Pure.CSS - 響應式設計

上一個
下一個

Pure.CSS 有多個特殊類，用於建立響應式設計。

序號 類名及說明
1

.pure-u-*

設定容器以佔用任何裝置上的所需空間。
2

.pure-u-sm-*

設定容器以佔用寬度 ≥ 568px 的裝置上所需的空間。
3

.pure-u-md-*

設定容器以佔用寬度 ≥ 768px 的裝置上所需的空間。
4

.pure-u-lg-*

設定容器以佔用寬度 ≥ 1024px 的裝置上所需的空間。

5

.pure-u-xl-*

設定容器以佔用寬度 ≥ 1280px 的裝置上所需的空間。

在以下示例中，我們要針對具有四欄的行建立一個響應式網格。這些欄應在小螢幕上堆疊，在中等大小的螢幕上應採用 50% 的寬度，在大螢幕上應採用 25% 的寬度。

透過為小螢幕新增 .pure-u-1 類，為中型螢幕新增 .pure-u-md-1-2 類，為大螢幕新增 .pure-u-lg-1-4 類的方式實現上述目的。調整頁面大小，檢視網格對螢幕大小的響應方式。
