# --description--
Adding 1 pixel of padding to the top, bottom, left, and right of the canvas changed its dimensions to 502 pixels x 602 pixels.
Replace the `padding` property with `overflow` set to `hidden` - changing the canvas back to its original dimensions.
# --hints--
You should remove the `padding` property from the `.one` selector.
```js
const onePadding = new __helpers.CSSHelp(document).getStyle('.one').getPropertyValue('padding');
assert(!onePadding);
```
You should set the `overflow` property to `hidden`.
```js
const hasOverflow = new __helpers.CSSHelp(document).getCSSRules().some(x => x.style.overflow === 'hidden');
assert(hasOverflow);
```
Your `.canvas` element should have an `overflow` value of `hidden`.
```js
const canvasOverflow = new __helpers.CSSHelp(document).getStyle('.canvas')?.getPropertyValue('overflow');
assert(canvasOverflow === 'hidden')
```
