HTML and CSS Reference
In-Depth Information
Application users don't want to spend their first 10 minutes randomly smashing keys and
clicking everywhere. Put your game's controls in an easy-to-find location and use concise
wording. For instance, placing the controls directly under a game is a great way to help
Step 4: Add control info via HTML
To add a control description to Canvas Ricochet, add a simple <p> tag directly below
<canvas> . It should say, “LEFT and RIGHT arrow keys or MOUSE to move.” If you
really want, you could create a graphical illustration that's easier to see, but for now you'll
just use text for simplicity.
<canvas id = "canvas" width = "408" height = "250" >
Your browser shall not pass! Download Google Chrome to view this.
<p> LEFT and RIGHT arrow keys or MOUSE to move </p>
<script type = "text/javascript" src = "game.js" ></script>
Congratulations! You've just completed an HTML5 game from beginning to end. You can
now play a complete level of Canvas Ricochet without interruption. We know it's been a
difficult journey to get this far, but why not take your game farther? With just a little more
work, you can add progressive level enhancement and screens to make your game shine.

dictive elements such as scoreboards, increased difficulty levels, and an enjoyable user ex-
perience are essential. They help to increase game revenue, maximize the number of users,
and, most important, keep people playing.
