default grid

The default grid system provided as part of Bootstrap is a 940px wide 16-column grid. It's a flavor of the popular 960 grid system, but without the additional margin/padding on the left and right sides.

Example grid markup

As shown here, a basic layout can be created with two "columns," each spanning a number of the 16 foundational columns we defined as part of our grid system. See the examples below for more variations.

<div class = "row" > 
  <div class = "span6 columns" > 
    ...
  </div>
  <div class = "span10 columns" > 
    ...
  </div>
</div>

one

four

eight

eleven

offset columns

four

8 offset 4

4 offset 4

5 offset 3

10 offset 6

fixed layout

A basic 940px wide, centered container layout for just about any site or page.

<body>
  <div class = "container" > 
    ...
  </div>
</body>

fluid layout

A flexible fluid or liquid page structure with min- and max-widths and a left-hand sidebar. Great for apps.

<body>
  <div class = "container-fluid" > 
    <div class = "sidebar" > 
      ...
    </div>
    <divclass = " content" > 
      ...
    </div>
  </div>
</body>

Headings and copy

A standard typographic hierarchy for structuring your webpages.

h1. heading 1

h2. Heading 2

h3. heading 3

h4. heading 4

h5. heading 5

h6. heading 6

example paragraph

Nullam quis risus eget urna mollis ornare vel eu leo. Cum sociis natoque penatibus et magnis dis parturient montes, nascetur ridiculus mus. Nullam id dolor id nibh ultricies vehicula ut id elit.

Example heading Has sub-heading...

You can also add subheadings with the <strong>and<em>

misc. elements

Using emphasis, addresses, & abbreviations

<strong> <em> <address> <abbr>

When to use

Emphasis tags ( <strong>and <em>) should be used to add visual distinction between a word or phrase and its surrounding copy. Use <strong>for plain old attention and <em>for slick attention and titles.

Emphasis in a paragraph

Fusce dapibus , tellus ac cursus commodo , tortor mauris condimentum nibh , ut fermentum massa justo sit ametrisus. Maecenas faucibus mollis interdum. Nulla vitae elit libero, a pharetra augue.

Addresses

The addresselement is used for—you guessed it!—addresses. Here's how it looks:

Twitter Inc.
795 Folsom Ave, Suite 600
San Francisco, CA 94107
P: (123) 456-7890

Note: Each line in an addressmust end with a line-break ( <br />) to properly structure the content as it is read in real life without any styles applied.

Abbreviations

For abbreviations and acronyms, use the abbrtag ( acronymis deprecated in HTML5 ). Put the shorthand form within the tag and set a title for the complete name.

Blockquotes

<blockquote> <p> <cite>

Be sure to wrap your blockquotearound paragraphand citetags. When citing a source, use the citeelement. The CSS will automatically preface a name with an em dash (—).

building tables

<table> <thead> <tbody> <tr> <th> <td> <colspan> <caption>

Tables are great—for a lot of things. Great tables, however, need a bit of markup love to be useful, scalable, and readable (at the code level). Here are a few tips to help.

Always wrap your column headers in a theadsuch that hierarchy is thead> tr> th.

Similar to the column headers, all your table's body content should be wrapped in a tbodyso your hierarchy is tbody> tr> td.

Example: Default table styles

All tables will be automatically styled with only the essential borders to ensure readability and maintain structure. No need to add extra classes or attributes.

#	first name	last name	language
one	Some	One	English
2	Joe	six pack	English
3	Stu	Dent	Code

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

Example: Zebra striped

Get a little fancy with your tables by adding zebra-striping—just add the .zebra-stripedclass.

#	first name	last name	language
one	Some	One	English
2	Joe	six pack	English
3	Stu	Dent	Code

<table class = "common-table zebra-striped" > 
...
</table>

Example: Zebra-striped w/ TableSorter.js

Taking the previous example, we improve the usefulness of our tables by providing sorting functionality via jQuery and the Tablesorter plugin. Click any column's header to change the sort.

#	first name	last name	language
one	Your	One	English
2	Joe	six pack	English
3	Stu	Dent	Code

<script type = "text/javascript" src = "js/jquery/jquery.tablesorter.min.js" ></script>  
<script type = "text/javascript" > 
  $ ( document ). ready ( function () { 
    $ ( "table#sortTableExample" ). tablesorter ( { sortList : [[ 1 , 0 ]]} );   
  });
</script>
<table class = "common-table zebra-striped" > 
  ...
</table>

fixed topbar

What is it

Our topbar is a fixed bar that houses a website's logo or name, primary navigation, and search form.

customizable

All elements within, and the entire topbar as well, are optional. You can choose to include a logo/name, nav, search, and a secondary nav—or any combination of that.

Dropdowns included

As part of the main navigation, we've included the ability for you to add dropdowns to your nav. Check out the secondary nav above (right aligned) to see how it's done.

Tabs and pills

Create simple secondary navigation with a ul. Swap between tabs or pills by adding the appropriate class.

Great for sub-sections of content like our account settings pages and user timelines for toggling between pages of like content. Available in tabbed or pill styles.

