html - css表在页面上没有响应

Question

我的网站上有一张桌子，里面有产品卡片，效果很好，但在手机上，它没有显示为响应式。这是链接：Marcos-backyard-swimming.herokuapp.com/#work

表格（在移动设备上）似乎溢出了该页面的宽度，而在计算机上则非常好......不知道为什么，但这是代码

我的表格代码如下：

  @media screen and (min-width: 600px) {
  .product-card {
    width: 380px;
    position: relative;
    box-shadow: 0 2px 7px #dfdfdf;
    margin: 5px auto;
    background: #fafafa;
} 
}
@media screen and (max-width: 600px) {
  .product-card {
    width: 280px;
    position: relative;
    box-shadow: 0 2px 7px #dfdfdf;
    margin: 5px auto;
    background: #fafafa;
} 
}
.badge {

.product-price small {

    font-weight: 400;
    text-decoration: line-through;
    display: inline-block;
    margin-right: 5px;
}

.product-links {
    text-align: right;
}

.product-links a {
