Bootsrap中的表格、表单、按钮、图片

1.表格

为任意 <table> 标签添加 .table 类

普通

<table class="table" border="" cellspacing="" cellpadding="">
 <tr><th>#</th><th>Header</th><th>Header</th><th>Header</th></tr>
 <tr><td>1</td><td>Data</td><td>Data</td><td>Data</td></tr>
 <tr><td>2</td><td>Data</td><td>Data</td><td>Data</td></tr>
</table>

条纹状  .table-striped

<table class="table table-striped" border="" cellspacing="" cellpadding="">
 <tr><th>#</th><th>Header</th><th>Header</th><th>Header</th></tr>
 <tr><td>1</td><td>Data</td><td>Data</td><td>Data</td></tr>
 <tr><td>2</td><td>Data</td><td>Data</td><td>Data</td></tr>
 <tr><td>3</td><td>Data</td><td>Data</td><td>Data</td></tr>
 <tr><td>4</td><td>Data</td><td>Data</td><td>Data</td></tr>
</table>

 带边框的表格  

添加 .table-bordered 类为表格和其中的每个单元格增加边框。

<table class="table table-bordered">
  ...
</table>

鼠标悬停改变状态  

通过添加 .table-hover 类可以让 <tbody> 中的每一行对鼠标悬停状态作出响应

<table class="table table-hover">
  ...
</table>

为行或者单元格设置颜色

Class	描述
.active	鼠标悬停在行或单元格上时所设置的颜色
.success	标识成功或积极的动作
.info	标识普通的提示信息或动作
.warning	标识警告或需要用户注意
.danger	标识危险或潜在的带来负面影响的动作

<!-- On rows -->
<tr class="active">...</tr>
<tr class="success">...</tr>
<tr class="warning">...</tr>
<tr class="danger">...</tr>
<tr class="info">...</tr>

<!-- On cells (`td` or `th`) -->
<tr>
  <td class="active">...</td>
  <td class="success">...</td>
  <td class="warning">...</td>
  <td class="danger">...</td>
  <td class="info">...</td>
</tr>

响应式表格

将任何 .table 元素包裹在 .table-responsive 元素内

<div class="table-responsive">
  <table class="table">
    ...
  </table>
</div>

2. 表单

普通表单

<form>
  <div class="form-group">
    <label for="exampleInputEmail1">Email address</label>
    <input type="email" class="form-control" id="exampleInputEmail1" placeholder="Email">
  </div>
  <div class="form-group">
    <label for="exampleInputPassword1">Password</label>
    <input type="password" class="form-control" id="exampleInputPassword1" placeholder="Password">
  </div>
  <div class="form-group">
    <label for="exampleInputFile">File input</label>
    <input type="file" id="exampleInputFile">
    <p class="help-block">Example block-level help text here.</p>
  </div>
  <div class="checkbox">
    <label>
      <input type="checkbox"> Check me out
    </label>
  </div>
  <button type="submit" class="btn btn-default">Submit</button>
</form>

不要将表单组和输入框组混合使用

内联表单

<form class="form-inline">
  <div class="form-group">
    <label for="exampleInputName2">Name</label>
    <input type="text" class="form-control" id="exampleInputName2" placeholder="Jane Doe">
  </div>
  <div class="form-group">
    <label for="exampleInputEmail2">Email</label>
    <input type="email" class="form-control" id="exampleInputEmail2" placeholder="[email protected]">
  </div>
  <button type="submit" class="btn btn-default">Send invitation</button>
</form>

<form class="form-inline">
  <div class="form-group">
    <label class="sr-only" for="exampleInputEmail3">Email address</label>
    <input type="email" class="form-control" id="exampleInputEmail3" placeholder="Email">
  </div>
  <div class="form-group">
    <label class="sr-only" for="exampleInputPassword3">Password</label>
    <input type="password" class="form-control" id="exampleInputPassword3" placeholder="Password">
  </div>
  <div class="checkbox">
    <label>
      <input type="checkbox"> Remember me
    </label>
  </div>
  <button type="submit" class="btn btn-default">Sign in</button>
</form>

<form class="form-inline">
  <div class="form-group">
    <label class="sr-only" for="exampleInputAmount">Amount (in dollars)</label>
    <div class="input-group">
      <div class="input-group-addon">$</div>
      <input type="text" class="form-control" id="exampleInputAmount" placeholder="Amount">
      <div class="input-group-addon">.00</div>
    </div>
  </div>
  <button type="submit" class="btn btn-primary">Transfer cash</button>
</form>

 

