As a convention, buttons should only be used for actions while hyperlinks are to be used for objects. For instance, "Download" should be a button while "recent activity" should be a link.

Button styles can be applied to anything with the .btn class applied. However, typically you'll want to apply these to only <a> and <button> elements.

IE9 doesn't crop background gradients on rounded corners, so we remove it. Related, IE9 jankifies disabled button elements, rendering text gray with a nasty text-shadow that we cannot fix.

Fancy larger or smaller buttons? Add .btn-large, .btn-small, or .btn-mini for two additional sizes.

For disabled buttons, add the .disabled class to links and the disabled attribute for <button> elements.

Primary link Link

Heads up! We use .disabled as a utility class here, similar to the common .active class, so no prefix is required.

幸运飞艇其实是人为控制的

Use the .btn class on an <a>, <button>, or <input> element.

Link
<a class="btn" href="">Link</a>
<button class="btn" type="submit">
  Button
</button>
<input class="btn" type="button"
         value="Input">
<input class="btn" type="submit"
         value="Submit">

As a best practice, try to match the element for you context to ensure matching cross-browser rendering. If you have an input, use an <input type="submit"> for your button.

Instead of making every icon an extra request, we've compiled them into a sprite—a bunch of images in one file that uses CSS to position the images with background-position. This is the same method we use on Twitter.com and it has worked well for us.

All icons classes are prefixed with .icon- for proper namespacing and scoping, much like our other components. This will help avoid conflicts with other tools.

Glyphicons has granted us use of the Halflings set in our open-source toolkit so long as we provide a link and credit here in the docs. Please consider doing the same in your projects.

幸运飞艇其实是人为控制的

Bootstrap uses an <i> tag for all icons, but they have no case class—only a shared prefix. To use, place the following code just about anywhere:

<i class="icon-search"></i>

There are also styles available for inverted (white) icons, made ready with one extra class:

<i class="icon-search icon-white"></i>

There are 120 classes to choose from for your icons. Just add an <i> tag with the right classes and you're set. You can find the full list in sprites.less or right here in this document.

Heads up! When using beside strings of text, as in buttons or nav links, be sure to leave a space after the <i> tag for proper spacing.

幸运飞艇其实是人为控制的

Icons are great, but where would one use them? Here are a few ideas:

  • As visuals for your sidebar navigation
  • For a purely icon-driven navigation
  • For buttons to help convey the meaning of an action
  • With links to share context on a user's destination

Essentially, anywhere you can put an <i> tag, you can put an icon.

幸运飞艇其实是人为控制的

Use them in buttons, button groups for a toolbar, navigation, or prepended form inputs.

幸运飞艇其实是人为控制的

The best part about forms in Bootstrap is that all your inputs and controls look great no matter how you build them in your markup. No superfluous HTML is required, but we provide the patterns for those who require it.

More complicated layouts come with succinct and scalable classes for easy styling and event binding, so you're covered at every step.

幸运飞艇其实是人为控制的

Bootstrap comes with support for four types of form layouts:

  • Vertical (default)
  • Search
  • Inline
  • Horizontal

Different types of form layouts require some changes to markup, but the controls themselves remain and behave the same.

幸运飞艇其实是人为控制的

Bootstrap's forms include styles for all the base form controls like input, textarea, and select you'd expect. But it also comes with a number of custom components like appended and prepended inputs and support for lists of checkboxes.

States like error, warning, and success are included for each type of form control. Also included are styles for disabled controls.

幸运飞艇其实是人为控制的

Bootstrap provides simple markup and styles for four styles of common web forms.

Name Class Description
Vertical (default) .form-vertical (not required) Stacked, left-aligned labels over controls
Inline .form-inline Left-aligned label and inline-block controls for compact style
Search .form-search Extra-rounded text input for a typical search aesthetic
Horizontal .form-horizontal Float left, right-aligned labels on same line as controls

Example forms using just form controls, no extra markup欧冠直播万博app

幸运飞艇其实是人为控制的

With v2.0, we have lighter and smarter defaults for form styles. No extra markup, just form controls.

Associated help text!

Example block-level help text here.

