--- id: 5d822fd413a79914d39e98e5 title: Step 29 challengeType: 0 dashedName: step-29 --- # --description-- You want the foreground buildings container to sit directly on top of the background buildings element. Give it a `width` and `height` of `100%`, set the `position` to `absolute`, and the `top` to `0`. This will make it the same size as the body and move the start of it to the top left corner. # --hints-- You should use a `.foreground-buildings` selector. ```js assert.exists(new __helpers.CSSHelp(document).getStyle('.foreground-buildings')); ``` You should give the `.foreground-buildings` element a `width` of `100%`. ```js assert.equal(new __helpers.CSSHelp(document).getStyle('.foreground-buildings')?.width, '100%'); ``` You should give the `.foreground-buildings` element a `height` of `100%`. ```js assert.equal(new __helpers.CSSHelp(document).getStyle('.foreground-buildings')?.height, '100%'); ``` You should give the `.foreground-buildings` element a `position` of `absolute`. ```js assert.equal(new __helpers.CSSHelp(document).getStyle('.foreground-buildings')?.position, 'absolute'); ``` You should give the `.foreground-buildings` element a `top` of `0`. ```js assert.equal(new __helpers.CSSHelp(document).getStyle('.foreground-buildings')?.top, '0px'); ``` # --seed-- ## --seed-contents-- ```html City Skyline
