小计一下border-img 和border-radius不兼容的解决办法
下面展示一些 内联代码片。

.ph-code>div {
    width: 208px;
    height: 80px;
    border: 2px solid transparent;
    background: linear-gradient(0deg, #FFE0CF, #FFF0DC);
    margin-left: 26px;
    font-size: 30px;
    line-height: 80px;
    position: relative;
    border-radius: 12px;
    background-clip: padding-box;
}
.ph-code>div::after {
    content: '';
    display: block;
    position: absolute;
    top: -2px;
    right: -2px;
    bottom: -2px;
    left: -2px;
    border-radius: 12px;
    background: linear-gradient(to right, #FFCC00, #FF9966);
    z-index: -1;
}
