css网格的广场与flexbox

我正在尝试创建一个响应格子的方块.应调整广告尺寸以适应视口的宽度.更改视口高度时,方块不应调整大小.

我得到了如何调整每个Square的宽度,但是我不知道如何使元素平方,以及如何在视口宽度改变时缩放它们的高度.

在下面的小提琴的例子中,七个方格应该总是水平放置,并且它们应该以正方形缩放.我不在乎有多少行是可见的.

解决方法

你不应该设置任何大小.
您可以使用额外的元素或伪元素与垂直填充在％.这将允许您使用width作为参考：一个代码段来显示：

.flex-container {
    padding: 0;
    margin: 0;
    list-style: none;
    display: -webkit-Box;
    display: -moz-Box;
    display: -ms-flexBox;
    display: -webkit-flex;
    display: flex;
    -webkit-flex-flow: row;
    justify-content: space-around;
   
    line-height:30px;
}
.flex-item {
    background: tomato;
    margin: 5px;
    color: white;
    font-weight: bold;
    font-size: 1.5em;
    text-align: center;
    flex: 1 0 auto;
    height:auto;
}
.flex-item:before {
    content:'';
    float:left;
    padding-top:100%;
}

一个inline-block元素也可以做,只是适应框的显示/行为,它的内容.这里的魔法来自于填充：50％0; (100％垂直填充等于父母的宽度).参见w3c关于垂直margin和padding
