Give the `.fb4-window` elements a `width` of `30%`, `height` of `10%`, and `border-radius` of `50%`. These will make some circular windows for this building.

assert.equal(new __helpers.CSSHelp(document).getStyle(".fb4-window")?.width, "30%");

assert.equal(new __helpers.CSSHelp(document).getStyle(".fb4-window")?.height, "10%");
