Typography — The Voice of Glass

"Typography is the craft of endowing human language with a durable visual form." — Robert Bringhurst, The Elements of Typographic Style

🎯 Filosofi Tipografi

Tipografi BETE dibangun di atas tiga pilar:

  1. Hierarki melalui weight & size — Bukan sekadar memperbesar heading, tapi memberi bobot makna
  2. Ritme vertikal yang konsisten — Setiap elemen teks berada dalam grid ritme 4px
  3. Keterbacaan sebagai prioritas utama — Sebelum estetika, sebelum gaya

📐 Type Scale: Fluid Modular Scale

Kita menggunakan modular scale 1.25 (major third) yang fluid — menyesuaikan antara viewport.

/* Font size scale — fluid, minor third (1.125) hingga major third (1.25) */
--fs-xs:    clamp(0.69rem, 0.69rem + 0.01vw, 0.75rem);    /* 11–12px */
--fs-sm:    clamp(0.81rem, 0.81rem + 0.02vw, 0.88rem);    /* 13–14px */
--fs-base:  clamp(0.94rem, 0.94rem + 0.03vw, 1.00rem);    /* 15–16px ★ */
--fs-md:    clamp(1.06rem, 1.06rem + 0.04vw, 1.13rem);    /* 17–18px */
--fs-lg:    clamp(1.19rem, 1.19rem + 0.06vw, 1.25rem);    /* 19–20px */
--fs-xl:    clamp(1.31rem, 1.31rem + 0.08vw, 1.50rem);    /* 21–24px */
--fs-2xl:   clamp(1.50rem, 1.50rem + 0.12vw, 1.88rem);    /* 24–30px */
--fs-3xl:   clamp(1.69rem, 1.69rem + 0.18vw, 2.25rem);    /* 27–36px */
--fs-4xl:   clamp(1.88rem, 1.88rem + 0.26vw, 2.81rem);    /* 30–45px */
--fs-5xl:   clamp(2.25rem, 2.25rem + 0.38vw, 3.50rem);    /* 36–56px */
--fs-6xl:   clamp(2.50rem, 2.50rem + 0.50vw, 4.00rem);    /* 40–64px */

Mengapa clamp()? Font size yang terlalu besar di mobile dan terlalu kecil di desktop adalah masalah UX klasik. Dengan clamp(), kita dapatkan ukuran yang optimal di setiap viewport tanpa media query.

Line Height

--lh-tight:   1.15;   /* Heading besar, display text */
--lh-normal:  1.50;   /* Body text, paragraphs */
--lh-relaxed: 1.65;   /* Long-form reading */
--lh-compact: 1.25;   /* UI labels, badges, small text */

Font Weight Tokens

--fw-light:      300;
--fw-regular:    400;
--fw-medium:     500;
--fw-semibold:   600;
--fw-bold:       700;
--fw-extrabold:  800;

🔤 Font Family

Primary: "Outfit" — Modern Geometric Sans

--ff-sans:    'Outfit', system-ui, -apple-system, sans-serif;
--ff-display: 'Outfit', system-ui, -apple-system, sans-serif;

Mengapa Outfit menggantikan Poppins?

  • Geometric precision — Bentuk huruf yang bersih, cocok untuk UI modern
  • Low x-height — Memberi kesan elegan dan lega
  • Variable font support — Satu file untuk semua weight, performa lebih baik
  • Open-source — SIL Open Font License

Monospace: "JetBrains Mono"

--ff-mono:    'JetBrains Mono', 'Fira Code', 'Cascadia Code', monospace;

Untuk: ID, timestamp, kode, data teknis, metrik.

🎭 Rich Text & Emphatic Styles

/* Links */
a, .link {
  color: var(--clr-primary-400);
  text-decoration: none;
  transition: opacity var(--dur-fast) var(--ease-out);

  text-underline-offset: 2px;
}

/* Code inline */
code, .code-inline {
  font-family: var(--ff-mono);
  font-size: 0.9em;
  padding: 0.125em 0.375em;
  background: var(--clr-surface-sunken);

  overflow: hidden;
  text-overflow: ellipsis;
  white-space: nowrap;

  -webkit-line-clamp: 2;
  -webkit-box-orient: vertical;
  overflow: hidden;
}

.text-clamp-3 {
  display: -webkit-box;
  -webkit-line-clamp: 3;
  -webkit-box-orient: vertical;
  overflow: hidden;

📏 Vertical Rhythm

Menggunakan sistem baseline 4px (bukan 8px default) untuk tipografi:

:root {
  --baseline: 4px;
}

/* Heading margin */
.h1 { margin-bottom: calc(var(--baseline) * 4); }  /* 16px */
.h2 { margin-bottom: calc(var(--baseline) * 3); }  /* 12px */
.h3 { margin-bottom: calc(var(--baseline) * 3); }  /* 12px */
.h4 { margin-bottom: calc(var(--baseline) * 2); }  /* 8px */

/* Paragraph spacing */
p, .body {
  margin-bottom: calc(var(--baseline) * 4);  /* 16px */
}

p + p {
  margin-top: calc(var(--baseline) * 2);  /* 8px — reduced between consecutive paragraphs */
}

⚠️ Anti-Patterns Tipografi

❌ Ukuran absolut tanpa fluid

/* ❌ JANGAN — title 32px di mobile terlalu besar */
.page-title { font-size: 32px; }

/* ✅ clamp menyesuaikan viewport */
.page-title { font-size: var(--fs-4xl); }

❌ Line height terlalu kecil untuk body text

/* ❌ JANGAN — crowded, sulit dibaca */
.body-text { font-size: 16px; line-height: 1.2; }

/* ✅ Line height yang cukup untuk readability */
.body-text { font-size: var(--fs-base); line-height: var(--lh-normal); }

❌ Terlalu banyak type scale

/* ❌ JANGAN — 29px, 28px, 27px, 26px adalah noise */
.custom-1 { font-size: 29px; }
.custom-2 { font-size: 28px; }

/* ✅ Gunakan scale yang terdefinisi */
.custom { font-size: var(--fs-4xl); }
