HTML PPT — Editorial Minimalism
A 16:9 deck for the briefs that hate neon: investor updates, design reviews, internal manifestos, lecture decks. Reads like a print supplement, not a SaaS landing.
Source
Distilled from Leonxlnx/taste-skill — skills/minimalist-skill/SKILL.md. The deck system follows the existing project convention from design-templates/html-ppt-pitch-deck/example.html (each .slide is a 100vw × 100vh section; opened directly, slides stack vertically). See example.html in this directory.
Hard rules
Substrate: warm off-white #FBFBFA / #F7F6F3. Foreground off-black #1A1A19. Never pure white or pure black.
Type pairing: display in serif (Instrument Serif / Newsreader / Lyon), body in grotesque (Inter Tight / Switzer), meta in mono (JetBrains Mono).
Display scale per slide: title clamp(56px, 6.5vw, 96px) italic-capable serif, line-height 1.05, tracking -0.025em.
Hairline only:1px solid #EAEAEA — borders, dividers, table cells. No drop shadows.
One accent color chosen from the muted-pastel pairs (e.g. sage #346538 on #EDF3EC, or red #9F2F2D on #FDEBEC). Used sparingly — eyebrow dot, chart fill, call-out chip. Never as a slide background.
Slide padding: generous (72px 96px minimum). Title at most 14ch wide.
Eyebrow: every slide opens with a mono uppercase eyebrow letter-spacing: 0.18em and a section number 01 / 09.
Page numbers: mono, bottom-right corner.
Banned
Inter (use Inter Tight if you must, but prefer Switzer / SF Pro). No Roboto, Open Sans.
Heavy drop shadows. Glow. Gradient text.
3-equal-card feature rows. Use uneven hairline-divided columns instead.
Emojis in text or as bullet markers — use — or no marker.
Full-bleed photography on every slide. Use one or two image slides; reserve them.
