リストなどのアイテムが無い時に「ありません」を表示させる

Last updated at Posted at 2020-03-05

頭にアイテムの無い時の状態を入れておいて、アイテムが追加されたらその表示だけにする。

html
<ul>
  <li>ありません</li>
  <li>アイテム1</li>
  <li>アイテム2</li>
  <li>アイテム3</li>
</li>
css
ul > li:first-child() {
  display: none;
}
ul > li:last-child() {
  display: inherit;
}

アイテム1,2,3があれば、

  • アイテム1
  • アイテム2
  • アイテム3

なければ、

  • ありません

という表示になる。
