bootstrap学习笔记(表单)

1.基础表单 ：对于基础表单，Bootstrap并未对其做太多的定制性效果设计，仅仅对表单内的fieldset、legend、label标签进行了定制。

fieldset {
min- 0;
padding: 0;
margin: 0;
border: 0;
}
legend {
display: block;
 100%;
padding: 0;
margin-bottom: 20px;
font-size: 21px;
line-height: inherit;
color: #333;
border: 0;
border-bottom: 1px solid #e5e5e5;
}

label {
display: inline-block;
margin-bottom: 5px;
font-weight: bold;
}
源码

2.水平表单  类名“form-horizontal”

复制代码
.form-horizontal .control-label,
.form-horizontal .radio,
.form-horizontal .checkbox,
.form-horizontal .radio-inline,
.form-horizontal .checkbox-inline {
padding-top: 7px;
margin-top: 0;
margin-bottom: 0;
}
.form-horizontal .radio,
.form-horizontal .checkbox {
min-height: 27px;
}
.form-horizontal .form-group {
margin-right: -15px;
margin-left: -15px;
}
.form-horizontal .form-control-static {
padding-top: 7px;
}
@media (min- 768px) {
.form-horizontal .control-label {
text-align: right;
  }
}
.form-horizontal .has-feedback .form-control-feedback {
top: 0;
right: 15px;
}
复制代码
源码

3.内联表单  类名“form-inline”

复制代码
<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">
</div>
<div class="form-group">
  <label class="sr-only" for="exampleInputPassword2">密码</label>
  <input type="password" class="form-control" id="exampleInputPassword2" placeholder="请输入你的邮箱密码">
</div>
<div class="checkbox">
<label>
   <input type="checkbox">记住密码
</label>
</div>
<button type="submit" class="btnbtn-default">进入邮箱</button>
</form>


<--  .sr-only:给残障人员用的 -->
<-- .sr-only {
position: absolute;
 1px;
height: 1px;
padding: 0;
margin: -1px;
overflow: hidden;
clip: rect(0, 0, 0, 0);
border: 0;
}  -->
复制代码
示例

表单控件

1.输入框input:  为了让控件在各种表单风格中样式不出错，需要添加类名“form-control”，下面各个表单控件都能加。

复制代码
<!doctype html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>表单控件——输入框input</title>
    <link rel="stylesheet" href="//netdna.bootstrapcdn.com/bootstrap/3.1.1/css/bootstrap.min.css">
</head>
<body>
<form role="form">
  <div class="form-group">
    <input type="email" class="form-control" placeholder="Enter email">
    <input type="text" class="form-control" placeholder="Enter Username">
  </div>
</form>   
</body>
</html>
复制代码
示例

type类型：text button checkbox date datetime datetime-local img file hidden month number password radio range reset search submit tel time url week hidden

2.下拉选择框select：多行选择设置multiple属性的值为multiple

<form>  
  <div class="form-group">
      <select multiple class="form-control">  //如果是下拉框就不要加multiple
          <option>踢足球</option>
          <option>游泳</option>
          <option>慢跑</option>
          <option>跳舞</option>
      </select>
  </div>
</form>
示例

3.内联表单  类名“form-inline”

复制代码
<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">
</div>
<div class="form-group">
  <label class="sr-only" for="exampleInputPassword2">密码</label>
  <input type="password" class="form-control" id="exampleInputPassword2" placeholder="请输入你的邮箱密码">
</div>
<div class="checkbox">
<label>
   <input type="checkbox">记住密码
</label>
</div>
<button type="submit" class="btnbtn-default">进入邮箱</button>
</form>


<--  .sr-only:给残障人员用的 -->
<-- .sr-only {
position: absolute;
 1px;
height: 1px;
padding: 0;
margin: -1px;
overflow: hidden;
clip: rect(0, 0, 0, 0);
border: 0;
}  -->
复制代码
示例

ea：添加了类名“form-control”类名，则无需设置cols属性。

<form role="form">
  <div class="form-group">
    <textarea class="form-control" rows="3"></textarea>
  </div>
</form>

示例

4.复选框checkbox和单选择按钮radio：水平排列加类名“checkbox-inline”||类名“radio-inline”

<form role="form">
  <div class="form-group">
    <textarea class="form-control" rows="3"></textarea>
  </div>
</form>
示例

4.复选框checkbox和单选择按钮radio：水平排列加类名“checkbox-inline”||类名“radio-inline”

<!doctype html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>表单控件——表单控件大小</title>
    <link rel="stylesheet" href="//netdna.bootstrapcdn.com/bootstrap/3.1.1/css/bootstrap.min.css">
</head>
<body>
<form role="form">
  <h3>案例1</h3>
  <div class="checkbox">

  <div class="radio">           //如果要水平class=“radio-inline”
    <label>
      <input type="radio" name="optionsRadios" id="optionsRadios1" value="love" checked>
      喜欢
    </label>
  </div>
    <div class="radio">         //如果要水平class=“radio-inline”
    <label>
      <input type="radio" name="optionsRadios" id="optionsRadios2" value="hate">
      不喜欢
    </label>
  </div>

  
</form>

cursor: pointer;
}
.radio-inline + .radio-inline,
.checkbox-inline + .checkbox-inline {
margin-top: 0;
margin-left: 10px;
}
水平排列源码

5.控件大小：类名input-sm:让控件比正常大小更小；类名input-lg:让控件比正常大小更大；宽度配合Bootstrap的网格系统

.input-sm {
height: 30px;
padding: 5px 10px;
font-size: 12px;
line-height: 1.5;
border-radius: 3px;
}
select.input-sm {
height: 30px;
line-height: 30px;
}
textarea.input-sm,
select[multiple].input-sm {
height: auto;
}
.input-lg {
height: 46px;
padding: 10px 16px;
font-size: 18px;
line-height: 1.33;
border-radius: 6px;
}
select.input-lg {
height: 46px;
line-height: 46px;
}
textarea.input-lg,
select[multiple].input-lg {
height: auto;
}
源码

6.表单控件状态（焦点状态）：类名form-control

.form-control:focus {
border-color: #66afe9;
outline: 0;
  -webkit-box-shadow: inset 0 1px 1pxrgba(0,0,0,.075), 0 0 8px rgba(102, 175, 233, .6);
box-shadow: inset 0 1px 1pxrgba(0,0,0,.075), 0 0 8px rgba(102, 175, 233, .6);
}
源码

7.表单控件状态(禁用状态)：form-control别忘记加①在需要禁用的表单控件上加上“disabled”；②fieldset设置了disabled属性，整个域都将处于被禁用状态。

.form-control[disabled],
.form-control[readonly],
fieldset[disabled] .form-control {
cursor: not-allowed;
background-color: #eee;
opacity: 1;
}
源码

8.表单控件状态(验证状态):1、.has-warning:警告状态（黄色）  2、.has-error：错误状态（红色） 3、.has-success：成功状态（绿色）

：需要类名has-feedback    +     <span class="glyphicon glyphicon-remove form-control-feedback"></span>

9.表单提示信息："help-block"      

.help-block {
display: block;
margin-top: 5px;
margin-bottom: 10px;
color: #737373;
}
源码

图像   1.img-responsive：响应式图片，主要针对于响应式设计    2.img-rounded：圆角图片    3.img-circle：圆形图片    4.img-thumbnail：缩略图片 

img {
vertical-align: middle;
}
.img-responsive,
