讓相簿圖片在網頁上呈現「瀑布流」+「自適應」版型﹍jQuery 畫廊外掛

這篇是「jQuery 相簿畫廊外掛 nanogallery2」系列文的第三篇，前兩篇分別介紹了：

• Grid 網格式排版
• Mosaic 拼貼式排版

接下來介紹剩餘的兩種版面效果，但是標題 "自適應版型"中文的字面跟英文原用語 "justified"比較難做連結，主要是網路上找不到相關的用詞，比較正確的描述是 "左右對齊"版型。

以文字來說 "左右對齊"很好理解，但圖片 "左右對齊"究竟是什麼狀況我想很難想像得出來，或許 "自適應"還比較能理解，不過沒關係後面會圖解說明。

一、版型效果

1. Justified 對齊式(自適應)



如上圖，雖然每張圖片大小比例不一、參差不齊，但很神奇的是，每一行的左右邊界圖片都能剛好切齊，因此整個版面看起來並不突兀，如同文字排版 justified 的左右對齊一般。

那麼作為畫廊(gallery)展示效果，Justified 對齊式是不錯的選擇，不必把每張圖片的尺寸比例調整一致，又能維持版面美觀。


2. Cascading 瀑布式



這個畫廊展示效果跟網頁版型中所謂的「瀑布流」很像，一方面圖片還沒全部顯示完之前，會以「無限捲動」的方式載入圖片，就像滑 FB 一樣，只要後面還有資訊就會不斷地載入。

一方面圖片往下產生的效果也很像瀑布流，左右根據圖片不同的比例，各自冒出來、下落的距離也不同。

如上圖，最終圖片完全載入後，底部是長短不一的，可能沒有那麼整齊畫一，但也是有人喜愛這種不落俗套的美感。


3. 其他相關外掛

我個人比較喜歡「nanogallery2」這個外掛，因為含括了所有常見排版方式。如果只需要特定版型的畫廊外掛，也是可考慮使用特定的外掛，以下推薦的兩個都滿不錯的：

• 對齊式：「Justified Gallery」
• 瀑布式：「Masonry」

二、Justifed 對齊式版型

官網提供了範例效果及程式碼，操作流程如下：

• 進入網頁「nanogallery2 demonstrations」
• 1. Select a demo family → 選擇「Gallery layouts」
• 2. Select demonstration → 按下「Justified gallery」

提供範例程式碼如下：
