CSS と流動グリッドは初めてです。ここでこのチュートリアルに従っています:
http://www.1stwebdesigner.com/tutorials/fluid-grids-in-responsive-design/
そこで読んだ提案に従って、cssファイルを自動生成しました。各部分が画面幅の 1/3 を占める 3 つの部分からなるヘッダーを作成したかったのです。ただし、次のように、コンテンツに合わせて div の幅が縮小されているようです。
div を 33% まで満たすようにするにはどうすればよいですか?
HTMLは次のとおりです。
<html>
<head>
<title>Page Title</title>
<link href="testcss.css" rel="stylesheet" type="text/css">
</head>
<body>
<div class="containter_12">
<div class="grid_4">
<img src="logo.png"/>
</div>
<div class="grid_4">
<b>ACPL Wellness</b>
</div>
<div class="grid_4">
<b>Home</b>
</div>
</div>
</body>
</html>
CSS は次のとおりです。
