    <p>All you have to do is create one or more radial gradients to fit the properties of the glassy object that you want. It's easy to do!</p> <p>Just one gradient:</p> <pre><code>// Create some gradient var gradient = ctx.createRadialGradient(105, 105, 20, 120, 120, 50); gradient.addColorStop(0, 'rgba(250,250,255,0)'); gradient.addColorStop(0.75, 'rgba(230,250,255,1.0)'); gradient.addColorStop(1, 'rgba(0,0,255,0)'); // draw the gradient (note that we dont bother drawing a circle, this is more efficient and less work!) // but make sure it covers the entire gradient ctx.fillStyle = gradient; ctx.fillRect(0, 0, 300, 300);​ </code></pre> <p>Can make this:</p> <p><img src="https://i.stack.imgur.com/4uzKp.png" alt="enter image description here"></p> <p>Live example:</p> <p><a href="http://jsfiddle.net/GTbjk/" rel="noreferrer">http://jsfiddle.net/GTbjk/</a></p> <p>Maybe you want to reign in that fuzzy edge:</p> <pre><code>gradient.addColorStop(0.8, 'rgba(0,0,255,0)'); gradient.addColorStop(1, 'rgba(0,0,255,0)'); </code></pre> <p><a href="http://jsfiddle.net/GTbjk/1/" rel="noreferrer">http://jsfiddle.net/GTbjk/1/</a></p> <p>I'm not going to make one to your specification, since you didn't provide one and thats not what we're here for anyway. Making these will almost exclusively be the work of well-placed radial gradients, so go experiment!</p> <p>As j08691 points out this is a really inefficent way of making these unless you want them to be dynamic or scalable, you are better off just making images and use <code>ctx.drawImage</code></p>

    1. COSimon, This is very visually appealing. I really need to get a book on computer graphics because you made this look so nice with so little code. As I mentioned in my comment above, my original plan was to allow flexibility in color selection, but maybe that's not necessary and I should just build a collection of 20 or so .PNG files and reference those. Thanks again, Simon!

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.
