Functions

func EmbedDeclaration

func EmbedDeclaration(fsys fs.FS, decl *css.Declaration) error

func EmbedFont

func EmbedFont(fsys fs.FS, decl *css.Declaration) error

EmbedFont parses a @font-face src and embeds the woff font variant, preserving links to the other variants. It will always make the woff embed the first item in the list of fonts so that browsers that pick the first match will use that one.

func ParseFontSrc

func ParseFontSrc(tokens []Token) (map[string]string, error)

ParseFontSrc takes a list of Token tokens and parses them into a map indexed by the font format.

func ParseWriteSheet

func ParseWriteSheet(fsys fs.FS, f string, o io.Writer) error

func StringRule

func StringRule(fsys fs.FS, out io.Writer, rule *css.Rule) error
