响应式 Square Divs 跨浏览器兼容
[英] Responsive Square Divs Cross Browser Compatible
本文介绍了响应式 Square Divs 跨浏览器兼容的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我有一个 50/50 宽的页面.左半边有一排有六个 div.标准:
- 6 个方格必须始终保持方格.
- 前 5 个方格应该在右侧有边距/填充以进行分隔.
- 所有六个方格必须保持在同一行.如果我能做到这一点，我就可以在较小的视口中对响应能力进行必要的调整.
- 跨浏览器兼容最新版本的 ie、chrome 和 firefox.
我的代码笔:
<div class="容器"><div class="column" style="margin-right: 20px"><div class="flex-container"><div class="flex-item"><div class="flex-item-inner"><div class="flex-item-inner-content">L1
<div class="flex-item"><div class="flex-item-inner"><div class="flex-item-inner-content">L2

解决方案
这里的主要技巧是将 div 变成一个正方形.
通常设置一个 width，height 为 0 和一个 padding 等于 宽度
.square {高度:0；宽度:33%；填充底部:33%；背景:浅灰色；}
<div>内容
现在，当我们添加 display: flex 时，我们不能将 padding 与百分比一起使用(Firefox 错误)，我们也不能将高度与百分比一起使用，因为我们使用了高度:0.
为了克服这些问题，当可以使用视口单位 vw 代替时，我们也可以使用 height 而不是 padding 来保持它平方.
所以，不是像这样设置宽度，calc((100%/6) - 10px);，为了用大约 10px 宽的装订线平均分布 6 个项目，我们使用这样的视口单位calc(((50vw - 65px)/6) - 10px);
50vw 是浏览器宽度的一半，65px 是 container 的左/右填充之和，50px，加上 columns 之间的 15px 间距.
这也允许我们跳过额外的 flex-item-inner 元素，跳过在 content 元素上使用 position: absolute 和，因为我们没有在 flex-item 上使用百分比作为高度，我们可以这样做来使内容居中
.flex-item-content {高度:100%；显示:弹性；对齐内容:居中；对齐项目:居中；}

最后的结果是这样的

I have a page that is 50/50 wide. The left half has a row with six divs.
Criteria:
- 6 squares must always remain square.
- First 5 squares should have margin/padding to right for separation.
- All six squares must stay on same single row. If I can get that to work i can make the needed adjustments for responsiveness in smaller viewports.
- Cross browser compatible for newest version of ie, chrome, and firefox.

解决方案
The main trick here is to make the div a square.
Normally one set a width, the height to 0 and a padding that equals to the width
.square {
height: 0;
width: 33%;
padding-bottom: 33%;
background: lightgray;
}
<div class="square">
<div>
Content
</div>
</div>
Now, when we add display: flex, we can't use padding with percent (Firefox bug) and we can't use height with percent since we used height: 0.
To overcome these issues when can use viewport units vw instead, and with that we can also use height instead of padding to keep it squared.
So instead of setting a width like this, calc((100% / 6) - 10px);, to spread 6 items equally with a gutter about 10px wide, we use viewport units like this calc(( (50vw - 65px) / 6) - 10px);
The 50vw is half the browser width, the 65px is the sum of the container's left/right padding, 50px, plus the 15px gutter between the columns.
This also allows us to skip the extra flex-item-inner element, skip using position: absolute on the content element, and, as we didn't use percent for the height on the flex-item, we can do like this to center the content
.flex-item-content {
height: 100%;
display: flex;
justify-content: center;
align-items: center;
}
And the end result is this
