将 width 设置为 100% 并添加 min-width: 530px; 如果宽度不是，您的 .content 将缩放 小于 .box
.box {
width: 95%;
background-color: red;
padding: 20px;
text-align: center;
margin: 55px auto 40px;
}
.content {
display: inline-block;
text-align: center;
min-width: 530px;
width:100%;
height: 500px;
padding: 57px 40px 0;
background-color: #e9e9e9;
height: 800px;
box-sizing: border-box;
}<div class="box">
<div class="content">
