我在我的ASP.NET應用程序中使用Bootstrap-Twitter樣式，並使用Master-Content架構（代碼如下）。在第一次加載一切正常，並排兩個span6 div，頂級菜單正常..我檢查了@media風格，這對兩個div都可以。當任何更新面板執行部分渲染時（單擊左側更新面板中的樹），所有內容都會更改。主要和我認爲關鍵的問題是，現在@media被改變了（現在是@media（max-width：767px），而更新之前是@media（min-width：1200px））。當您在平板電腦或某些小分辨率中打開時，這種更改顯示頁面的寬屏幕顯示器，這隻發生在更新面板部分渲染上。有沒有人有這種類型的錯誤的經驗？在ASP.NET中使用UpdatePanel部分呈現的Bootstrap css
