DIV CSS 佈局教程網

bootstrap為我們定義了簡潔易用的樣式，我們只需要很少的樣式指定，就可以完成簡約優雅的頁面展示。
本篇主要介紹以下幾個基本控件：
1. table
2. form
3. button

1. 表格（table）依舊使用<table><thead><tbody><tr><th><td>來表現表格。有如下的類來控制table的屬性， table樣式默認會占滿父容器

 <div class="container">
    <div class="row">
      <div class="col-md-8 col-md-offset-2">
        <table class="table table-bordered table-striped table-hover">
      <tr>
        <th>標題一</th>
        <th>標題二</th>
        <th>標題三</th>
      </tr>
      <tr>
        <td>1</td>
        <td>2</td>
        <td>3</td>
      </tr>
      <tr>
        <td>4</td>
        <td>5</td>
        <td>6</td>
      </tr>
    </table>
      </div>
    </div>
  </div>

將任何.table包裹在.table-responsive中即可創建響應式表格，其會在小屏幕設備上（小於768px）水平滾動。當屏幕大768px寬度時，水平滾動條消失。

2. 表單form, 有如個幾種樣式定義

lable與控件要用form-group類型的div包起來，默認表單如下

 <div class="container">
    <form>
      <div class="form-group">
        <label for="exampleInputEmail1">Email address</label>
        <input type="email" class="form-control" id="exampleInputEmail1"
          placeholder="Enter email">
      </div>
      <div class="form-group">
        <label for="exampleInputPassword1">Password</label>
        <input type="password" class="form-control"
          id="exampleInputPassword1" placeholder="Password">
      </div>
      <div class="checkbox">
        <label> <input type="checkbox"> Check me out
        </label>
      </div>
      <button type="submit" class="btn btn-default">Submit</button>
    </form>
  </div>

內聯表單，為label指定sr-only類別，可隱藏掉標簽，但必須 不可省略lable.

  <div class="container">
    <form class="form-inline">
      <div class="form-group">
        <label for="exampleInputEmail1" class="sr-only">Email address</label>
        <input type="email" class="form-control" id="exampleInputEmail1"
          placeholder="Enter email">
      </div>
      <div class="form-group">
        <label for="exampleInputPassword1">Password</label>
        <input type="password" class="form-control"
          id="exampleInputPassword1" placeholder="Password">
      </div>
      <div class="checkbox">
        <label> <input type="checkbox"> Check me out
        </label>
      </div>
      <button type="submit" class="btn btn-default">Submit</button>
    </form>
  </div>

水平類型的表單，要為lable與標簽組指定長度， 采用柵格系統的布局方式。 label右對齊，標簽組左對齊。  

 <div class="container">
    <form class="form-horizontal">
      <div class="form-group">
          <label for="exampleInputEmail1" class="col-md-2 control-label">Email
            address</label>
        <div class="col-md-8">
          <input type="email" class="form-control" id="exampleInputEmail1"
            placeholder="Enter email">
        </div>
      </div>
      <div class="form-group" >
          <label for="exampleInputPassword1" class="col-md-2 control-label">Password</label>
        <div class="col-md-8">
          <input type="password" class="form-control"
            id="exampleInputPassword1" placeholder="Password">
        </div>
      </div>
      <div class="checkbox col-md-offset-2">
        <label> <input type="checkbox"> Check me out
        </label>
      </div>
      <button type="submit" class="btn btn-default col-md-offset-2">Submit</button>
    </form>
  </div>

form表單驗證，bootstrap3支持表單的自定義驗證。 加入req    uired表示表單必填，node.setCustomValidity可以設置表單的自定義驗證

<div class="container">
    <form class="form-horizontal">
      <div class="form-group">
        <label for="exampleInputEmail1" class="col-md-2 control-label">Email
          address</label>
        <div class="col-md-8">
          <input type="email" class="form-control" id="exampleInputEmail1"
            placeholder="Enter email" required>
        </div>
      </div>
      <div class="form-group">
        <label for="password1" class="col-md-2 control-label">Password</label>
        <div class="col-md-8">
          <input type="password" class="form-control"
            id="password1" placeholder="Password" required onchange="checkPassword()">
        </div>
      </div>
<div class="form-group">
        <label for="password2" class="col-md-2 control-label" onchange="checkPassword()"> Password2</label>
        <div class="col-md-8">
          <input type="password" class="form-control"
            id="password2" placeholder="Password2" required>
        </div>
      </div>
      <div class="checkbox col-md-offset-2">
        <label> <input type="checkbox"> Check me out
        </label>
      </div>
      <button type="submit" class="btn btn-default col-md-offset-2">Submit</button>
    </form>
  </div>
  
  <script>
    function checkPassword() {
      var pwd1 = $("#password1").val();
      var pwd2 = $("#password2").val();
      if (pwd1 != pwd2) {
        document.getElementById("password1").setCustomValidity("兩次輸入的密碼不一致");
      } else {
        document.getElementById("password1").setCustomValidity("");
      }
      
    }
  </script>

3. button的樣式

使用.btn-lg、.btn-sm、.btn-xs可以獲得不同尺寸的按鈕， 給按鈕添加.btn-block可以使其充滿父節點100%的寬度，而且按鈕也變為了塊級（block）元素， <a>、<button>或<input>元素添加按鈕class。 

  <div class="container">
    <button type="button" class="btn btn-default btn-block">Default</button>
    <button type="button" class="btn btn-primary btn-block">Primary</button>
    <button type="button" class="btn btn-success">Success</button>
    <button type="button" class="btn btn-info">Info</button>
    <button type="button" class="btn btn-warning">Warning</button>
    <button type="button" class="btn btn-danger">Danger</button>
    <button type="button" class="btn btn-link">鏈接</button>
    <a class="btn btn-default" href="#" role="button">Link</a>
    <button class="btn btn-default" type="submit">Button</button>
    <input class="btn btn-default" type="button" value="Input">
    <input class="btn btn-default" type="submit" value="Submit">
  </div>
