Я использую mixin например...
@include font-face('Circe', '/template/fonts/Circe-Regular', normal, normal, woff2 woff ttf eot svg);
@include font-face('Circe', '/template/fonts/Circe-Light', 300, normal, woff2 woff ttf eot svg);
@include font-face('Circe', '/template/fonts/Circe-ExtraLight', 200, normal, woff2 woff ttf eot svg);
@include font-face('Circe', '/template/fonts/Circe-Thin', 100, normal, woff2 woff ttf eot svg);
Mixin ->@function str-replace($string, $search, $replace: "") {
$index: str-index($string, $search);
@if $index {
@return str-slice($string, 1, $index - 1) + $replace + str-replace(str-slice($string, $index + str-length($search)), $search, $replace);
}
@return $string;
}
@mixin font-face($name, $path, $weight: null, $style: null, $exts: eot woff2 woff ttf svg) {
$src: null;
$extmods: (
eot: "?",
svg: "#" + str-replace($name, " ", "_")
);
$formats: (
otf: "opentype",
ttf: "truetype"
);
@each $ext in $exts {
$extmod: if(map-has-key($extmods, $ext), $ext + map-get($extmods, $ext), $ext);
$format: if(map-has-key($formats, $ext), map-get($formats, $ext), $ext);
$src: append($src, url(quote($path + "." + $extmod)) format(quote($format)), comma);
}
@font-face {
font-family: quote($name);
font-weight: $weight;
font-style: $style;
// font-display: block;
src: $src;
}
}
