ブラウザの幅が５００px以下の時にハンバーガーメニューが開くように意図して作ったはずなのですが、５００px以下の時もハンバーガーメニューが開きません。<https://saruwakakun.com/html-
css/reference/nav-drawer> のサイトを参考にして作ったのですが。また、ハンバーガーメニューの中に `<ul
id="social">` の中身も入るようにしたいのに、今はその中身がハンバーガーメニューに入っていません。どのように修正すれば良いのでしょうか？

ハンバーガーメニューが開かない
チェックボックスにチェックが付いていない状態で、画面幅が 500px 以下のときにハンバーガーメニューを表示させたい、ということであれば、 `:not`
擬似クラスを用いてハンバーガーメニューが表示される条件を変更すれば良いと思います。

```

    @media all and (max-width: 500px) {
      #nav-input:not(:checked) ~ #nav-close {
        display: block;
        opacity: 0.5;
      }
      #nav-input:not(:checked) ~ #nav-content {
        -webkit-transform: translateX(0%);
        transform: translateX(0%);
        box-shadow: 6px 0 25px rgba(0, 0, 0, 0.15);
      }
    }
    
```

もしチェックボックスの値に関わらず、 500px 以下の画面幅のときにハンバーガーメニューを表示された状態にしたいのであれば、 JavaScript
を使う必要があります。

```

    let flag = false;
    
    window.addEventListener("resize", () => {
      const documentWidth = document.documentElement.getBoundingClientRect().width;
      const checkBox = document.getElementById("nav-input");
      if (flag === true) {
        if (documentWidth > 500) flag = false;
        return;
      }
    
      checkBox.checked = flag = true;
    }, false);
    
    document.addEventListener("DOMContentLoaded", () => {
      const e = document.createEvent("HTMLEvents");
      e.initEvent("resize", true, true);
      window.dispatchEvent(e);
    }, false);
    
```

```

    let flag = false;
    window.addEventListener("resize", () => {
      const documentWidth = document.documentElement.getBoundingClientRect().width;
      const checkBox = document.getElementById("nav-input");
      if (flag === true) {
        if (documentWidth > 500) flag = false;
        return;
      }
    
      checkBox.checked = flag = true;
    }, false);
    
    document.addEventListener("DOMContentLoaded", () => {
      const e = document.createEvent("HTMLEvents");
      e.initEvent("resize", true, true);
      window.dispatchEvent(e);

また、ハンバーガーメニューの中に`social`クラスを付与した`ul`要素が入っていない原因は、ハンバーガーメニューである`#nav-
