--description--

Use margins to position the .one element on the canvas.

Add the shorthand margin: 20px auto; to set the top and bottom margins to 20 pixels, and center it horizontally.

--hints--

You should set the margin property to 20px auto.

const marginFilter = new __helpers.CSSHelp(document).getCSSRules().filter(x => x.style.margin === '20px auto');
assert(marginFilter.length === 2);

Your .one element should have a margin value of 20px auto.

const oneMargin = new __helpers.CSSHelp(document).getStyle('.one')?.getPropertyValue('margin');
assert(oneMargin === '20px auto');
