--description--

Time to style the keys themselves. Create a class selector for the .key elements. Set the background-color set to the value #ffffff, the position property to relative, the width property to 41px, and the height property to 175px.

--hints--

You should have a .key selector.

assert(new __helpers.CSSHelp(document).getStyle('.key'));

Your .key selector should have a background-color property set to #ffffff.

assert(new __helpers.CSSHelp(document).getStyle('.key')?.backgroundColor === 'rgb(255, 255, 255)');

Your .key selector should have the position property set to relative.

assert(new __helpers.CSSHelp(document).getStyle('.key')?.position === 'relative');

Your .key selector should have a width property set to 41px.

assert(new __helpers.CSSHelp(document).getStyle('.key')?.width === '41px');

Your .key selector should have a height property set to 175px.

assert(new __helpers.CSSHelp(document).getStyle('.key')?.height === '175px');
