| description | Best-practice design system and rules for building highly professional, visual training/course slide decks with python-pptx (Tertiary Infotech house style). Use whenever creating or polishing a .pptx deck so the result is clean, white-theme, visual, and consistent — large readable fonts, brand colours, icon/card layouts, screenshots and diagrams instead of walls of text. Pair with the tertiary-course-slides skill. |
PPT Design & Presentation — Best Practices
Apply these when generating or refining a course/training deck (python-pptx).
Theme & format
- 16:9 (13.333 × 7.5 in). All-white slides — never dark/black backgrounds.
- Font: Arial for every run. Brand colours: blue
#1F6FEB, teal #10B981, ink #161B26, grey #5B6372, violet #7C3AED, light #F5F8FC.
- Cover with the course title + n8n & Tertiary Infotech Academy logos + UEN; footer on every content slide = course/code (left),
© 2026 Tertiary Infotech Academy Pte Ltd (center), slide number (right).
Typography (make it presentable — large fonts)
- Slide title ≈ 28–30 pt, kicker label ≈ 14 pt (brand colour, uppercase).
- Body bullets ≈ 18–20 pt (never below 16 pt). Two-column body ≈ 17 pt. Card body ≈ 14 pt.
- Section dividers: title ≈ 40 pt, big faint topic number ≈ 72 pt.
- Step slides: one step, big numbered circle + step text ≈ 24 pt.
Be visual, not wordy
- ≤ 5 bullets per slide, one idea per bullet. Split dense slides.
- Prefer layouts over paragraphs:
- 3 colour cards for "features / why / pillars" (heading + 3 short lines each).
- Two-column for comparisons (GET vs POST, model vs memory, in-memory vs Pinecone).
- Big-statement slides (one large sentence) to punctuate sections.
- Screenshot slides: real product screenshots (websites, the n8n canvas) beside short steps.
- Diagrams: redraw concepts in the brand theme (e.g. a RAG flow) — never paste watermarked images.
- Add a workflow screenshot for every hands-on activity; a gallery for sample student work.
Structure of a course deck
- Cover → admin (digital attendance/TRAQOM, trainer, ground rules, lesson plan, learning outcomes, assessment).
- Per topic: a section divider, concept slides (what / why / how, with cards & comparisons), then per activity: overview → workflow screenshot → one-step-per-slide → green "Test it".
- Lunch/tea-break divider slides; recap slides at the end of each day; a Thank-You close.
Consistency & alignment
- Activity titles and topic numbering must match the Learner Guide and Lesson Plan exactly.
- Reuse helper functions (
content, two_col, cards3, website_slide, gallery_slide, img_slide, big_statement, section, step_slide) so spacing/fonts stay uniform.
Implementation lives in the tertiary-course-slides skill (make_slides.py).
