对于如下代码，.box1 、.box2、.box3，真实宽度正确的是
<div class="container">
<div class="box box1"></div>
<div class="box box2"></div>
<div class="box box3"></div>
</div>
<style>
.container {
display: flex;
width: 200px;
height: 100px;
}
.box1 {
width: 100px;
flex-shrink: 2;
background: red;
}
.box2 {
width: 50px;
flex-shrink: 2;
background: blue;
}
.box3 {
width: 100px;
flex-shrink: 1;
background: pink;
}
</style>
计算方式:
父级宽200 子项目宽度为100+50+100=250
溢出:50
首先计算加上权重的值:200+100+100=400
100 * 2/400 * 50 =25 50 * 2/400 * 50 =12.5 100 * 1/400 * 50= 12.5
