/* 首页新版 v3(components/index-v3/)
   第一段照搬小样 ~/my/content/seo/product-pages/home/proto/home.html 的样式,全部收在 .hv3 下面,关键帧加 hv3- 前缀;
   小样里没用到的规则和导航占位已去掉。
   本目录是 static/css/index-v3.css 的源文件,按文件名顺序拼接:10 小样照搬、20 功能墙、30 上手屏浅色、40 落地补充、50 手机和平板适配。
   改样式改这里,再跑 node scripts/build-css.js 生成(会自动补老浏览器兼容);别直接改 static/css/index-v3.css。 */
