The entire typographic grid is based on two Less variables in our variables.less file: @baseFontSize and @baseLineHeight. The first is the base font-size used throughout and the second is the base line-height.
We use those variables, and some math, to create the margins, paddings, and line-heights of all our type and more.

Fusce dapibus, tellus ac cursus commodo, tortor mauris condimentum nibh, ut fermentum massa justo sit amet risus. Maecenas faucibus mollis interdum. Nulla vitae elit libero, a pharetra augue.
Note: Feel free to use <b> and <i> in HTML5, but their usage has changed a bit. <b> is meant to highlight words or phrases without conveying additional importance while <i> is mostly for voice, technical terms, etc.
Here are two examples of how the <address> tag can be used:
Abbreviations with a title attribute have a light dotted bottom border and a help cursor on hover. This gives users extra indication something will be shown on hover.
Add the initialism class to an abbreviation to increase typographic harmony by giving it a slightly smaller text size.
HTML is the best thing since sliced bread.
An abbreviation of the word attribute is attr.
| Element | Usage | Optional |
|---|---|---|
<blockquote>
|
Block-level element for quoting content from another source |
Add Use |
<small>
|
Optional element for adding a user-facing citation, typically an author with title of work |
Place the <cite> around the title or name of source
|
To include a blockquote, wrap <blockquote> around any HTML as the quote. For straight quotes we recommend a <p>.
Include an optional <small> element to cite your source and you’ll get an em dash — before it for styling purposes.
<blockquote> <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer posuere erat a ante venenatis.</p> <small>Someone famous</small> </blockquote>
Default blockquotes are styled as such:
Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer posuere erat a ante venenatis.
Someone famous in Body of work
To float your blockquote to the right, add class="pull-right":
Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer posuere erat a ante venenatis.
Someone famous in Body of work
<ul>
<ul class="unstyled">
<ol>
<dl>
<dl class="dl-horizontal">
Heads up!
Horizontal description lists will truncate terms that are too long to fit in the left column fix text-overflow. In narrower viewports, they will change to the default stacked layout.
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> <p>Sample text here...</p> </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.
Take the same <pre> element and add two optional classes for enhanced rendering.
<p>Sample text here...</p>
<pre class="prettyprint
linenums">
<p>Sample text here...</p>
</pre>

Bootstrap provides a lightweight, flexible component called a hero unit to showcase content on your site. It works well on marketing and content-heavy sites.
Wrap your content in a div like so:
<div class="hero-unit">
<h1>Heading</h1>
<p>Tagline</p>
<p>
<a class="btn btn-primary btn-large">
Learn more
</a>
</p>
</div>
This is a simple hero unit, a simple jumbotron-style component for calling extra attention to featured content or information.
By default, Bootstrap’s thumbnails are designed to showcase linked images with minimal required markup.
With a bit of extra markup, it’s possible to add any kind of HTML content like headings, paragraphs, or buttons into thumbnails.
Thumbnails (previously .media-grid up until v1.4) are great for grids of photos or videos, image search results, retail products, portfolios, and much more. They can be links or static content.
Thumbnail markup is simple—a ul with any number of li elements is all that is required. It’s also super flexible, allowing for any type of content with just a bit more markup to wrap your contents.
Lastly, the thumbnails component uses existing grid system classes—like .span2 or .span3—for control of thumbnail dimensions.
As mentioned previously, the required markup for thumbnails is light and straightforward. Here’s a look at the default setup for linked images:
<ul class="thumbnails">
<li class="span3">
<a href="#" class="thumbnail">
<img src="http://placehold.it/260x180" alt="">
</a>
</li>
...
</ul>
For custom HTML content in thumbnails, the markup changes slightly. To allow block level content anywhere, we swap the <a> for a <div> like so:
<ul class="thumbnails">
<li class="span3">
<div class="thumbnail">
<img src="http://placehold.it/260x180" alt="">
<h5>Thumbnail label</h5>
<p>Thumbnail caption right here...</p>
</div>
</li>
...
</ul>
Explore all your options with the various grid classes available to you. You can also mix and match different sizes.
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>.
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.
Bootstrap comes with a great jQuery plugin that supports alert messages, making dismissing them quick and easy.
Wrap your message and an optional close icon in a div with simple class.
<div class="alert"> <button class="close" data-dismiss="alert">×</button> <strong>Warning!</strong> Best check yo self, you're not looking too good. </div>
Heads up! iOS devices require an href="#" for the dismissal of alerts. Be sure to include it and the data attribute for anchor close icons. Alternatively, you may use a button element with the data attribute, which we have opted to do for our docs.
Easily extend the standard alert message with two optional classes: .alert-block for more padding and text controls and .alert-heading for a matching heading.
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.
<div class="alert alert-block"> <a class="close" data-dismiss="alert" href="#">×</a> <h4 class="alert-heading">Warning!</h4> Best check yo self, you're not... </div>
<div class="alert alert-error"> ... </div>
<div class="alert alert-success"> ... </div>
<div class="alert alert-info"> ... </div>
Use various of predefined dividers. For less padding use HR tag. For More padding use DIV tag.
<hr>
<hr class="divider1">
<div class="divider-title">...</div><hr class="divider1">
<div class="divider divider10"></div>
<div class="divider divider1"><span>...</span></div>
You can also use DIV with “closer” class to make less padding between elements. It will close up two elements with -30px margin bottom css.
Use the well as a simple effect on an element to give it an inset effect.
<div class="well">
...
</div>
Use the generic close icon for dismissing content like modals and alerts.
<button class="close">×</button>
iOS devices require an href=”#” for click events if you rather use an anchor.
<a class="close" href="#">×</a>
