587d7788367417b2b2512aa2	使用 nav 元素使屏幕閱讀器更容易導航	0	https://scrimba.com/c/czVwWSv	301024	make-screen-reader-navigation-easier-with-the-nav-landmark

--description--

nav 也是一個具有語義化特性的 HTML5 標籤，它可以使屏幕閱讀器快速識別出頁面中的導航信息。它用於呈現頁面中的主導航鏈接。

對於在多個頁面底部出現的站點鏈接，我們不需要使用 nav 標籤。我們將會在下個挑戰中學習 footer 標籤的使用。

--instructions--

Camper Cat 在他的忍者訓練頁面頂端放置了多個導航鏈接，但這些鏈接都寫在了 div 中。請將 div 標籤更改爲 nav 標籤，以提升頁面的可訪問性。

--hints--

應存在一個 nav 標籤。

assert($('nav').length == 1);

nav 標籤應包含 ul 標籤及其列表項。

assert($('nav').children('ul').length == 1);

不應存在 div 標籤。

assert($('div').length == 0);

確保 nav 標籤是閉合的。

assert(
  code.match(/<\/nav>/g) &&
    code.match(/<\/nav>/g).length === code.match(/<nav>/g).length
);
