Add this line inside your <head></head> section:

<link rel="stylesheet" type="text/css" href="news-07.css">

You will find the code for the news template in the file template.html. Copy and paste it where you want it on your website.



Note: 

If you want to display the icons in the .news-footer box, you will also need to upload the /fontawesome folder and add the icon font to your <head> area:

<link rel="stylesheet" type="text/css" href="fontawesome/font-awesome.all.min.css">
<link rel="stylesheet" type="text/css" href="news-07.css">

(Unless, of course, you already use Font Awesome and have already included the font.)