<ul class = "tabs" > 
  <li class = "active" ><a href = "" > Home </a></li>  
  <li><a href=""> Profile </a> </ li > 
  <li><a href=""> Messages </a> </ li > 
  <li><a href=""> Settings </a> </ li > 
  <li><a href=""> Contact </a> </ li > 
</ul>

<ul class = "pills" > 
  <li class = "active" ><a href = "" > Home </a></li>  
  <li><a href=""> Profile </a> </ li > 
  <li><a href=""> Messages </a> </ li > 
  <li><a href=""> Settings </a> </ li > 
  <li><a href=""> Contact </a> </ li > 
</ul>

Pagination

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

<div class = "pagination" > 
  <ul>
    <li class = "prev disabled" ><a href = "" > ← Previous </a></li>  
    <li class = "active" ><a href = "" > 1 </a></li>  
    <li><a href=""> 2 </a> </ li > 
    <li><a href=""> 3 </a> </ li > 
    <li><a href=""> 4 </a> </ li > 
    <li><a href=""> 5 </a> </ li > 
    <li class = "next" ><a href = "" > Next → </a></li>  
  </ul>
</div>

Basic alerts

One-line messages for highlighting the failure, possible failure, or success of an action. Particularly useful for forms.

Oh snap! Change this and that and try again.

Holy gaucamole! Best check yo self, you're not looking too good.

Well done! You successfully read this alert message.

Head up! This is an alert that needs your attention, but it's not a huge priority just yet.

block messages

For messages that require a bit of explanation, we have paragraph style alerts. These are perfect for bubbling up longer error messages, warning a user of a pending action, or just presenting information for more emphasis on the page.

Oh snap! You got an error!Change this and that and try again. Duis mollis, est non commodo luctus, nisi erat porttitor ligula, eget lacinia odio sem nec elit. Cras mattis consectetur purus sit amet fermentum.

Take this action Or do this

Holy gaucamole! This is a warning!Best check yo self, you're not looking too good. Nulla vitae elit libero, a pharetra augue. Praesent commodo cursus magna, vel scelerisque nisl consectetur et.

Take this action Or do this

Well done!You successfully read this alert message. Cum sociis natoque penatibus et magnis dis parturient montes, nascetur ridiculus mus. Maecenas faucibus mollis interdum.

Take this action Or do this

Head up!This is an alert that needs your attention, but it's not a huge priority just yet.

Take this action Or do this

Modals

Modals—dialogs or lightboxes—are great for contextual actions in situations where it's important that the background context be maintained.

Tool Tips

Twipsies are super useful for aiding a confused user and pointing them in the right direction.

Lorem ipsum dolar sit amet illo error ipsum veritatis aut iste perspiciatis iste voluptas natus illo quasi odit aut natus consequuntur consequuntur, aut natus illo voluptatem odit perspiciatis laudantium rem doloremque totam voluptas. Voluptasdicta eaque beatae aperiam ut enim voluptatem explicabo explicabo, voluptas quia odit fugit accusantium totam totam architecto explicabo sit quasi fugit fugit, totam doloremque unde sunt sed dicta quae accusantium fugit voluptas nemo voluptas voluptatem rem quae aut vertitas quasi.

Popovers

Use popovers to provide subtextual information to a page without effecting layout.

Bootstrap was built with Preboot , an open-source pack of mixins and variables to be used in conjunction with Less , a CSS preprocessor for faster and easier web development.

Check out how we used Preboot in Bootstrap and how you can make use of it should you choose to run Less on your next project.

How to use it

Use this option to make full use of Bootstrap's Less variables, mixins, and nesting in CSS via javascript in your browser.

<link rel = "stylesheet/less" type = "text/css" href = "less/bootstrap.less" media = "all" />     
<script type = "text/javascript" src = "js/less-1.0.41.min.js" ></script>

Not feeling the .js solution? Try the Less Mac app or use Node.js to compile when you deploy your code.

What's included

Here are some of the highlights of what's included in Twitter Bootstrap as part of Bootstrap. Head over to the Bootstrap website or Github project page to download and learn more.

color variables

Variables in Less are perfect for maintaining and updating your CSS headache free. When you want to change a color value or a frequently used value, update it in one spot and you're set.

// links
@linkColor : #8b59c2;         
@linkColorHover :     darken ( @linkColor , 10 ); 
 
// Grays
@black : #000;             
@grayDark :           lighten ( @black , 25 %); 
@gray :               lighten ( @black , 50 %); 
@grayLight :          lighten ( @black , 70 %); 
@grayLighter :        lighten ( @black , 90 %); 
@white : #fff;             
 
// Accent Colors
@blue : #08b5fb;              
@green : #46a546;             
@red : #9d261d;               
@yellow : #ffc40d;            
@orange : #f89406;            
@pink : #c3325f;              
@purple : #7a43b6;            
 
// baseline
@baseline : 20px ;

Commenting

Less also provides another style of commenting in addition to CSS's normal /* ... */syntax.

