<pclass="lead">Baseline is Twitter's toolkit for kickstarting CSS for websites, apps, and more. It includes base CSS styles for typography, forms, buttons, tables, grids, navigation, alerts, and more.</p>
<p>You can use Twitter Baseline in one of two ways: just drop the compiled CSS into any new project and start cranking, or run LESS on your site and compile on the fly like a boss.</p>
</div>
<divclass="span12 columns">
<h3>1. Compiled CSS</h3>
<p>Use this option if you want all the styles of Baseline, but none of the extra power of LESS.</p>
<p><ahref="http://markdotto.com/bootstrap/">Bootstrap</a> is a super awesome pack of mixins and variables to be used in conjunction with <ahref="http://lesscss.org"target="_blank">LESS</a>, a CSS preprocessor for faster and easier web development, that we used to build Baseline.</p>
<p>Here are some of the highlights of what's included in Twitter Baseline as part of Bootstrap. Head over to the Bootstrap website or Github project page to download and learn more.</p>
<p>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.</p>
<p>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 <code>box-shadow</code>, cross-browser gradients, font stacks, and more. Below is a sample of the mixins that are included with Bootstrap in Baseline.</p>
<p>The default grid system provided as part of Baseline 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.</p>
<p>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.</p>
<p>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.</p>
<p>Using emphasis, addresses, & abbreviations</p>
<p>
<code><strong></code>
<code><em></code>
<code><address></code>
<code><abbr></code>
</p>
</div>
<divclass="span12 columns">
<h4>When to use</h4>
<p>Emphasis tags (<code><strong></code> and <code><em></code>) should be used to add visual distinction between a word or phrase and its surrounding copy. Use <code><strong></code> for plain old attention and <code><em></code> for <em>slick</em> attention and titles.</p>
<h3>Emphasis in a paragraph</h3>
<p><ahref="">Fusce dapibus</a>, <strong>tellus ac cursus commodo</strong>, <em>tortor mauris condimentum nibh</em>, ut fermentum massa justo sit amet risus. Maecenas faucibus mollis interdum. Nulla vitae elit libero, a pharetra augue.</p>
<h3>Addresses</h3>
<p>The <code>address</code> element is used for—you guessed it!—addresses. Here's how it looks:</p>
<address>
<strong>Twitter, Inc.</strong><br/>
795 Folsom Ave, Suite 600<br/>
San Francisco, CA 94107<br/>
<abbrtitle="Phone">P:</abbr> (123) 456-7890
</address>
<p><strong>Note:</strong> Each line in an <code>address</code> must end with a line-break (<code><br /></code>) to properly structure the content as it is read in real life without any styles applied.</p>
<h3>Abbreviations</h3>
<p>For abbreviations and acronyms, use the <code>abbr</code> tag (<code>acronym</code> is deprecated in <abbrtitle="HyperText Markup Langugage 5">HTML5</abbr>). Put the shorthand form within the tag and set a title for the complete name.</p>
</div>
</div>
<divclass="row">
<divclass="span4 columns">
<h2>Blockquotes</h2>
<p>
<code><blockquote></code>
<code><p></code>
<code><cite></code>
</p>
</div>
<divclass="span12 columns">
<p>Be sure to wrap your <code>blockquote</code> around <code>paragraph</code> and <code>cite</code> tags. When citing a source, use the <code>cite</code> element. The CSS will automatically preface a name with an em dash (&mdash;).</p>
<blockquote>
<p>Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua...</p>
<h1>Tables <small>For, you guessed it, tabular data</small></h1>
</div>
<divclass="row">
<divclass="span4 columns">
<h2>Building tables</h2>
<p>
<code><table></code>
<code><thead></code>
<code><tbody></code>
<code><tr></code>
<code><th></code>
<code><td></code>
<code><colspan></code>
<code><caption></code>
</p>
<p>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.</p>
<p>Always wrap your column headers in a <code>thead</code> such that hierarchy is <code>thead</code> > <code>tr</code> > <code>th</code>.</p>
<p>Similar to the column headers, all your table's body content should be wrapped in a <code>tbody</code> so your hierarchy is <code>tbody</code> > <code>tr</code> > <code>td</code>.</p>
</ul>
</div>
<divclass="span12 columns">
<h3>Example: Default table styles</h3>
<p>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.</p>
<table>
<thead>
<tr>
<th>#</th>
<th>First Name</th>
<th>Last Name</th>
<th>Language</th>
</tr>
</thead>
<tbody>
<tr>
<td>1</td>
<td>Your</td>
<td>Mom</td>
<td>English</td>
</tr>
<tr>
<td>2</td>
<td>Joe</td>
<td>Sixpack</td>
<td>English</td>
</tr>
<tr>
<td>3</td>
<td>Stu</td>
<td>Dent</td>
<td>Code</td>
</tr>
</tbody>
</table>
<preclass="html">
<table class="common-table">
...
