Instance Method Details

Public: Generates a Google Webfonts link tag

If you need to specify a font size, use a Hash. Symbols will be titleized, so if the font you’re using uses a specialized case (e.g: “PT Sans”), then you’ll need to use a String.

You can specify subsets by using the :subset option. Note that this must be a Symbol. “Subset” and “subset” would be turned into a font.

options - The font options. This can be a String, Symbol, or Hash, or

a combination of all three.
