The frame is much too wide.

In .frame, set its width to 500 pixels.

--hints--

You should set the width property to 500px.

const widthFilter = new __helpers.CSSHelp(document).getCSSRules().filter(x => x.style.width === '500px');
assert(widthFilter.length === 2);

Your .frame element should have a width of 500px.

const frameWidth = new __helpers.CSSHelp(document).getStyle('.frame')?.getPropertyValue('width');
assert(frameWidth === '500px');
