font-family: system-ui;
system-ui 将会自动选取系统默认字体作为字体，如 bootstrap 的样式规则 (opens new window)
$font-family-sans-serif: system-ui, -apple-system, "Segoe UI", Roboto, "Helvetica Neue",
Arial, "Noto Sans", "Liberation Sans", sans-serif, "Apple Color Emoji", "Segoe UI Emoji",
"Segoe UI Symbol", "Noto Color Emoji" !default;
