  • 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">

          记住密码
        </label>
      </div>
      <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

      </div>
    
      
    </form>     
    </body>
    </html>
    示例
    .radio,
    .checkbox {
    display: block;
    min-height: 20px;
    padding-left: 20px;
    margin-top: 10px;
    margin-bottom: 10px;
    }
    .radio label,
    .checkbox label {
    display: inline;
    font-weight: normal;
    cursor: pointer;
    }
    .radio input[type="radio"],
    .radio-inline input[type="radio"],
    .checkbox input[type="checkbox"],
    .checkbox-inline input[type="checkbox"] {
    float: left;
    margin-left: -20px;
    }
    .radio + .radio,
    .checkbox + .checkbox {
    margin-top: -5px;
    }
    源码
    .radio-inline,
    .checkbox-inline {
    display: inline-block;
    padding-left: 20px;

    .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

    按钮

    建议使用button或a标签来制作按钮

    1.基本按钮:类名“btn”

    .btn {
    display: inline-block;
    padding: 6px 12px;
    margin-bottom: 0;
    font-size: 14px;
    font-weight: normal;
    line-height: 1.42857143;

    源码

    2.默认按钮: 类名“btn”  +  类名“btn-default”    

    .btn-default {
    color: #333;
    background-color: #fff;
    border-color: #ccc;
    }
    源码
    3.定制风格:
         

    4.按钮大小: .btn-lg:大型按钮    .btn-sm:小型按钮    .btn-cs:超小型按钮   

    .btn-lg,
    .btn-group-lg> .btn {
    padding: 10px 16px;
    font-size: 18px;
    line-height: 1.33;
    border-radius: 6px;
    }
    .btn-sm,
    .btn-group-sm> .btn {
    padding: 5px 10px;
    font-size: 12px;
    line-height: 1.5;
    border-radius: 3px;
    }
    .btn-xs,
    .btn-group-xs> .btn {
    padding: 1px 5px;
    font-size: 12px;
    line-height: 1.5;
    border-radius: 3px;
    }
    源码

    5.块状按钮: 类名“btn-block”

    6.禁用状态: 使用disabled类或disabled属性

    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,
    .thumbnail>img,
    .thumbnail a >img,
    .carousel-inner > .item >img,
    .carousel-inner > .item > a >img {
    display: block;

    display: inline-block;
    max- 100%;
    height: auto;
    padding: 4px;
    line-height: 1.42857143;
    background-color: #fff;
    border: 1px solid #ddd;
    border-radius: 4px;
      -webkit-transition: all .2s ease-in-out;
    transition: all .2s ease-in-out;
    }
    .img-circle {
    border-radius: 50%;
    }
