css/js 加載順序

Firefox and Opera are the only browsers capable of loading  scripts in parallel while preserving execution order. In all other browsers, scripts must be loaded sequentially.

//只有Firefox和opera支持並行加載腳本，並保持執行順序。其餘遊覽器必須按順序進行加載。

All browsers respect CSS specificity based on the order of the link elements in the DOM, regardless of the order in which the stylesheets are actually downloaded.

//全部遊覽器根據link在樣式表的順序進行渲染，而非根據最終下載時間。
