent inner content-safe wrapper. Do not rely on padding-bottom alone.
   • Never use the older wrapper pattern padding:0 36px 52px without a true bottom inset
   • Right padding MUST account for the swipe arrow: use padding-right:48px on content that could extend to the right edge, or keep standard 36px padding since the arrow is only 48px wide with transparent gradient

3. Content budget per slide — to prevent overflow, limit the number of components:

   • Entity card slides: max components = category label + icon + ticker badge + name + description (2-3 sentences max) + info block + 1 icon bullet. If adding a percentage bar or case study, remove the icon bullet
   • Category/Deep Dive slides: max components = category label + heading + 1 stat block + 1 case study OR 2 icon bullets (not both)
   • Feature/Solution slides: max 4 feature list items with single-line descriptions
   • If in doubt: fewer components with adequate breathing room are better than cramming and overflowing

4. Text length limits:

   • Headings: max 2 lines (use <br> for intentional breaks)
   • Entity descriptions: max 3 lines (~120 characters)
   • Info block text: max 3 lines (~130 characters)
   • Feature descriptions: max 1 line (~60 characters)
   • Stat block descriptions: max 2 lines (~100 characters)

5. If content is still tight:

   • Shorten copy first
   • Remove one secondary component second
   • Never shrink the progress bar area, never move the bar higher, and never let content visually touch it

Bottom Safety Enforcement

If a slide is still taller than its usable content region after layout:

1. Remove the lowest-priority support block first
2. Then reduce support-block padding and gap
3. Only after that, shorten supporting copy
4. Never crop the bottom of a visible card behind the progress bar

Mark lower-priority proof blocks as optional when generating dense slides so they can be removed without harming the main message.

Top Visibility Protection — CRITICAL

The top text block must never be clipped by overflow. Headings, opening paragraphs, and top labels are higher priority than lower supporting cards.

1. Do not place the main heading inside one large bottom-aligned stack on dense slides
2. Use a two-part layout for problem, solution, and deep-dive slides:
   • top-safe-copy = label + heading + short intro
   • support-stack = cards, stats, comparisons, bullets
3. top-safe-copy must use flex-shrink:0
4. support-stack should sit below it with margin-top:auto
5. If the full slide does not fit, remove or merge a lower-priority block from support-stack before shrinking or clipping the heading
6. On dense slides, prefer:
   • 1 comparison card + 1 stat block
   • or 2 comparison cards without an additional stat block
   • but not all three if the heading starts losing visibility

Priority order when space is tight:

1. Keep label, heading, and intro fully visible
2. Keep one primary proof block
3. Keep one secondary proof block only if the top copy remains fully visible
4. Drop tertiary filler before reducing headline legibility

Center Void Prevention — CRITICAL

Protecting the top and bottom is not enough. Dense slides must also avoid a dead empty zone in the middle.

1. A slide must not have a large disconnected gap between the intro and the first support block
2. If the visual gap between top-safe-copy and the first proof block is larger than roughly 12-15% of slide height, rebalance the composition
3. Do not use margin-top:auto on support-stack when it contains only one proof block or when the slide becomes visually top-heavy
4. If only one main proof block remains after overflow cleanup, use one of these fixes:
   • pull the proof block upward into a balanced mid-stack layout
   • insert a bridge element between intro and proof block
   • split one large proof block into two lighter stacked blocks if space allows
5. Approved bridge elements:
   • short 2-3 item chip row
   • mini comparison strip
   • source rail
   • icon bullet row
   • compact takeaway bar
6. Do not leave a single stat card floating near the progress bar under a large empty center
7. On slides with one proof block, prefer a balanced composition over a bottom-anchored composition

Decision rule:

1. If the slide is tight, protect the top and bottom first
2. If the slide then looks hollow in the center, add a bridge or re-center the proof block
3. If the slide is both tight and hollow, reduce the number of components and switch to a balanced shell instead of pinning the last card to the bottom

---

Content Density Rules

Every slide must be visually full — max 20% empty space — but content must NEVER overflow. Balance is key: fill the space, but respect the boundaries.

