--- id: 5d822fd413a79914d39e98dc title: Step 20 challengeType: 0 dashedName: step-20 --- # --description-- The buildings are stacked on top of each other and running off the screen. Let's fix that. Add the properties `display: flex;`, `align-items: flex-end;`, and `justify-content: space-evenly;` to the `background-buildings` class. This will use flexbox again to evenly space the buildings across the bottom of the element. # --hints-- You should add a `display` of `flex` to the `background-buildings` class. ```js assert.equal(new __helpers.CSSHelp(document).getStyle('.background-buildings')?.display, 'flex'); ``` You should add an `align-items` of `flex-end` to the `background-buildings` class. ```js assert.equal(new __helpers.CSSHelp(document).getStyle('.background-buildings')?.alignItems, 'flex-end'); ``` You should add a `justify-content` of `space-evenly` to the `background-buildings` class. ```js assert.equal(new __helpers.CSSHelp(document).getStyle('.background-buildings')?.justifyContent, 'space-evenly'); ``` # --seed-- ## --seed-contents-- ```html City Skyline
