01 · Context & Problem

Real estate sites are slow, generic, and lose leads at the first scroll.

地產網站速度慢、模版化,第一屏就流失潛在客戶。

Most real estate agents use templated platforms (Squarespace, Wix, board-provided portals) that load heavy JavaScript frameworks, prioritize MLS feed over conversion, and have zero personality. The result: sites that feel like property databases rather than a trusted advisor's presence.

大多數地產經紀人使用模板平台(Squarespace、Wix 或協會提供的入口),載入重型 JavaScript 框架,以 MLS 信息為重心而非轉化,且毫無個人風格。結果:網站感覺像物業數據庫,而非可信賴顧問的存在。

The Brief
設計要求

Build a conversion-first landing page that: (1) loads hero content instantly without waiting for external JS, (2) captures seller leads via a multi-step valuation tool, (3) showcases neighbourhoods to establish local authority, and (4) communicates trust through social proof — all without any framework or library.

建立一個以轉化為首要目標的落地頁:(1) 無需等待外部 JS 即可即時載入 Hero 內容;(2) 透過多步驟估價工具捕捉賣家潛在客戶;(3) 展示社區以建立本地專業形象;(4) 透過社會認證傳達信任——全部無需任何框架或庫。

02 · Tech Deep Dive

Zero dependencies. Maximum performance.

零依賴。最大效能。

The site ships no npm packages, no framework, no runtime. Every interaction — the scroll animations, the carousel, the multi-step form, the counter animations — is vanilla JS. This keeps Time-to-Interactive under 1 second and eliminates an entire class of dependency vulnerabilities.

網站不包含 npm 包、框架或運行時。所有互動——滾動動畫、輪播、多步驟表單、計數器動畫——均為原生 JS。這使互動時間保持在 1 秒以內,並消除了整類依賴漏洞。

// Critical CSS Inline
// 內聯關鍵 CSS

Nav + hero styles are inlined in <head>. The full stylesheet loads async via preload. First Contentful Paint happens before any network round-trip.

Nav + Hero 樣式內聯於 <head>。完整樣式表通過 preload 異步加載。首次內容繪製在任何網路往返之前完成。

// requestIdleCallback
// 空閒時初始化

Non-critical modules (valuation form, communities, testimonials) initialize inside requestIdleCallback — the browser handles them when the main thread is free, not during page load.

非關鍵模塊(估價表單、社區、推薦信)在 requestIdleCallback 內初始化——瀏覽器在主線程空閒時處理,而非頁面加載期間。

// IntersectionObserver
// 滾動觸發動畫

All scroll-triggered reveal animations use IntersectionObserver — no scroll event listeners, no layout thrashing. Each element observes itself and unobserves after animating.

所有滾動觸發的揭示動畫使用 IntersectionObserver——無滾動事件監聽器,無佈局抖動。每個元素自我觀察,動畫後取消觀察。

// JSON-LD Schema
// 結構化資料 SEO

RealEstateAgent schema with aggregateRating and review array. Enables Google rich results (star ratings in SERPs) without any plugin.

RealEstateAgent schema 含 aggregateRatingreview 陣列。無需任何插件即可在 Google 搜索結果中顯示星級評分。

// WebP + <picture>
// 響應式圖片

Every image uses <picture> with WebP <source> and JPEG fallback. srcset and sizes ensure the browser downloads exactly the right resolution for each viewport.

每張圖片使用帶 WebP <source> 和 JPEG 備用的 <picture>srcsetsizes 確保瀏覽器為每個視口下載恰好合適的分辨率。

// Multi-Step Valuation Form
// 多步驟估價表單

Address → Contact → Loading sequence → Result. Inline field validation on blur/input. A fake progress bar with rotating AI-copy messages sells the "analysis" UX during the 4-second wait.

地址 → 聯絡資料 → 加載序列 → 結果。失焦/輸入時的內聯字段驗證。假進度條配合輪換 AI 文案訊息,在 4 秒等待中銷售「分析」使用體驗。

Hardest Part — Hero image loading without layout shift
最難的部分——Hero 圖片加載而不引起佈局偏移

The Ken Burns zoom animation (transform: scale(1.04)scale(1) over 12 seconds) had to start before the hero image fully loaded, or the first frame would show a jerky jump. The fix: set explicit width and height attributes on the <img> to reserve the layout space, use fetchpriority="high" and a <link rel="preload"> in <head> so the image is fetched as the highest priority resource, and start the CSS animation unconditionally — by the time it matters visually, the image is already loaded.

Ken Burns 縮放動畫(12 秒內 transform: scale(1.04)scale(1))必須在 Hero 圖片完全加載之前開始,否則第一幀會出現跳躍。解決方案:在 <img> 上設置明確的 widthheight 屬性以預留佈局空間,在 <head> 中使用 fetchpriority="high"<link rel="preload"> 使圖片以最高優先級獲取,並無條件啟動 CSS 動畫——在視覺上重要之前,圖片已經加載完成。
