Overview

Represents the @font-face directive.

Multiple @font-face rules can be used to construct font families with a variety of faces. Each @font-face rule specifies a value for every font descriptor, either implicitly or explicitly. Those not given explicit values in the rule take the initial value listed with each descriptor in the w3.org specification.

If multiple declarations of @font-face rules, that share the same ‘font-family` and `src` values are present, the last declaration overrides the other.

‘Font-family` property is saved downcased, since the user agents, when matching font-family names, do it in a case-insensitive manner.

Instance Method Details

#==(other) ⇒ Object

Checks, whether two @font-face declarations are equal.

No need to check, whether both font-faces have the same keys, since they are also initialized with the default values.

Parameters:

  • other (FontFace) —

    the @font-face to compare this with.

end

#family ⇒ String?

Returns font-family name, if set.

Returns:

  • (String, nil) —

#valid? ⇒ Boolean

Tells, whether this rule is valid or not.

@font-face rules require a font-family and src descriptor; if either of these are missing, the @font-face rule is invalid and must be ignored entirely.

Returns:

  • (Boolean)
