Kraken uses relative sizing (ems and %, not px) for everything.
The body has a base font-size of 106.25%, which is 17px on browsers with default font settings. All other sizes are in ems. Changing the font-size on the body element will adjust the typographical scale for the entire site.

The font-family on the body is "Helvetica Neue", Arial, sans-serif. This sets the typeface for the entire site. Adjust as needed.
The typographic scale was built using Iain Lamb's Typograph app.
Default text.
Muted text.

Bold and italics.
Note: Because Kraken uses relative sizing, you should always apply .text-tall and .text-small classes to a <span> element and not directly to a <p>. Otherwise, your spacing will get all messed up.
