Body
<p>I've followed tutorials regarding creating a canvas, however it is not working and neither is the rectangle drawn on it. Is it a necessity to have the script in the <code><head></code>? Any help would be appreciated!</p> <p>Here's a <a href="http://jsfiddle.net/3Y8XV/" rel="nofollow">JSFiddle</a> with my code.</p> <pre><code><!DOCTYPE html> <html> <head> <title>Simple animations in HTML5</title> </head> <body> <h2> Optical Illusion </h2> <video id="illusion" width="640" height="480" controls> <source src="Illusion_movie.ogg"> </video> <div id="buttonbar"> <button onclick="changeSize()">Big/Small</button> </div> <p> Watch the animation for 1 minute, staring at the centre of the image. Then look at something else near you. For a few seconds everything will appear to distort. Source: <a href="http://en.wikipedia.org/wiki/File:Illusion_movie.ogg">Wikipedia:Illusion movie</a> </p> <script> var myVideo=document.getElementById("illusion"); var littleSize = false; function changeSize() { myVideo.width = littleSize ? 800 : 400; littleSize = !littleSize;//toggle boolean } </script> <canvas id= "myCanvas " width= "500 " height= "500 "> style="border:1px solid #000000;"> </canvas> <script> var canvas = document.getElementById("myCanvas"); var context = canvas.getContext("2d"); context.fillStyle = "blue"; context.fillRect(20, 50, 200, 100); </script> </body> </html> </code></pre>

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
