 ## Classes
 The standard way of creating classes in pdf.js is the following. Please note that by class we mean an object that is class-like.
-<pre>
+```
 var Name = (function NameClosure() {
   function Name(name) {
     this.name = name;
   }
 
   Name.prototype = {
+    ...
   };
-  ...
 
   return Name;
 })();
-</pre>
