 ## Steps to Simulate Kiosk Mode
 
 ### Step 1
 
 Compile the following Java code:
 
-```
+```java
 import java.awt.*;
 import java.applet.*;
 import java.security.*;
 import java.awt.event.*;
 
 public class FullScreen extends Applet
 {
    public void fullScreen()
    {
       AccessController.doPrivileged
       (
-         new PrivilegedAction() 
+         new PrivilegedAction()
          {
-            public Object run() 
+            public Object run()
             {
                try
                {
                   Robot robot = new Robot();
                   robot.keyPress(KeyEvent.VK_F11);
                }
                catch (AWTException e)
                {
                   e.printStackTrace();
                }
                return null;
             }
          }
       );
    }
 }
 ```
 
 ### Step 2
 
 Include it in an applet on your kiosk application's home page:
 
-```
-<applet name="appletFullScreen" code="FullScreen.class" width="1" height="1"></applet>
+```html
+<applet name="appletFullScreen"
+        code="FullScreen.class"
+        width="1"
+        height="1"></applet>
 ```
 
 ### Step 3
 
 Add the following to the kiosk computer's java.policy file:
 
 ```
 grant codeBase "http://yourservername/*"
-{ 
+{
    permission java.security.AllPermission;
 };
 ```
 
 ### Step 4
 
-Include the following JavaScript and assign the doLoad function to the onload event:
+Include the following JavaScript and assign the `doLoad` function to the
+`onload` event:
 
-```
+```javascript
 var _appletFullScreen;
 
 function doLoad()
 {
    _appletFullScreen = document.applets[0];
    doFullScreen();
 }
 
 function doFullScreen()
 {
    if (_appletFullScreen && _appletFullScreen.fullScreen)
    {
-// Add an if statement to check whether document.body.clientHeight is not indicative of full screen mode
+      // Add an if statement to check whether document.body.clientHeight is not
+      // indicative of full screen mode
       _appletFullScreen.fullScreen();
    }
 }
-```