<form class="well">
  <label>Label name</label>
  <input type="text" class="span3" placeholder="Type something">
  <span class="help-inline">Associated help text!</span>
  <label class="checkbox">
    <input type="checkbox"> Check me out
  </label>
  <button type="submit" class="btn">Submit</button>
</form>

幸运飞艇其实是人为控制的

Reflecting default WebKit styles, just add .form-search for extra rounded search fields.

<form class="well form-search">
  <input type="text" class="input-medium search-query">
  <button type="submit" class="btn">Search</button>
</form>

幸运飞艇其实是人为控制的

Inputs are block level to start. For .form-inline and .form-horizontal, we use inline-block.

<form class="well form-inline">
  <input type="text" class="input-small" placeholder="Email">
  <input type="password" class="input-small" placeholder="Password">
  <label class="checkbox">
    <input type="checkbox"> Remember me
  </label>
  <button type="submit" class="btn">Sign in</button>
</form>

Controls Bootstrap supports

In addition to freeform text, any HTML5 text-based input appears like so.

幸运飞艇其实是人为控制的

Given the above example form layout, here's the markup associated with the first input and control group. The .control-group, .control-label, and .controls classes are all required for styling.

<form class="form-horizontal">
  <fieldset>
    <legend>Legend text</legend>
    <div class="control-group">
      <label class="control-label" for="input01">Text input</label>
      <div class="controls">
        <input type="text" class="input-xlarge" id="input01">
        <p class="help-block">Supporting help text</p>
      </div>
    </div>
  </fieldset>
</form>

幸运飞艇其实是人为控制的

Shown on the left are all the default form controls we support. Here's the bulleted list:

  • text inputs (text, password, email, etc)
  • checkbox
  • radio
  • select
  • multiple select
  • file input
  • textarea

幸运飞艇其实是人为控制的

Up to v1.4, Bootstrap's default form styles used the horizontal layout. With Bootstrap 2, we removed that constraint to have smarter, more scalable defaults for any form.


Form control states
Some value here
Something may have gone wrong
Please correct the error
Woohoo!
Woohoo!

幸运飞艇其实是人为控制的

Bootstrap features styles for browser-supported focused and disabled states. We remove the default Webkit outline and apply a box-shadow in its place for :focus.


幸运飞艇其实是人为控制的

It also includes validation styles for errors, warnings, and success. To use, add the error class to the surrounding .control-group.

<fieldset
  class="control-group error">
  
</fieldset>

Extending form controls

Use the same .span* classes from the grid system for input sizes.

You may also use static classes that don't map to the grid, adapt to the responsive CSS styles, or account for varying types of controls (e.g., input vs. select).

@

Here's some help text

.00
Here's more help text

Note: Labels surround all the options for much larger click areas and a more usable form.

Input groups—with appended or prepended text—provide an easy way to give more context for your inputs. Great examples include the @ sign for Twitter usernames or $ for finances.


幸运飞艇其实是人为控制的

Up to v1.4, Bootstrap required extra markup around checkboxes and radios to stack them. Now, it's a simple matter of repeating the <label class="checkbox"> that wraps the <input type="checkbox">.

Inline checkboxes and radios are also supported. Just add .inline to any .checkbox or .radio and you're done.

To use prepend or append inputs in an inline form, be sure to place the .add-on and input on the same line, without spaces.

To add help text for your form inputs, include inline help text with <span class="help-inline"> or a help text block with <p class="help-block"> after the input element.

Wrap inline snippets of code with <code>.

For example, <code>section</code> should be wrapped as inline.

Use <pre> for multiple lines of code. Be sure to escape any angle brackets in the code for proper rendering.

<p>Sample text here...</p>
<pre>
  &lt;p&gt;Sample text here...&lt;/p&gt;
</pre>

Note: Be sure to keep code within <pre> tags as close to the left as possible; it will render all tabs.

You may optionally add the .pre-scrollable class which will set a max-height of 350px and provide a y-axis scrollbar.

幸运飞艇其实是人为控制的

Take the same <pre> element and add two optional classes for enhanced rendering.

<p>Sample text here...</p>
<pre class="prettyprint
     linenums">
  &lt;p&gt;Sample text here...&lt;/p&gt;
</pre>

Use button groups to join multiple buttons together as one composite component. Build them with a series of <a> or <button> elements.

