bootStrap

BootaStrap到底是个什么玩意？

话不多说官网献上：bootStrap官网

bootStrap：一种前端框架（将方法、属性等进行封装，真正走上了复制、粘贴的阳光大道）

1、开始之前的准备

  1、引入bootStrap.css，敢问不引入怎么用？！
  2、引入jQuery，因为bootStrap的js都依赖于jQuery。
  3、引入bootStrap自己的js。
 （4、如果需要往往还需要引入UI提供的字体图标）

2、栅栏

3、Progress

  <div class="container">
<div class="row">
    <div class="progress">
        <div class="progress-bar progress-bar-success" role="progressbar" aria-valuenow="40" aria-valuemin="0"
            aria-valuemax="100" style=" 40%">
            <span class="sr-only">40% Complete (success)</span>
        </div>
    </div>
    <div class="progress">
        <div class="progress-bar progress-bar-info" role="progressbar" aria-valuenow="20" aria-valuemin="0"
            aria-valuemax="100" style=" 20%">
            <span class="sr-only">20% Complete</span>
        </div>
    </div>
    <div class="progress">
        <div class="progress-bar progress-bar-warning" role="progressbar" aria-valuenow="60" aria-valuemin="0"
            aria-valuemax="100" style=" 60%">
            <span class="sr-only">60% Complete (warning)</span>
        </div>
    </div>
    <div class="progress">
        <div class="progress-bar progress-bar-danger" role="progressbar" aria-valuenow="80" aria-valuemin="0"
            aria-valuemax="100" style=" 80%">
            <span class="sr-only">80% Complete (danger)</span>
        </div>
    </div>
</div>

别瞎想，代码直接复制粘贴

4、轮播图大将！

  `<div class="container">
<div class="row">
    <div id="carousel-example-generic" class="carousel slide" data-ride="carousel">
        <!-- Indicators -->
        <ol class="carousel-indicators">
            <li data-target="#carousel-example-generic" data-slide-to="0" class="active"></li>
            <li data-target="#carousel-example-generic" data-slide-to="1"></li>
            <li data-target="#carousel-example-generic" data-slide-to="2"></li>
        </ol>
        <!-- Wrapper for slides -->
        <div class="carousel-inner" role="listbox">
            <div class="item active">
                <img src="../day02/weijinsuo/images/slide_01_640x340.jpg" alt="...">
                <div class="carousel-caption">
                </div>
            </div>
            <div class="item">
                <img src="../day02/weijinsuo/images/slide_03_2000x410.jpg" alt="...">
                <div class="carousel-caption">
                </div>
            </div>
            <div class="item">
                <img src="../day02/weijinsuo/images/slide_04_2000x410.jpg" alt="...">
                <div class="carousel-caption">
                </div>
            </div>
        </div>
        <!-- Controls -->
        <a class="left carousel-control" href="#carousel-example-generic" role="button" data-slide="prev">
            <span class="glyphicon glyphicon-chevron-left" aria-hidden="true"></span>
            <span class="sr-only">Previous</span>
        </a>
        <a class="right carousel-control" href="#carousel-example-generic" role="button" data-slide="next">
            <span class="glyphicon glyphicon-chevron-right" aria-hidden="true"></span>
            <span class="sr-only">Next</span>
        </a>
    </div>
</div>

轮播图 几秒解决，如果轮播数量不够可以添加，轮播速度慢可以加速！

结尾！！！

  几乎每一个功能实现都需要container和row进行包裹，勿忘！
  `<div class="container">
      <div class="row"></div>
   </div>`
