1.瞭解Bootstrap:

簡潔，直觀，強悍的前端開發框架，讓web開發更迅速，簡單。

2.優點：

快速，簡單，靈活的柵格系統，小而強大，響應式佈局，跨平臺等。

3.下載

登陸BootStrap的官方網站下載：  http://getbootstrap.com/  。


下面使用Bootstrap官方提供的模板來設計一個響應式佈局。

（1）從下載的BootStrap中找出bootstrap.min.css檔案複製到專案中。

（2）新建一個style.css檔案，實現程式碼如下：

.row{

    margin-bottom: 20px;


}

.row .row{

    margin-top: 10px;
    margin-bottom: 0px;

}

[class*="col-"]{
    padding-top: 15px;
    padding-bottom: 15px;
    background-color: #eee;
    background-color: rgba(86,61,124,.15);
    border: 1px solid #dddddd;
    border: 1px solid rgba(86, 61, 214,.2);

}



（3）新建一個HTML檔案，實現程式碼如下，其中的程式碼都是Bootstrap官網提供的示例程式碼，可以用起來非常的方便。

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title></title>

    <link href="bootstrap.min.css" type="text/css" rel="stylesheet">
    <link href="style.css" type="text/css" rel="stylesheet">

</head>
<body>

<div class="container">

<!--導航欄-->
    <nav class="navbar navbar-default">
        <div class="container-fluid">
            <!-- Brand and toggle get grouped for better mobile display -->
            <div class="navbar-header">
                <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1" aria-expanded="false">
                    <span class="sr-only">Toggle navigation</span>
                    <span class="icon-bar"></span>
                    <span class="icon-bar"></span>
                    <span class="icon-bar"></span>
                </button>
                <a class="navbar-brand" href="#">Brand</a>
            </div>

            <!-- Collect the nav links, forms, and other content for toggling -->
            <div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
                <ul class="nav navbar-nav">