</table></pre>
<h3>Example: Zebra-striped</h3>
<p>Get a little fancy with your tables by adding zebra-striping—just add the <code>.zebra-striped</code> class.</p>
<tableclass="zebra-striped">
<thead>
<tr>
<th>#</th>
<th>First Name</th>
<th>Last Name</th>
<th>Language</th>
</tr>
</thead>
<tbody>
<tr>
<td>1</td>
<td>Your</td>
<td>Mom</td>
<td>English</td>
</tr>
<tr>
<td>2</td>
<td>Joe</td>
<td>Sixpack</td>
<td>English</td>
</tr>
<tr>
<td>3</td>
<td>Stu</td>
<td>Dent</td>
<td>Code</td>
</tr>
</tbody>
</table>
<preclass="html">
<table class="common-table zebra-striped">
...
</table></pre>
<h3>Example: Zebra-striped w/ TableSorter.js</h3>
<p>Taking the previous example, we improve the usefulness of our tables by providing sorting functionality via <ahref="http://jquery.com">jQuery</a> and the <ahref="http://tablesorter.com/docs/">Tablesorter</a> plugin. <strong>Click any column's header to change the sort.</strong></p>
<p>All forms are given default styles to present them in a readable and scalable way. Styles are provided for text inputs, select lists, textareas, radio buttons and checkboxes, and buttons.</p>
<p>Add <code>.form-stacked</code> to your form's HTML and you'll have labels on top of their fields instead of to their left. This works great if your forms are short or you have two columns of inputs for heavier forms.</p>
<p>As a convention, buttons are used for actions while links are used for objects. For instance, "Download" could be a button and "recent activity" could be a link.</p>
<p>All buttons default to a light gray style, but a blue <code>.primary</code> class is available. Plus, rolling your own styles is easy peasy.</p>
</div>
<divclass="span12 columns">
<h3>Example buttons</h3>
<p>Button styles can be applied to anything with the <code>.btn</code> applied. Typically you'll want to apply these to only <code>a</code>, <code>button</code>, and select <code>input</code> elements. Here's how it looks:</p>
<p>Create simple secondary navigation with a <code>ul</code>. Swap between tabs or pills by adding the appropriate class.</p>
<p>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.</p>
<p>Ultra simplistic and minimally styled pagination inspired by Rdio. The large block is hard to miss, easily scalable, and provides large click areas.</p>
<h1>Alerts & Errors <small>Styles for success, warning, and error messages or alerts</small></h1>
</div>
<divclass="row">
<divclass="span4 columns">
<h2>Basic alerts</h2>
<p>One-line messages for highlighting the failure, possible failure, or success of an action. Particularly useful for forms.</p>
</div>
<divclass="span12 columns">
<divclass="alert-message error">
<aclass="close"href="#">×</a>
<p><strong>Oh snap!</strong> Change this and that and try again.</p>
</div>
<divclass="alert-message warning">
<aclass="close"href="#">×</a>
<p><strong>Holy gaucamole!</strong> Best check yo self, you're not looking too good.</p>
</div>
<divclass="alert-message success">
<aclass="close"href="#">×</a>
<p><strong>Well done!</strong> You successfully read this alert message.</p>
</div>
<divclass="alert-message info">
<aclass="close"href="#">×</a>
<p><strong>Heads up!</strong> This is an alert that needs your attention, but it's not a huge priority just yet.</p>
</div>
</div>
</div>
<divclass="row">
<divclass="span4 columns">
<h2>Block messages</h2>
<p>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.</p>
</div>
<divclass="span12 columns">
<divclass="alert-message block-message error">
<aclass="close"href="#">×</a>
<p><strong>Oh snap! You got an error!</strong> 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.</p>
<p><aclass="btn small"href="#">Take This Action</a><aclass="btn small"href="#">Or Do This</a></p>
</div>
<divclass="alert-message block-message warning">
