# experimenta Design System

**Version:** 1.0
**Letzte Aktualisierung:** 2025-10-30
**Font:** Roboto (Open Source Alternative zu DIN OT)

Dieses Design System definiert die visuelle Identität und Komponenten-Bibliothek für **my.experimenta.science**. Es basiert auf dem Corporate Design der experimenta Science Center Website und den bereitgestellten Design-Vorlagen.

---

## ⚠️ Wichtiger Hinweis zu Schriftarten

**Wir verwenden Roboto statt der DIN OT Hausschrift.**

**Gründe:**
- **Open Source:** Roboto ist kostenlos und frei verfügbar
- **Web-Performance:** Optimiert für digitale Anwendungen
- **Ähnliche Optik:** Moderne, klare Sans-Serif ähnlich zu DIN OT
- **DSGVO-konform:** Lokales Hosting ohne externe CDN-Abhängigkeit (Google Fonts)

**Font-Hosting:**
- Die Roboto-Schrift wird lokal aus `/public/fonts/roboto/` geladen
- @font-face Deklarationen befinden sich in `assets/css/tailwind.css`
- Benötigte Weights: 300 (Light), 400 (Regular), 500 (Medium), 700 (Bold)
- Format: WOFF2 (beste Kompression, moderne Browser-Unterstützung)

## Typografie

### Font-Family

**Roboto** (Open Source, ähnlich zu DIN OT, lokal gehostet)

```css
font-family: 'Roboto', sans-serif;
```

**Lokales Hosting:**

Die Roboto-Schrift wird lokal aus `/public/fonts/roboto/` geladen:

```bash
public/fonts/roboto/
├── Roboto-VariableFont-latin.woff2  # Variable Font (Weight 100-900)
└── roboto.css                        # @font-face Deklarationen
```

**Variable Font:** Wir nutzen eine einzige Variable Font Datei, die alle Weights von 100-900 abdeckt. Das bedeutet bessere Performance (nur eine Datei statt 4 separate Dateien) und nahtlose Übergänge zwischen Font-Weights.

**@font-face Deklarationen:** Siehe `assets/css/tailwind.css` (Zeile 15-40)

**Download:** Die Datei wurde bereits heruntergeladen. Falls neu benötigt: [Google Fonts - Roboto](https://fonts.google.com/specimen/Roboto) → Download → WOFF2 Format → Variable Font auswählen

**Gewichte:**

- `300` - Light (Headlines)
- `400` - Regular (Body Text)
- `500` - Medium (Buttons, Labels)
- `700` - Bold (Footer Links, Strong Text)

### Font-Scale (Desktop)

| Element        | Size | Weight | Line Height | Letter Spacing |
| -------------- | ---- | ------ | ----------- | -------------- |
| **H1**         | 36px | 300    | 1.2         | -1px           |

## Komponenten

### 1. Buttons

#### Primary Button

**Style:**

```css
background: #e6007e;
background-image: linear-gradient(to left, #e6007e, #e6007e, #e40521, #e6007e);
background-size: 300%;
color: #ffffff;
padding: 10px 30px;
border-radius: 25px;
font-size: 18px;
font-weight: 500;
transition:
  background-position 1s,
  all 0.3s ease;

/* Hover */
background-position: 100%;
```

**Tailwind:**

```html
<button class="btn-primary">Zur experimenta Startseite</button>
```

**CSS Klasse (Tailwind Config):**

```css
.btn-primary {
  @apply bg-gradient-to-l from-primary via-red to-primary;
  @apply bg-[length:300%] bg-left;
  @apply text-white px-8 py-2.5 rounded-full;
  @apply text-lg font-medium;
  @apply transition-all duration-300;
  @apply hover:bg-right;
}
```

#### Secondary Button

**Style:**

```css
background: transparent;
border: 2px solid rgba(255, 255, 255, 0.3);
color: #ffffff;
padding: 10px 30px;
border-radius: 25px;
font-size: 18px;
font-weight: 500;
transition: all 0.3s ease;

/* Hover */
background: #ffffff;
color: #2e1065; /* Dark purple text on white */
border-color: #ffffff;
```

**Tailwind:**

```html
<button class="btn-secondary">Abbrechen</button>
```

**CSS Klasse (Tailwind Config):**

```css
.btn-secondary {
  @apply inline-block relative;
  @apply px-[30px] py-[10px];
  @apply text-lg font-medium text-white;
  @apply rounded-[25px];
  @apply bg-transparent border-2 border-white/30;
  @apply transition-all duration-300;
  @apply hover:bg-white hover:text-purple-darkest hover:border-white;
}
```

#### Destructive Button

**Verwendung:** Gefährliche/irreversible Aktionen (z.B. "Konto löschen", "Bestellung stornieren", "Aus Warenkorb entfernen")

**Style:**

```css
background: #ea5b0c;
background-image: linear-gradient(to left, #ea5b0c, #ea5b0c, #c7490a, #ea5b0c);
background-size: 300%;
color: #ffffff;
padding: 10px 30px;
border-radius: 25px;
font-size: 18px;
font-weight: 500;
transition: background-position 1s, all 0.3s ease;

/* Hover */
background-position: 100%;
```

**Tailwind:**

```html
<button class="btn-destructive">Aus Warenkorb entfernen</button>
```

**CSS Klasse (Tailwind Config):**

```css
.btn-destructive {
  @apply inline-block relative;
  @apply px-[30px] py-[10px];
  @apply text-lg font-medium text-white;
  @apply rounded-[25px];
  @apply cursor-pointer;
  @apply border-0 outline-0;
  @apply no-underline;
  background: #ea5b0c;
  background-image: linear-gradient(to left, #ea5b0c, #ea5b0c, #c7490a, #ea5b0c);
  background-size: 300%;
  background-position: 0%;
  line-height: 1.7em;
  transition: background-position 1s, all 0.3s ease;
}

.btn-destructive:hover {
  background-position: 100%;
}
```

**Design-Rationale:**
- **EXP Signalorange** (#ea5b0c) aus dem offiziellen experimenta Styleguide
- Signalisiert "Vorsicht" und "Gefahr" (stärker als gelbes Orange, weniger aggressiv als reines Rot)
- Konsistentes Animations-Pattern wie Primary Button (1s Gradient-Shift)
- Klar unterscheidbar vom Primary Button (Pink/Rot vs. Signal-Orange)
- Offizielle CI-Farbe für Warnungen und destruktive Aktionen

#### Button Sizes

```html
<!-- Large (default) -->
<button class="btn-primary text-lg px-8 py-2.5">
  <!-- Medium -->
  <button class="btn-primary text-base px-6 py-2">
    <!-- Small (mobile) -->
    <button class="btn-primary text-base px-6 py-2 md:px-8 md:py-2.5"></button>
  </button>
</button>
```
