Now `.one` is centered horizontally, but its top margin is pushing past the canvas and onto the frame's border, shifting the entire canvas down 20 pixels.
Add `padding: 1px;` to `.canvas` to give the `.one` element something solid to push off of.
# --hints--
You should set the `padding` property to `1px`.
```js
const hasPadding = new __helpers.CSSHelp(document).getCSSRules().some(x => x.style.padding === '1px');
assert(hasPadding);
```
Your `.canvas` element should have a `padding` value of `1px`.
```js
const canvasPadding = new __helpers.CSSHelp(document).getStyle('.canvas')?.getPropertyValue('padding');
