问题描述
我正在尝试使用div创建2x2网格.某些div可能包含图像,但可能会将其设置为背景,并带有background-size: cover
选项.
I'm trying to create a 2x2 grid with divs. Some of the divs might contain an image, but it will probably be set as a background, with the option background-size: cover
.
这是我创建的笔: http://codepen.io/qarlo/pen/vLEprq
.container {
display: flex;
flex-wrap: wrap;
justify-content: space-between;
margin: auto;
max-width: 960px;
width: 80%;
}
.container__item {
align-content: center;
border: 1px solid #333;
display: flex;
flex-basis: 1;
font-size: 3em;
justify-content: center;
height: 100%;
margin-bottom: 1em;
min-height: 300px;
width: 47%;
}
<div class="container">
<div class="container__item">?</div>
<div class="container__item">?</div>
<div class="container__item">?</div>
<div class="container__item">?</div>
</div>
在调整大小时,我想强制将div设为正方形并保持宽高比.我错误地希望Flexbox能够做到这一点很简单,但是除非我丢失了某些东西,否则我是错的.
I'd like to force the divs to be squares and maintain the aspect ratio when resizing it. I was mistakenly hoping that this would have been straightforward with flexbox, but unless I'm missing something, I was wrong.
推荐答案
要保持商品的长宽比,一种非常简单的方法是使用 CSS视口单位
To maintain your items aspect ratio, a very simple method is to use CSS Viewport units
我修改了您的笔以查看其工作原理: http://codepen.io/vladbicu/pen/wMBmOb
I modified your pen to see how this units work: http://codepen.io/vladbicu/pen/wMBmOb
.container {
display: flex;
flex-wrap: wrap;
justify-content: space-between;
margin: auto;
max-width: 960px;
width: 80%;
}
.container__item {
align-content: center;
border: 1px solid #333;
display: flex;
flex-basis: 1;
font-size: 3em;
justify-content: center;
margin-bottom: 1em;
// maintain aspect ratio
width: 30vw;
height: 30vw;
}
