The page editor allows you to assign custom classes/styles to elements in the content area.

There are several custom button options for your site.  You can highlight text in your content area, select the link icon to assign a link and then choose the button class from the formats menu.  The class must be assigned to the link.  The options are button-small, .button-medium and .button-large.  The style guide page displays each of these.

You can display a custom callout area on a page by wrapping content in a div tag with a class "div-callout".  This will present that content block with a dark background.

Example HTML:

<div class="div-callout">

<h3>Call to Action</h3>

<p>Atque haec couod cum accidisset ut alter alterum necopinato videremus. Moriatur, inquit. Deinde etiam cum mediocri amico.</p>

<p><a href="#" class="button-large">Large Button</a></p>

</div>
