[Sass]: Font mixin

Hi. Today I will show you my Sass mixin to generate a font and how to add it from the local assets folder.

[1]. For generate:

$ffBack: -apple-system, BlinkMacSystemFont, "Segoe UI", Roboto, "Helvetica Neue", Arial, sans-serif, "Apple Color Emoji", "Segoe UI Emoji","Segoe UI Symbol", "Noto Color Emoji"

=ft($fz, $lh: 16, $fw: inherit, $ff: null) 
  $lh: $lh/$fz
  $fz: $fz/16 + rem

  @if($ff) 
    $family: $ff, $ffBack
    font: $fw $fz/$lh $family

  @else 
    font-weight: $fw
    font-size: $fz
    line-height: $lh

And for usage, we just call it a mixin:

h1
  +ft(32, 38, 700)

h2
  +ft(28, 32, 700, "Inter")  

Looks like this CSS.

[2]. Add font from local assets folder (compiled styles and font folders inside assets) [code]:

$fontSrc: '../fonts'

$fntName: (Montserrat-Black, 900), (Montserrat-Bold, 700), (Montserrat-SemiBold, 600), (Montserrat-Medium, 500), (Montserrat-Regular, 400), (Montserrat-Light, 300)

=font($fntName, $fntSrc)    
    @each $fnt, $fntw in $fntName
        @font-face 
            $fntFldr: 'Montserrat'
            font-family: '' + $fnt + ''
            font-style: normal
            font-weight: #{$fntw}
            font-display: swap
            src: local('' + $fnt + ''), local('' + $fnt + ''), url($fontSrc + '/' + $fntFldr + '/' +'#{$fnt}.woff') format('woff'), url($fontSrc + '/' + $fntFldr + '/' +'#{$fnt}.woff2') format('woff2'), url($fontSrc + '/' + $fntFldr + '/' +'#{$fnt}.ttf') format('ttf')

+font($fntName, $fontSrc)

It looks like this:
