Bootstrap 布局
在本教程中,您將學習如何使用 Bootstrap 工具包來創(chuàng)建固定布局和流動布局。教程是基于 Bootstrap 版本 2.0。
在版本 2.0 中,Bootstrap 為手機、平板電腦、筆記本、小型臺式機、大型寬屏臺式機等添加了響應特性。
可以通過向頁面添加 bootstrap-responsive.css 文件(位于 docs\assets\css 下)來讓布局具有響應性。
如果您想要創(chuàng)建基于固定像素數(shù)的網頁或 app,請看這部分的教程。
用法
<body>
<div class="container">
...
</div>
</body>
解釋
bootstrap.css(位于 bootstrap 的主文件夾的 docs\assets\css 下)的第 261 到 273 行,為創(chuàng)建主容器渲染樣式,從而創(chuàng)建一個固定布局。固定布局的目的是為網頁或 app 創(chuàng)建一個 940 像素(默認)寬的布局。
下面的代碼創(chuàng)建一個網頁固定布局。為了定制,除了默認樣式,還需創(chuàng)建一個新的 css 文件 example-fixed-layout.css,與 bootstrap.css 位于同一個文件夾下。
