黑体

font-family: -apple-system, 'Helvetica Neue', Helvetica, 'Nimbus Sans L', Arial, 'Liberation Sans', 'PingFang SC', 'Hiragino Sans GB',
  'Source Han Sans CN', 'Source Han Sans SC', 'Microsoft YaHei', 'Wenquanyi Micro Hei', 'WenQuanYi Zen Hei', 'ST Heiti', SimHei,
  'WenQuanYi Zen Hei Sharp', sans-serif;

Use apple system font (like San Francisco) by default, see also: https://github.com/zenozeng/fonts.css/issues/29
某些 Linux 中 Helvetica 会自动 fallback 到 Nimbus Sans L （具体见 /etc/fonts/conf.d/30-metric-aliases.conf, debian jessie/sid ）
某些 Linux 中 Arial 会自动 fallback 到 Liberation Sans （具体见 /etc/fonts/conf.d/30-metric-aliases.conf, debian jessie/sid ）
