Workshop › Flappy-style Bird › Step 2 of 30

Paint the sky

What we are doing

Our first drawing: the whole canvas becomes a light sky blue. Drawing is always two moves: pick a color, then fill a shape with it.

```js
ctx.fillStyle = '#70c5ce'
ctx.fillRect(0, 0, canvas.width, canvas.height)
```

What it means

• ctx.fillStyle = '#70c5ce' picks the fill color, a sky blue.
• ctx.fillRect(x, y, width, height) fills a rectangle. 0, 0 is the top-left corner, and canvas.width and canvas.height (400 and 600) make it cover everything.

Your turn

Leave an empty line under const ctx = ..., write the two lines, then press Run.