// This is a comment
/* This is also a comment */

Mixins up the wazoo

Mixins are basically includes or partials for CSS, allowing you to combine a block of code into one. They're great for vendor prefixed properties like box-shadow, cross-browser gradients, font stacks, and more. Below is a sample of the mixins that are included with Bootstrap.

Font stacks

#font {
  . shorthand ( @weight : normal , @size : 14px , @lineHeight : 20px ) {     
    font - size : @size ; 
    font - weight : @weight ; 
    line - height : @lineHeight ; 
  }
  . sans - serif ( @weight : normal , @size : 14px , @lineHeight : 20px ) {     
    font - family : "Helvetica Neue" , Helvetica , Arial , sans - serif ;   
    font - size : @size ; 
    font - weight : @weight ; 
    line - height : @lineHeight ; 
  }
  . serif ( @weight : normal , @size : 14px , @lineHeight : 20px ) {     
    font - family : "Georgia" , Times New Roman , Times , sans - serif ;     
    font - size : @size ; 
    font - weight : @weight ; 
    line - height : @lineHeight ; 
  }
  . monospace ( @weight : normal , @size : 12px , @lineHeight : 20px ) {     
    font - family : "Monaco" , Courier New , monospace ;   
    font - size : @size ; 
    font - weight : @weight ; 
    line - height : @lineHeight ; 
  }
}

Gradients

#gradient {
  . horizontal ( @startColor : #555, @endColor: #333) { 
    background - color : @endColor ; 
    background - repeat : repeat - x ;
    background - image : - khtml - gradient ( linear , left top , right top , from ( @startColor ), to ( @endColor )); // Konqueror   
    background - image : - moz - linear - gradient ( left , @startColor , @endColor ); //FF 3.6+    
    background - image : - ms - linear - gradient ( left , @startColor , @endColor ); // IE10    
    background - image : - webkit - gradient ( linear , left top , right top , color - stop ( 0 %, @startColor ), color - stop ( 100 %, @endColor )); // Safari 4+, Chrome 2+    
    background - image : - webkit - linear - gradient ( left , @startColor , @endColor ); // Safari 5.1+, Chrome 10+    
    background - image : - o - linear - gradient ( left , @startColor , @endColor ); // Opera 11.10    
    - ms - filter : %( "progid:DXImageTransform.Microsoft.gradient(startColorstr='%d', endColorstr='%d', GradientType=1)" , @startColor , @endColor ); // IE8+  
    filter : e (%( "progid:DXImageTransform.Microsoft.gradient(startColorstr='%d', endColorstr='%d', GradientType=1)" , @startColor , @endColor )); // IE6 & IE7 
    background - image : linear - gradient ( left , @startColor , @endColor ); // Le standard   
  }
  . vertical ( @startColor : #555, @endColor: #333) { 
    background - color : @endColor ; 
    background - repeat : repeat - x ;
    background - image : - khtml - gradient ( linear , left top , left bottom , from ( @startColor ), to ( @endColor )); // Konqueror   
    background - image : - moz - linear - gradient ( @startColor , @endColor ); //FF 3.6+   
    background - image : - ms - linear - gradient ( @startColor , @endColor ); // IE10   
    background - image : - webkit - gradient ( linear , left top , left bottom , color - stop ( 0 %, @startColor ), color - stop ( 100 %, @endColor )); // Safari 4+, Chrome 2+    
    background - image : - webkit - linear - gradient ( @startColor , @endColor ); // Safari 5.1+, Chrome 10+   
    background - image : - o - linear - gradient ( @startColor , @endColor ); // Opera 11.10   
    - ms - filter : %( "progid:DXImageTransform.Microsoft.gradient(startColorstr='%d', endColorstr='%d', GradientType=0)" , @startColor , @endColor ); // IE8+  
    filter : e (%( "progid:DXImageTransform.Microsoft.gradient(startColorstr='%d', endColorstr='%d', GradientType=0)" , @startColor , @endColor )); // IE6 & IE7 
    background - image : linear - gradient ( @startColor , @endColor ); // The standard  
  }
  . directional ( @startColor : #555, @endColor: #333, @deg: 45deg) { 
    ...
  }
  . vertical - three - colors ( @startColor : #00b3ee, @midColor: #7a43b6, @colorStop: 0.5, @endColor: #c3325f) { 
    ...
  }
}

Operations and grid system

Get fancy and perform some math to generate flexible and powerful mixins like the one below.

// grid
@gridColumns : 16 ;       
@gridColumnWidth : 40px ;   
@gridGutterWidth : 20px ;   
 
// Grid System
. container {
  width : @siteWidth ; 
  margin : 0 auto ;  
  . clearfix ();
}
. columns ( @columnSpan : 1 ) {  
  display : inline _ 
  float : left ;
  width : ( @gridColumnWidth * @columnSpan ) + ( @gridGutterWidth * ( @columnSpan - 1 ));         
  margin - left : @gridGutterWidth ; 
  &: first - child {
    margin - left : 0 ; 
  }
}
. offset ( @columnOffset : 1 ) {  
  margin - left : ( @gridColumnWidth * @columnOffset ) + ( @gridGutterWidth * ( @columnOffset - 1 )) ! important ;          
}
