ブートストラップ4-ポップオーバー

説明

Popoverはツールチップに似ており、見出し付きの拡張ビューを提供します。 ポップオーバーをアクティブにするには、ユーザーは要素をクリックするだけです。

基本的なポップオーバー

_data-toggle = "popover" _属性を使用してポップオーバーを作成し、_data-content_属性を使用してポップオーバーにコンテンツを提供できます。

次の例は、基本的なポップオーバーを示しています-

例

<html lang = "en">
   <head>
      <!-- Meta tags -->
      <meta charset = "utf-8">
      <meta name = "viewport" content = "width = device-width, initial-scale = 1, shrink-to-fit = no">

      <!-- Bootstrap CSS -->
