If you meant the font choice for the general text of the website, than that's just whatever default font your web browser has chosen. In essence this website's code has not designated any font choice. So, whenever web browsers are not directed to use a certain font/typeface, they defer to their default font - usually some default system font. This has been the practice of web browsers since the very beginning of the web. As an example, for me on a windows 7 machine using chrome, it displays the font as Times New Roman; other browsers and OS combo might show different system fonts. I hope this helps!
