首先上传图标到/ripro/assets/images，图标地址。然后修改/ripro/assets/css/diy.css,如下：

.vvip0,.vvip10,.vvip30,.vvip70,.vvip75,.vvip80,.vwip0,.vwip10,.vwip30,.vwip70,.vwip75,.vwip80,.vvip302,.vvip702,.vvip752,.vvip802,.vwip302,.vwip702,.vwip752,.vwip802 {
    display: inline-block;
    background-image: url(../images/tuyiyi_vip4_1.png);
    background-size: auto 40px;
    vertical-align: middle;
    height: 40px;
    width: 40px
}

.vvip0,.vvip10,.vvip30, .vvip70, .vvip75, .vvip80, .vvip302, .vvip702, .vvip752, .vvip802 {
    position: absolute;
    top: 0;
    left: 0;
    z-index: 10;
}


.vvip0,.vwip0 {
    background-position: 0 0
}

.vvip70,.vwip70 {
    background-position: -80px 0
}

.vvip30,.vwip30 {
    background-position: -40px 0
}

.vvip302,.vvip702,.vvip752,.vvip802 {
    background-position: -200px 0
}

.vvip75 {
    background-position: -160px 0
}

.vvip80,.vwip75,.vwip80 {
    background-position: -120px 0
}

.vwip0,.vwip10,.vwip30,.vwip70,.vwip75,.vwip80,.vwip302 {
    position: absolute;

    z-index: 10;
    border-radius: 5px 0 0 0
}

.vvip10,.vwip10 {
    background-position: 0 0
}

为什么这么多？因为图片里还有预制的几个备用图标，比如SVIP,QVIP之类的，可以自己选用！我这里只用了免费和VIP两个！

然后修改/ripro/parts/template-parts/content-grid.php第十行也就是在

<?php cao_entry_media( array( 'layout' => 'rect_300' ) ); ?> 

之前，

修改/ripro/parts/template-parts/content-list.php第八行也就是在

<?php cao_entry_media( array( 'layout' => 'rect_300' ) ); ?>

之前，

加上如下：

<?php if ((_get_post_shop_status() || _get_post_shop_hide()) && _cao('grid_is_price',true)) :
 $post_price = _get_post_price();
 $post_price =($post_price) ? '<i class="vwip30"></i>' : '<i class="vwip10"></i>' ;
 ?>
 <?php echo ''.$post_price;?>
 <?php endif; ?>

然后清空服务器和浏览器的缓存，查看首页效果，如果有位置偏移适当调整CSS即可。
