# --description--
You can see the body, it's the horizontal line on your page; the box around it is the html element. Make your body fill the whole viewport by giving it a `height` of `100vh`. Remove the default margin from the body by setting the `margin` to `0`. Finally, set the `overflow` property to `hidden` to hide any scroll bars that appear when something extends past the viewport.
# --hints--
test-text
```js
const body = code.match(/body\s*{[\s\S]+?[^}]}/g)[0];
assert(
/height\s*:\s*100vh\s*(;|})/g.test(body) &&
/margin\s*:\s*(0|0px)\s*(;|})/g.test(body) &&
/overflow\s*:\s*hidden\s*(;|})/g.test(body)
);
```
