css3的选择器root a[href^=""] 有什么用！！,第1张

root a[href^="abc"] 匹配链接地址以abc开头的a标签

你这边截图的代码应该是用打包工具生成的，源码可能是用了某种css预处理器(less或scss)写的，有这么多网址显然是因为写这个样式的人没有编程思维，代码写的太差了

首先，ssh登录Y1S后台，修改opkg包管理器配置文件

mv /etc/opkg.conf /etc/opkg.conf.orig

cat >/etc/opkg.conf <<EOF

dest root /

dest ram /tmp

lists_dir ext /var/opkg-lists

option overlay_root /overlay
