# --description--

將 CSS 網格與使用媒體查詢結合使用，如使用媒體查詢重新排列網格區域、更改網格尺寸以及重新排列網格項位置，我們可以讓製作出的網站更具響應性。

在右側的預覽區中，當網頁可視區域的寬不小於 300px 時，列數從 1 變爲 2。 並且，廣告（advertisement）區域會完全佔據左列。

# --instructions--

當網頁可視區域的寬不小於 `400px` 時，請讓 header 區域完全佔據最頂行，footer 區域完全佔據最底行。

# --hints--

當網頁可視區域的寬度爲 `400px` 或以上時，class 爲 `container` 的元素應具有 `grid-template-areas` 屬性，其屬性值能夠使 footer 和 header 區域分別佔據頂行和底行，advert 和 content 區域分別佔據中間行的左列和右列。

```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
    )
);
```
