## Typography

The main branding typeface is [**Europa**](http://www.europatype.com/articledetail/17), used for both text and headline. Europa is only [available from Typekit](https://typekit.com/fonts/europa) or as a paid download. Please consult a designer to assist you in using this font in your documents & presentations.

<div class="typeface light">Europa Light</div>
<div class="typeface">Europa Regular</div>
<div class="typeface italic">Europa Regular Italic</div>
<div class="typeface bold">Europa Bold</div>

The light weight is only used for headlines from a certain size to retain readability on all screens. For the website this means only headings 1 - 4 are using light weight.