幸运飞艇其实是人为控制的

We recommend the following guidelines for using button groups and toolbars:

  • Always use the same element in a single button group, <a> or <button>.
  • Don't mix buttons of different colors in the same button group.
  • Use icons in addition to or instead of text, but be sure include alt and title text where appropriate.

Related Button groups with dropdowns (see below) should be called out separately and always include a dropdown caret to indicate intended behavior.

幸运飞艇其实是人为控制的

Here's how the HTML looks for a standard button group built with anchor tag buttons:

<div class="btn-group">
  <button class="btn">1</button>
  <button class="btn">2</button>
  <button class="btn">3</button>
</div>

幸运飞艇其实是人为控制的

Combine sets of <div class="btn-group"> into a <div class="btn-toolbar"> for more complex components.

<div class="btn-toolbar">
  <div class="btn-group">

  </div>
</div>

幸运飞艇其实是人为控制的

Button groups can also function as radios, where only one button may be active, or checkboxes, where any number of buttons may be active. View the Javascript docs for that.

Heads up! Buttons with dropdowns must be individually wrapped in their own .btn-group within a .btn-toolbar for proper rendering.

欧冠直播万博app

幸运飞艇其实是人为控制的

Similar to a button group, our markup uses regular button markup, but with a handful of additions to refine the style and support Bootstrap's dropdown jQuery plugin.

<div class="btn-group">
  <a class="btn dropdown-toggle" data-toggle="dropdown" href="#">
    Action
    <span class="caret"></span>
  </a>
  <ul class="dropdown-menu">
    <!-- dropdown menu links -->
  </ul>
</div>

幸运飞艇其实是人为控制的

Button dropdowns work at any size. your button sizes to .btn-large, .btn-small, or .btn-mini.

幸运飞艇其实是人为控制的

Button dropdowns require the Bootstrap dropdown plugin to function.

In some cases—like mobile—dropdown menus will extend outside the viewport. You need to resolve the alignment manually or with custom javascript.

幸运飞艇其实是人为控制的

Building on the button group styles and markup, we can easily create a split button. Split buttons feature a standard action on the left and a dropdown toggle on the right with contextual links.

幸运飞艇其实是人为控制的

Utilize the extra button classe .btn-mini, .btn-small, or .btn-large for sizing.

<div class="btn-group">
  ...
  <ul class="dropdown-menu pull-right">
    <!-- dropdown menu links -->
  </ul>
</div>

幸运飞艇其实是人为控制的

We expand on the normal button dropdowns to provide a second button action that operates as a separate dropdown trigger.

<div class="btn-group">
  <button class="btn">Action</button>
  <button class="btn dropdown-toggle" data-toggle="dropdown">
    <span class="caret"></span>
  </button>
  <ul class="dropdown-menu">
    <!-- dropdown menu links -->
  </ul>
</div>

幸运飞艇其实是人为控制的

Dropdown menus can also be toggled from the bottom up by adding a single class to the immediate parent of .dropdown-menu. It will flip the direction of the .caret and reposition the menu itself to move from the bottom up instead of top down.

<div class="btn-group dropup">
  <button class="btn">Dropup</button>
  <button class="btn dropdown-toggle" data-toggle="dropdown">
    <span class="caret"></span>
  </button>
  <ul class="dropdown-menu">
    <!-- dropdown menu links -->
  </ul>

Ultra simplistic and minimally styled pagination inspired by Rdio, great for apps and search results. The large block is hard to miss, easily scalable, and provides large click areas.

Pager For quick previous and next links欧冠直播万博app

幸运飞艇其实是人为控制的

The pager component is a set of links for simple pagination implementations with light markup and even lighter styles. It's great for simple sites like blogs or magazines.

Pager links also use the general .disabled class from the pagination.

By default, the pager centers links.

    <a href="#">Previous</a>
  </li>
  <li>

With Bootstrap 2, we've simplified the base class: .alert instead of .alert-message. We've also reduced the minimum required markup—no <p> is required by default, just the outer <div>.

幸运飞艇其实是人为控制的

For a more durable component with less code, we've removed the differentiating look for block alerts, messages that come with more padding and typically more text. The class also has changed to .alert-block.
