布局：flex弹性布局_实践01（

一、等分：平均分布。在容器里面平均分配空间，需要设置项目的自动缩放。

section{
  display:-webkit-flex;
  display: flex;
}

article,aside {
  flex: 1;
  border:1px solid red;
}

<!doctype html>
<html>
<head>
    <meta charset="utf-8" />
    <title>H5标准页面</title>
    <link href="css/css实现树形图 - 副本 (2).css" rel="stylesheet" type="text/css" />
</head>

<body>
    <section>
        <article>…
        </article>

        <aside>…
        </aside>
    </section>

    <section>
        <article>…
        </article>

        <aside>…
        </aside>

        <aside>…
        </aside>
    </section>

    <section>
        <article>…
        </article>

        <aside>…
        </aside>

        <aside>…
        </aside>

        <aside>…
        </aside>
    </section>
</body>
</html

二、百分比布局：某个网格的宽度为固定的百分比，其余网格平均分配剩余的空间。

section{
  display:-webkit-flex;
  display: flex;
}

article,aside{border:1px solid red;}

.Grid-cell {
  flex: 1;
}

.Grid-cell.u-full {
  flex: 0 0 100%;
}

.Grid-cell.u-1of2 {
  flex: 0 0 50%;
}

.Grid-cell.u-1of3 {
  flex: 0 0 33.3333%;
}

.Grid-cell.u-1of4 {
  flex: 0 0 25%;
}

<!doctype html>
<html>

<head>
    <meta charset="utf-8" />
    <title>H5标准页面</title>
    <link href="css/css实现树形图 - 副本 (2).css" rel="stylesheet" type="text/css" />
</head>

<body>
    <section >
        <article class="Grid-cell u-1of2 ">
            1/2
        </article>

        <aside class="Grid-cell">
            auto
        </aside>

        <aside class="Grid-cell">
            auto
        </aside>
    </section>

    <section>
        <articla class="Grid-cell" >
            auto
        </article>

        <aside class="Grid-cell u-1of3" >
            1/3
        </aside>
    </section>

    <section>
        <aside class="Grid-cell u-1of4" >
            1/4
        </aside>

        <article class="Grid-cell" >
            auto
        </article>

        <aside class="Grid-cell u-1of3" >
            1/3
        </aside>

    </section>
</body>
