# --description--
CSS Grid can be an easy way to make your site more responsive by using media queries to rearrange grid areas, change dimensions of a grid, and rearrange the placement of items.
In the preview, when the viewport width is 300px or more, the number of columns changes from 1 to 2. The advertisement area then occupies the left column completely.
# --instructions--
When the viewport width is `400px` or more, make the header area occupy the top row completely and the footer area occupy the bottom row completely.
# --hints--
When the viewport is `400px` or more, `container` class should have a `grid-template-areas` property in which the header and footer areas occupy the top and bottom rows respectively and advert and content occupy the left and right columns of the middle row.
```js
assert(
__helpers
.removeCssComments(code)
.match(
/@media\s*?\(\s*?min-width\s*?:\s*?400px\s*?\)[\s\S]*.container\s*?{[\s\S]*grid-template-areas\s*?:\s*?"\s*?header\s*?header\s*?"\s*?"\s*?advert\s*?content\s*?"\s*?"\s*?footer\s*?footer\s*?"\s*?;[\s\S]*}/gi
)
);
```
