Fonts with multiples weights

[tutods]

Hi!
I try setting a custom font in my project using this code:

fonts:
    # basically the text
    sans: 'Poppins'
    # use with `font-serif` css class from windicss
    serif: 'Playfair Display'
    # for code blocks, inline code, etc.
    mono: 'Fira Code'
   # provider
    provide: 'google'

But when I set on class font-300, no changes on font-weight.
Can help me?
