|
|
|
|
**Date:** 2026-06-03
|
|
**Component:** [`frontend/src/views/LandingView.vue`](../frontend/src/views/LandingView.vue)
|
|
**Status:** ✅ Complete
|
|
|
|
---
|
|
|
|
## 🎯 Objective
|
|
|
|
Transform the landing page from a "sterile, boxy" layout into a playful, asymmetric design with:
|
|
- Fixed header (never scrolls away)
|
|
- Redesigned CSS-based logo matching reference colors
|
|
- JavaScript-powered parallax scrolling with different speeds
|
|
- Neo-glassmorphism cards with asymmetric positioning and neon effects
|
|
|
|

|
|
|
|
## 🎨 Design Analysis from Reference Image
|
|
|
|
### Color Palette Extracted:
|
|
- **Dark Navy Blue:** `#0B212F` (SERVICE text, search icon fill)
|
|
- **Bright Turquoise:** `#38bdf8` (FINDER text, primary accents, neon glow)
|
|
- **Medium Teal:** `#65A5A0` (secondary accents)
|
|
- **Deep Blue Backgrounds:** `#062535`, `#04151f` (glassmorphism layers)
|
|
|
|
### Logo Design:
|
|
- **Bottom Layer:** Compass icon in bright turquoise (`#38bdf8`)
|
|
- **Top Layer:** Search/magnifying glass in dark navy (`#0B212F`) with white stroke (`stroke-white stroke-2`)
|
|
- **Typography:** "SERVICE" in dark navy, "FINDER" in bright turquoise
|

|
|
## ✅ Implementation Details
|
|
|
|
### 1. **Fixed Top Bar (Kőbe vésett fejléc)**
|
|
|
|
```vue
|
|
<header class="fixed top-0 left-0 w-full z-50 bg-[#062535]/80 backdrop-blur-md border-b border-[#65A5A0]/20">
|
|
```
|
|
|
|
**Key Features:**
|
|
- `fixed` positioning (NOT `sticky`) - never scrolls away
|
|
- `z-50` ensures it stays above all content
|
|
- Glass effect: `bg-[#062535]/80 backdrop-blur-md`
|
|
- Subtle border: `border-[#65A5A0]/20`
|
|
|
|
---
|
|
|
|
### 2. **Redesigned CSS Logo**
|
|
|
|
**Structure:**
|
|
```vue
|
|
<div class="relative w-12 h-12">
|
|
<!-- Compass (Background) -->
|
|
<svg class="absolute inset-0 w-12 h-12 text-[#38bdf8]">
|
|
<circle cx="12" cy="12" r="10"/>
|
|
<polygon points="16.24 7.76 14.12 14.12 7.76 16.24 9.88 9.88 16.24 7.76"/>
|
|
</svg>
|
|
|
|
<!-- Search (Foreground with white stroke) -->
|
|
<svg class="absolute top-1/2 left-1/2 transform -translate-x-1/2 -translate-y-1/2
|
|
w-6 h-6 text-[#0B212F] stroke-white" stroke-width="2">
|
|
<circle cx="11" cy="11" r="7"/>
|
|
<path d="m21 21-4.35-4.35"/>
|
|
</svg>
|
|
</div>
|
|
```
|
|
|
|
**Typography:**
|
|
```vue
|
|
<span class="text-[#0B212F]">SERVICE</span>
|
|
<span class="text-[#38bdf8]">FINDER</span>
|
|
```
|
|
|
|
**Benefits:**
|
|
- Fully scalable (SVG-based)
|
|
- No image files needed
|
|
- Crisp at any resolution
|
|
- Easy to modify colors/sizes
|
|

### 3. **JS-Based Parallax Scrolling**
|
|
|
|
**Script Setup:**
|
|
```typescript
|
|
const scrollY = ref(0)
|
|
|
|
function handleScroll() {
|
|
scrollY.value = window.scrollY
|
|
}
|
|
|
|
onMounted(() => {
|
|
window.addEventListener('scroll', handleScroll)
|
|
})
|
|
|
|
onUnmounted(() => {
|
|
window.removeEventListener('scroll', handleScroll)
|
|
})
|
|
```
|
|
|
|
**Applied to Columns:**
|
|
|
|
**Left Column (Text) - Slow Downward:**
|
|
```vue
|
|
<div :style="{ transform: `translateY(${scrollY * 0.15}px)` }">
|
|
```
|
|
- Multiplier: `0.15` (moves slowly down as you scroll)
|
|
|
|
**Right Column (Cards) - Fast Upward:**
|
|
```vue
|
|
<div :style="{ transform: `translateY(${scrollY * -0.25}px)` }">
|
|
```
|
|
- Multiplier: `-0.25` (moves quickly up as you scroll, negative = opposite direction)
|
|
|
|
**Effect:** Creates depth and playfulness as content moves at different speeds.

### 4. **Playful Asymmetric Neo-Glassmorphism Cards**
|
|
|
|
#### Card Structure Pattern:
|
|
|
|
**Header Section (30% - Darker):**
|
|
```vue
|
|
<div class="bg-[#04151f]/60 backdrop-blur-md rounded-t-xl px-5 py-3
|
|
border-t border-x border-[#38bdf8]/20">
|
|
<!-- Icon + Title -->
|
|
</div>
|
|
```
|
|
|
|
**Content Section (70% - Lighter Glass):**
|
|
```vue
|
|
<div class="bg-[#062535]/40 backdrop-blur-md rounded-b-xl px-5 py-4
|
|
border-b border-x border-[#38bdf8]/20
|
|
shadow-[0_8px_30px_rgba(6,37,53,0.6)]">
|
|
<!-- Card content -->
|
|
</div>
|
|
```
|
|
|
|
---
|
|
|
|
#### Card 1: Statistics (Back, Top, Smaller)
|
|
```vue
|
|
<div class="absolute top-0 left-0 w-[280px] z-10 transform -rotate-2
|

|
|
- Z-index: `10` (behind others)
|
|
- Rotation: `-rotate-2` (tilted left)

|
|
|

|
|
|
|
#### Card 2: Gamification (Center, Featured, NEON)
|
|
```vue
|
|
<div class="absolute top-[120px] right-0 w-[320px] z-30 transform rotate-1

|
transition-transform duration-300 hover:scale-105 hover:rotate-0">
|
|
<!-- Content with NEON border -->
|
|
<div class="border border-[#38bdf8] shadow-[0_0_25px_rgba(56,189,248,0.3)]">

|
|
|
|
---
|
|
|
|
#### Card 3: Costs (Bottom, Front, Overlapping)
|
|
```vue
|
|
<div class="absolute top-[320px] left-[40px] w-[300px] z-40 transform -rotate-1
|
|
transition-transform duration-300 hover:scale-105 hover:rotate-0">
|
