<h3><strong>1.基础表单</strong></h3>
在Bootstrap框架中，通过定制了一个类名`form-control`，也就是说，如果这几个元素使用了类名“form-control”，将会实现一些设计上的定制效果。
1、宽度变成了100%
2、设置了一个浅灰色（#ccc）的边框
3、具有4px的圆角
4、设置阴影效果，并且元素得到焦点之时，阴影和边框效果会有所变化
5、设置了placeholder的颜色为#999
<form role="form">
<div class="form-group">
<label for="exampleInputEmail1">邮箱：</label>
<input type="email" class="form-control" id="exampleInputEmail1" placeholder="请输入您的邮箱地址">
</div>
<div class="form-group">
<label for="exampleInputPassword1">密码</label>
<input type="password" class="form-control" id="exampleInputPassword1" placeholder="请输入您的邮箱密码">
</div>
<div class="checkbox">
<label>
<input type="checkbox"> 记住密码
</label>
</div>
<button type="submit" class="btn btn-default">进入邮箱</button>
</form> <h3><strong>2.水平表单 必须满足1、在form元素是使用类名“form-horizontal”。2、配合Bootstrap框架的网格系统。</strong></h3>
<form class="form-horizontal" role="form">
<div class="form-group">
<label for="inputEmail3" class="col-sm-2 control-label">邮箱</label>
<div class="col-sm-10">

</form> <h3><strong>3.内联表单 sr-only 隐藏了lable 为了屏幕阅读器识别输入控件</strong></h3>
<form class="form-inline" role="form">
<div class="form-group">
<!--<label class="sr-only" for="exampleInputEmail2">邮箱</label>-->
<input type="email" class="form-control" id="exampleInputEmail2" placeholder="请输入你的邮箱地址">

<form role="form">
<div class="form-group">
<input type="email" class="form-control" placeholder="Enter email">
</div>
</form> <h3><strong>5.表单控件——下拉选择框select元素 多行选择设置multiple属性的值为multiple</strong></h3>

<option>5</option>
</select>
</div>
</form> <h3><strong>6.表单控件(文本域textarea) 如果textarea元素中添加了类名“form-control”类名，则无需设置cols属性。因为Bootstrap框架中的“form-control”样式的表单控件宽度为100%或auto</strong></h3>

在Bootstrap框架中，要禁用按钮有两种实现方式：
方法1：在标签中添加disabled属性
方法2：在元素标签中添加类名“disabled”
两者的主要区别是：
.disabled”样式不会禁止按钮的默认行为，比如说提交和重置行为等。如果想要让这样的禁用按钮也能禁止按钮的默认行为，则需要通过JavaScript这样的语言来处理。
对于 a 标签也存在类似问题，如果通过类名“.disable”来禁用按钮，其链接行为是无法禁止。而在元素标签中添加“disabled”属性的方法是可以禁止元素的默认行为的。
<button class="btn btn-primary btn-lg btn-block" type="button" disabled="disabled">通过disabled属性禁用按钮</button>
<button class="btn btn-primary btn-block disabled" type="button">通过添加类名disabled禁用按钮</button>
<button class="btn btn-primary btn-sm btn-block" type="button">未禁用的按钮</button> <h3><strong>17.图像</strong></h3>
