我刚刚使用旧技术（浮动元素和嵌入式元素）创建了一个网格布局。它足够好用。简要地说，我有一个顶级包装器类来居中和限制大小内容。有2个主要部分，每个部分都有标题（20％），其余部分（80％）以不同的方式细分。甚至还有一个设置有填充物的弹性排水沟（在em中）。我在设计布局时考虑到了内容与表示之间的良好分隔，以实现较高的代码可维护性，并且在这种情况下，存在一些多余的标记（尤其是div）。
代码如下：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Float layout plus wrapping rows using inline-block</title>
<!-- the base styles and "housekeeping" styles are in here: -->
<link rel="stylesheet" href="css/grid-base.css">
<!-- the HTML5 shiv,to help older browsers understand styling
on newer HTML5 elements: -->
<script src="js/html5shiv.min.js"></script>
<style>

为改进我稍后介绍的代码（一种渐进式增强），flexbox的功能，在等高的盒子中添加一些装饰，这是float所具有的一项棘手的功能（实际上，已经有导航栏的flexbox，带有类似后备浮动的float）。
我正在使用Modernizr来测试特定的flexbox支持（flexbox和flexwrap类）。我在Firefox中取得了惊人的成绩（由于我的有限经验），但是令我惊讶的是，当我在Google Chrome浏览器中测试代码时，出现了一个视觉错误：第一部分的第二个嵌套行与第一行重叠，能够理解为什么。
这是代码： https://jsfiddle.net/rs7n8hLm/
您可以在jsfiddle浏览器中看到相同的问题。 建议也受到赞赏，因为我在一条小巷里，如果某些代码行晦涩难懂，我非常有空。 预先感谢。
