我正在创建一个Bootstrap网站，但是我已经遇到了一个问题，即使使用最简单的HTML也无法解决这个问题（这个问题是网站上唯一的元素）...我感到绝望：
<!DOCTYPE html>
<html lang="fr">
<head>
<meta charset="UTF-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Association Capucine - Gagner contre la leucémie</title>
</head>
<body>
<div class="d-flex justify-content-around">
<div class="p-2 bg-info">Flex item 1</div>
<div class="p-2 bg-warning">Flex item 2</div>
<div class="p-2 bg-primary">Flex item 3</div>
</div>
<main>
</main>
<footer>
</footer>
</body>
</html>
提前感谢
您需要包含Bootstrap CSS和Bootstrap JS。
请参见下面的代码片段。
