TailwindCSS 3
Chrome

はじめに

基本的に

具体的なサイズ（100%,100px,100remなど）を指定しなくて、自動幅調整を指定
FlexとGridを中心

ベースHTML

必要なタブ、とてもきれいなスタイルを追加

<!--index.html--> 

<!DOCTYPE html>
<html lang="ja">
  <head>
    <meta charset="UTF-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <link rel="stylesheet" href="/main.css" />
    <title>Tailwindcss Layout</title>
  </head>

  <!--body--> 
　<body class="font-bold text-gray-700">
    <div class="bg-cyan-100 pl-2">header</div>
    <div class="bg-yellow-100 pl-2">content</div>
    <div class="bg-purple-100 pl-2">footer</div>
  </body>
</html>

ベースCSS

html,body要素の高さを指定

/*main.css*/
@tailwind base;
@tailwind components;
@tailwind utilities;

@layer base {
    html,body {
        /*ニーズによって指定、ここはフル画面*/
        @apply min-h-screen;
    }
}

CodePenを使う場合

/* <script src="https://cdn.tailwindcss.com"></script> */
html,
body {
	min-height: 100vh;
}
