bootstrap有什麼佈局方式？
bootstrap有固定佈局和流動佈局：固定佈局即創建基於固定像素數的網頁或app；流動佈局即創建一個非固定的佈局，即基於百分比的佈局，以便讓佈局更靈活。

解釋
bootstrap.css（位於bootstrap 的主資料夾的docs\assets\css 下）的第261 到273行，為建立主容器渲染樣式，從而建立一個固定佈局。固定佈局的目的是為網頁或 app 創建一個 940 像素（預設）寬的佈局。
Bootstrap 固定佈局的實例
下面的程式碼建立一個網頁固定佈局。為了定制，除了預設樣式，還需建立一個新的 css 檔案 example-fixed-layout.css，與 bootstrap.css 位於同一個資料夾下。

padding-top: 60px;
padding-bottom: 40px;

.nav li {
