## Description
|
|
<section id='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.
|
|
</section>
|
|
|
|
## Instructions
|
|
<section id='instructions'>
|
|
When the viewport width is <code>400px</code> or more, make the header area occupy the top row completely and the footer area occupy the bottom row completely.
|
|
</section>
|
|
|

## Tests
|
|
<section id='tests'>
|
|
|
|
```yml
|
|
tests:
|
|
- text: When the viewport is <code>400px</code> or more, <code>container</code> class should have a <code>grid-template-areas</code> property in which the footer and header areas occupy the top and bottom rows respectively and advert and content occupy the left and right columns of the middle row.
|
|
testString: assert(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), 'When the viewport is <code>400px</code> or more, <code>container</code> class should have a <code>grid-template-areas</code> property in which the footer and header areas occupy the top and bottom rows respectively and advert and content occupy the left and right columns of the middle row.');
