結論
身為 Web 開發人員，我們經常遇到建立卡片元件的需要。無論是產品/項目展示、用戶個人資料還是部落格文章，卡片無處不在。
過去，創建響應式佈局是一項挑戰。由於現代 CSS 技術，特別是 CSS Flexbox 的出現，這些設計的創建變得更加簡單和直覺。
Flexbox 簡化了建立響應式佈局的過程。我們可以輕鬆地在容器中排列、對齊和間隔項目，而無需使用複雜的媒體查詢。這意味著我們可以建立完美適應不同螢幕尺寸和方向的佈局，而無需指定確切的斷點。
目標是透過使用 CSS Flexbox 來建立等高的響應式卡片，而不依賴斷點。我們將確保每張卡片無論內容長度如何都保持相同的高度，無縫適應不同的螢幕尺寸。
