html - 无滚动条的响应式 3*3 方形 div 网格

Question

我想要一个没有滚动条的响应式 9x9 div 网格。 div 网格应根据可见的浏览器窗口调整大小。我合并了"How to maintain the aspect ratio of a div using only CSS"与 "Grid of responsive squares" :

CSS

@import url(http://fonts.googleapis.com/css?family=Lato:400,900);  /* <-- Just for the demo, Yes I like pretty fonts... */

.square {
    float:left;
    position: relative;
    width: 30%;
    padding-bottom : 30%; /* = width for a 1:1 aspect ratio */
    margin:1.66%;
    background-color:#1E1E1E;
    overflow:hidden;
}

.content {
    position:absolute;
    height:90%; /* = 100% - 2*5% padding */
    width:90%; /* = 100% - 2*5% padding */
    padding: 5%;

}
.table{
    display:table;
    width:100%;
    height:100%;
}

body {
    font-size:20px;
    font-family: 'Lato',verdana, sans-serif;
    color: #fff;
    text-align:center;
    background:#ECECEC;
}

.numbers{
    font-weight:900;
    font-size:100px;
}

div.stretchy-wrapper {
    width: 100%;
    padding-bottom: 56.25%; /* 16:9 */
    position: relative;

    background: lightgrey;
}

div.stretchy-wrapper > .inner {
    position: absolute;
    top: 0; bottom: 0; left: 0; right: 0;

    color: white;
    font-size: 24px;
    text-align: center;
}

然而，div 仍然会扩展到最大宽度，这会导致滚动条:Fiddle .

div 仅扩展到最大可见宽度或高度的 css 技巧是什么？所以我看不到滚动条？

用 Flexbox 和 vmin 解决了

CSS

    .container {
        margin: 0 auto;
        display: flex;
        flex-direction: row;
        flex-wrap: wrap;
        justify-content: space-around;
        align-items: center;
        align-content: space-around;

        height: 93vmin;
        width: 93vmin;
        background: lightgrey;
    }
    .cell {
        height: 30vmin;
        width: 30vmin;
        background-color:#1E1E1E;
    }

html

<div class="container">
    <div class="cell"></div>
    <div class="cell"></div>
    <div class="cell"></div>

    <div class="cell"></div>
    <div class="cell"></div>
    <div class="cell"></div>

    <div class="cell"></div>
    <div class="cell"></div>
    <div class="cell"></div>
</div>
