bootstrap为我们定义了简洁易用的样式，我们只需要很少的样式指定，就可以完成简约优雅的页面展示。
本篇主要介绍以下几个基本控件：
1. table
2. form
3. button
1. 表格（table）依旧使用<table><thead><tbody><tr><th><td>来表现表格。有如下的类来控制table的属性， table样式默认会占满父容器
<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>标题一</th> <th>标题二</th> <th>标题三</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>
将任何.table包裹在.table-responsive中即可创建响应式表格，其会在小屏幕设备上（小于768px）水平滚动。当屏幕大768px宽度时，水平滚动条消失。
2. 表单form, 有如个几种样式定义
lable与控件要用form-group类型的div包起来，默认表单如下
<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>
内联表单，为label指定sr-only类别，可隐藏掉标签，但必须 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>
水平类型的表单，要为lable与标签组指定长度， 采用栅格系统的布局方式。 label右对齐，标签组左对齐。
<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表单验证，bootstrap3支持表单的自定义验证。 加入req uired表示表单必填，node.setCustomValidity可以设置表单的自定义验证
<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("两次输入的密码不一致");
} else {
document.getElementById("password1").setCustomValidity("");
}
}
</script>
3. button的样式
使用.btn-lg、.btn-sm、.btn-xs可以获得不同尺寸的按钮， 给按钮添加.btn-block可以使其充满父节点100%的宽度，而且按钮也变为了块级（block）元素， <a>、<button>或<input>元素添加按钮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">链接</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>
