Now target your #piano element with an id selector. Set background-color property to #00471b, the width property to 992px and the height property to 290px.

--hints--

You should have a #piano selector.

js
assert(new __helpers.CSSHelp(document).getStyle('#piano'));

Your #piano selector should have the background-color property set to #00471b.

js
assert(new __helpers.CSSHelp(document).getStyle('#piano')?.backgroundColor === 'rgb(0, 71, 27)');

Your #piano selector should have a width property set to 992px.

js
assert(new __helpers.CSSHelp(document).getStyle('#piano')?.width === '992px');

Your #piano selector should have the height set to 290px.

js
assert(new __helpers.CSSHelp(document).getStyle('#piano')?.height === '290px');