<form class="form-horizontal">
  <div class="form-group">
    <label for="inputEmail3" class="col-sm-2 control-label">Email</label>
    <div class="col-sm-10">
      <input type="email" class="form-control" id="inputEmail3" placeholder="Email">
    </div>
  </div>
  <div class="form-group">
    <label for="inputPassword3" class="col-sm-2 control-label">Password</label>
    <div class="col-sm-10">
      <input type="password" class="form-control" id="inputPassword3" placeholder="Password">
    </div>
  </div>
  <div class="form-group">
    <div class="col-sm-offset-2 col-sm-10">
      <div class="checkbox">
        <label>
          <input type="checkbox"> Remember me
        </label>
      </div>
    </div>
  </div>
  <div class="form-group">
    <div class="col-sm-offset-2 col-sm-10">
      <button type="submit" class="btn btn-default">Sign in</button>
    </div>
  </div>
</form>

输入框  输入类型

 text、password、datetime、datetime-local、date、month、time、week、number、email、url、search、tel 和 color。

在这里都可以加上  .form-control  就会有相应的样式

<input type="text" class="form-control" placeholder="Text input">

文本域也可以

 

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

下拉列表 select 

 

<select class="form-control">
  <option>1</option>
  <option>2</option>
  <option>3</option>
  <option>4</option>
  <option>5</option>
</select>

只读状态

<input class="form-control" type="text" placeholder="Readonly input here…" readonly>

3.按钮

<!-- Standard button -->
<button type="button" class="btn btn-default">（默认样式）Default</button>

<!-- Provides extra visual weight and identifies the primary action in a set of buttons -->
<button type="button" class="btn btn-primary">（首选项）Primary</button>

<!-- Indicates a successful or positive action -->
<button type="button" class="btn btn-success">（成功）Success</button>

<!-- Contextual button for informational alert messages -->
<button type="button" class="btn btn-info">（一般信息）Info</button>

<!-- Indicates caution should be taken with this action -->
<button type="button" class="btn btn-warning">（警告）Warning</button>

<!-- Indicates a dangerous or potentially negative action -->
<button type="button" class="btn btn-danger">（危险）Danger</button>

<!-- Deemphasize a button by making it look like a link while maintaining button behavior -->
<button type="button" class="btn btn-link">（链接）Link</button>

使用 .btn-lg、.btn-sm 或 .btn-xs 就可以获得不同尺寸的按钮。

<p>
  <button type="button" class="btn btn-primary btn-lg">（大按钮）Large button</button>
  <button type="button" class="btn btn-default btn-lg">（大按钮）Large button</button>
</p>
<p>
  <button type="button" class="btn btn-primary">（默认尺寸）Default button</button>
  <button type="button" class="btn btn-default">（默认尺寸）Default button</button>
</p>
<p>
  <button type="button" class="btn btn-primary btn-sm">（小按钮）Small button</button>
  <button type="button" class="btn btn-default btn-sm">（小按钮）Small button</button>
</p>
<p>
  <button type="button" class="btn btn-primary btn-xs">（超小尺寸）Extra small button</button>
  <button type="button" class="btn btn-default btn-xs">（超小尺寸）Extra small button</button>
</p>

通过给按钮添加 .btn-block 类可以将其拉伸至父元素100%的宽度，而且按钮也变为了块级（block）元素。

<button type="button" class="btn btn-primary btn-lg btn-block">（块级元素）Block level button</button>
<button type="button" class="btn btn-default btn-lg btn-block">（块级元素）Block level button</button>

为 <button> 元素添加 disabled 属性，使其表现出禁用状态。 

为基于 <a> 元素创建的按钮添加 .disabled 类。

<a href="#" class="btn btn-primary btn-lg disabled" role="button">Primary link</a>
<a href="#" class="btn btn-default btn-lg disabled" role="button">Link</a>

4.图片

 响应式图片

通过为图片添加 .img-responsive 类可以让图片支持响应式布局。其实质是为图片设置了 max-width: 100%;、 height: auto; 和 display: block; 属性，从而让图片在其父元素中更好的缩放。

如果需要让使用了 .img-responsive 类的图片水平居中，请使用 .center-block 类

<img src="..." class="img-responsive" alt="Responsive image">

<img src="..." alt="..." class="img-rounded">
<img src="..." alt="..." class="img-circle">
<img src="..." alt="..." class="img-thumbnail">

文本颜色

<p class="text-muted">...</p>
<p class="text-primary">...</p>
<p class="text-success">...</p>
<p class="text-info">...</p>
<p class="text-warning">...</p>
<p class="text-danger">...</p>

背景色类
