Solution

font-family: fantasy does not load a specific font, fantasy is a special keyword (the other four being serif, sans-serif, monospace, and cursive) that tells the browser to load "any font that is in the fantasy category". You are guaranteed that by using it, different computers may load different fonts. If you want to load a specific font, using a webfont is the only real way to ensure all browsers, on all systems, load the same font.
