One dash of the net

What we are doing

The net in the middle is a dashed line. We draw its first dash: a white rectangle 4 pixels wide and 15 tall, centered on the middle of the court.

```js
ctx.fillStyle = 'white'
ctx.fillRect(canvas.width / 2 - 2, 0, 4, 15)
```

What it means

• canvas.width / 2 is the middle (300); - 2 centers a 4 pixel wide dash on it.
• 0 is the top; the dash is 15 pixels tall.

Your turn

At the very end, leave an empty line and write the two white lines. Press Run.