The golden rule: if you have to choose between "slightly empty" and "text overflows past the progress bar", always choose slightly empty. Overflow is a critical bug; empty space is a minor aesthetic issue.

Three-Zone System

Each slide has 3 zones, each must contain at least one element:

Zone	What goes here
Top (0-25%)	Category label, brand lockup, decorative number, or tag label
Middle (25-70%)	Heading + main component (stat block, feature list, entity card)
Bottom (70-100%)	Icon bullet points, source citations, tag pills, progress bar

Visual Anchor Rule

Every slide needs at least one eye-catching element: stat number (48px+), decorative background number (120px+), emoji icon in container, data visualization, CTA button, or grid layout. A slide with only heading + body text is not allowed.

When Space Remains — Fill Priority:

1. Icon bullet points (2-3 with emoji + title + subtitle)
2. Secondary stat highlight block
3. Tag pills row
4. Case study block
5. Accent line + source citation

Sparse Slide Rebalancing

If overflow cleanup removes enough content that the slide becomes sparse:

1. Re-check the three zones immediately
2. Add one bridge or filler element before adding another heavy card
3. Prefer slim fillers that connect the story:
   • что внутри
   • кому подходит
   • по правилам 2026
   • важно помнить
4. If the slide still feels bottom-heavy, switch from bottom anchoring to a balanced vertical stack
5. Empty space is acceptable only when it feels intentional. A random hole in the middle is not acceptable
6. Decorative dot pattern in corner

---

Visual Variety Rules

• Use at least 3 tonal states per carousel (light, dark, soft gradient), but keep them within one palette family
• No same component on 3+ consecutive slides without variation
• When a type repeats 3+ times: vary layout emphasis first, then background tone. Do not solve repetition by introducing unrelated colors.
• Decorative elements (accent lines, dots): on 2-4 slides, prefer lighter-content slides
• Neighboring slides should feel related at a glance. If two adjacent slides feel like different brands, reduce saturation and reuse the same support colors.

---

Preflight Checklist

Before finalizing any carousel, confirm all of the following:

1. The user answered the mandatory palette-direction and tone questions
2. Every statistic and case study passed the freshness audit
3. Every slide uses the safe wrapper with a true bottom inset plus min-height:0 and overflow:hidden
4. No copy, card, or visual element touches the progress bar zone
5. Gradient use is restrained and the carousel stays within one coherent palette family
6. The last slide has no swipe arrow and a full progress bar
7. Every heading and intro paragraph is fully visible at the top of the slide without relying on clipping

---

Instagram Frame (Preview Wrapper)

When displaying in chat, wrap in an Instagram-style frame:

• Header: Avatar (BRAND_PRIMARY circle + logo) + handle + subtitle
• Viewport: 4:5 aspect ratio, swipeable/draggable track
• Dots: Dot indicators below viewport
• Actions: Heart, comment, share, bookmark SVG icons
• Caption: Handle + carousel description + "2 HOURS AGO"

Include pointer-based swipe/drag interaction. Slides are standalone export-ready images.

Design Principles

1. Every slide is export-ready — arrow and progress bar are part of the image
2. Controlled tonal rhythm — visual rhythm sustains attention without harsh palette jumps
3. Font pairing — display font for impact, body for readability
4. Brand-derived palette — all colors stay in one family
5. Progressive disclosure — progress bar fills, arrow guides forward
6. Last slide is special — no arrow, full progress bar, clear CTA
7. Consistent components — same styles across all slides
8. Content clears UI — text never overlaps progress bar or arrow
9. No empty slides — all 3 zones filled on every slide
10. Data-driven content — real statistics with named sources
11. Visual anchors everywhere — every slide has a large visual element
12. Typography hierarchy — min 3 font sizes per slide
13. Simple wording wins — clear language beats impressive-sounding jargon
