How to get web fonts working correctly in your server environment.

If you have web fonts on a subdomain seperate to the domain you are calling them, usual advice is to place the following into the .htaccess file for the subdomain

<IfModule mod_headers.c>
  <FilesMatch “.(eot|otf|ttc|ttf|woff|woff2)$”>
    Header set Access-Control-Allow-Origin “*”
  </FilesMatch>  
</IfModule>

How to pass data to partials in Handlebars.php

How to pass data to partials in Handlebars.php

The way data is passed in partials in salesforce/handlebars-php isn't the same as it is over at handlebars.js

Inspired by this issue

In this gist, we have a dataset of names that we want to display on a page. We are using a partial to format the display of the names to avoid writing repetitive code.
