.ppt or .pptx slides into an HTML presentationBefore generating, read STYLE_PRESETS.md for the viewport-safe CSS base, density limits, preset catalog, and CSS gotchas.
Choose one path:
.ppt or .pptxAsk only the minimum needed:
If the user has content, ask them to paste it before styling.
Default to visual exploration.
If the user already knows the desired preset, skip previews and use it directly.
Otherwise:
.ecc-design/slide-previews/.Use the preset guide in STYLE_PRESETS.md when mapping mood to style.
Output either:
presentation.html[presentation-name].htmlUse an assets/ folder only when the deck contains extracted or user-supplied images.
Required structure:
STYLE_PRESETS.mdTreat this as a hard gate.
Rules:
.slide must use height: 100vh; height: 100dvh; overflow: hidden;clamp()Use the density limits and mandatory CSS block in STYLE_PRESETS.md.
Check the finished deck at these sizes:
If browser automation is available, use it to verify no slide overflows and that keyboard navigation works.
At handoff:
Use the correct opener for the current OS:
open file.htmlxdg-open file.htmlstart "" file.htmlFor PowerPoint conversion:
python3 with python-pptx to extract text, images, and notes.python-pptx is unavailable, ask whether to install it or fall back to a manual/export-based workflow.Keep conversion cross-platform. Do not rely on macOS-only tools when Python can do the job.
Include:
main, section, nav)prefers-reduced-motionUse these maxima unless the user explicitly asks for denser slides and readability still holds:
| Slide type | Limit |
|---|---|
| Title | 1 heading + 1 subtitle + optional tagline |
| Content | 1 heading + 4-6 bullets or 2 short paragraphs |
| Feature grid | 6 cards max |
| Code | 8-10 lines max |

--- name: frontend-slides description: Create stunning, animation-rich HTML presentations from scratch or by converting PowerPoint files. Use when the user wants to build a presentation, convert a PPT/PPTX to web, or create slides for a talk/pitch. Helps non-designers discover their aesthetic through visual exploration rather than abstract choices. origin: ECC --- # Frontend Slides Create zero-dependency, animation-rich HTML presentations that run entirely in the browser. Inspired by the visual exploration approach showcased in work by [zarazhangrui](https://github.com/zarazhangrui). ## When to Activate - Creating a talk deck, pitch deck, workshop deck, or internal presentation - Converting `.ppt` or `.pptx` slides into an HTML presentation - Improving an existing HTML presentation's layout, motion, or typography - Exploring presentation styles with a user who does not know their design preference yet ## Non-Negotiables 1. **Zero dependencies**: default to one self-contained HTML file with inline CSS and JS. 2. **Viewport fit is mandatory**: every slide must fit inside one viewport with no internal scrolling. 3. **Show, don't tell**: use visual previews instead of abstract style questionnaires. 4. **Distinctive design**: avoid generic purple-gradient, Inter-on-white, template-looking decks. 5. **Production quality**: keep code commented, accessible, responsive, and performant. Before generating, read `STYLE_PRESETS.md` for the viewport-safe CSS base, density limits, preset catalog, and CSS gotchas. ## Workflow ### 1. Detect Mode Choose one path: - **New presentation**: user has a topic, notes, or full draft - **PPT conversion**: user has `.ppt` or `.pptx` - **Enhancement**: user already has HTML slides and wants improvements ### 2. Discover Content Ask only the minimum needed: - purpose: pitch, teaching, conference talk, internal update - length: short (5-10), medium (10-20), long (20+) - content state: finished copy, rough notes, topic only If the user has content, ask them to paste it before styling. ### 3. Discover Style Default to visual exploration. If the user already knows the desired preset, skip previews and use it directly. Otherwise: 1. Ask what feeling the deck should create: impressed, energized, focused, inspired. 2. Generate **3 single-slide preview files** in `.ecc-design/slide-previews/`. 3. Each preview must be self-contained, show typography/color/motion clearly, and stay under roughly 100 lines of slide content. 4. Ask the user which preview to keep or what elements to mix. Use the preset guide in `STYLE_PRESETS.md` when mapping mood to style. ### 4. Build the Presentation Output either: - `presentation.html` - `[presentation-name].html` Use an `assets/` folder only when the deck contains extracted or user-supplied images. Required structure: - semantic slide sections - a viewport-safe CSS base from `STYLE_PRESETS.md` - CSS custom properties for theme values - a presentation controller class for keyboard, wheel, and touch navigation - Intersection Observer for reveal animations - reduced-motion support ### 5. Enforce Viewport Fit Treat this as a hard gate. Rules: - every `.slide` must use `height: 100vh; height: 100dvh; overflow: hidden;` - all type and spacing must scale with `clamp()` - when content does not fit, split into multiple slides - never solve overflow by shrinking text below readable sizes - never allow scrollbars inside a slide Use the density limits and mandatory CSS block in `STYLE_PRESETS.md`. ### 6. Validate Check the finished deck at these sizes: - 1920x1080 - 1280x720 - 768x1024 - 375x667 - 667x375 If browser automation is available, use it to verify no slide overflows and that keyboard navigation works. ### 7. Deliver At handoff: - delete temporary preview files unless the user wants to keep them - open the deck with the platform-appropriate opener when useful - summarize file path, preset used, slide count, and easy theme customization points Use the correct opener for the current OS: - macOS: `open file.html` - Linux: `xdg-open file.html` - Windows: `start "" file.html` ## PPT / PPTX Conversion For PowerPoint conversion: 1. Prefer `python3` with `python-pptx` to extract text, images, and notes. 2. If `python-pptx` is unavailable, ask whether to install it or fall back to a manual/export-based workflow. 3. Preserve slide order, speaker notes, and extracted assets. 4. After extraction, run the same style-selection workflow as a new presentation. Keep conversion cross-platform. Do not rely on macOS-only tools when Python can do the job. ## Implementation Requirements ### HTML / CSS - Use inline CSS and JS unless the user explicitly wants a multi-file project. - Fonts may come from Google Fonts or Fontshare. - Prefer atmospheric backgrounds, strong type hierarchy, and a clear visual direction. - Use abstract shapes, gradients, grids, noise, and geometry rather than illustrations. ### JavaScript Include: - keyboard navigation - touch / swipe navigation - mouse wheel navigation - progress indicator or slide index - reveal-on-enter animation triggers ### Accessibility - use semantic structure (`main`, `section`, `nav`) - keep contrast readable - support keyboard-only navigation - respect `prefers-reduced-motion` ## Content Density Limits Use these maxima unless the user explicitly asks for denser slides and readability still holds: | Slide type | Limit | |------------|-------| | Title | 1 heading + 1 subtitle + optional tagline | | Content | 1 heading + 4-6 bullets or 2 short paragraphs | | Feature grid | 6 cards max | | Code | 8-10 lines max | | Quote | 1 quote + attribution | | Image | 1 image constrained by viewport | ## Anti-Patterns - generic startup gradients with no visual identity - system-font decks unless intentionally editorial - long bullet walls - code blocks that need scrolling - fixed-height content boxes that break on short screens - invalid negated CSS functions like `-clamp(...)` ## Related ECC Skills - `frontend-patterns` for component and interaction patterns around the deck - `liquid-glass-design` when a presentation intentionally borrows Apple glass aesthetics - `e2e-testing` if you need automated browser verification for the final deck ## Deliverable Checklist - presentation runs from a local file in a browser - every slide fits the viewport without scrolling - style is distinctive and intentional - animation is meaningful, not noisy - reduced motion is respected - file paths and customization points are explained at handoff
