Converts a bunch of SVG icons to CSS data URLs with PNG fallbacks. Inspired by grunticon, but simpler and not requiring grunt.
Takes an array of file paths and an options object. Available options are:
defaultWidth: default icon width in pixels, when unspecified by the SVG file. The default is
defaultHeight: default icon height in pixels, when unspecified by the SVG file. The default is
cssPath: path to generated CSS file. The default is
pngDir: path to the directory where PNG files are placed, which will be created if nonexistent. The default is
cssUrlPrefix: path to PNG files used by CSS URLs. By default, the value of pngDir is used.
cssSelector: a function taking an SVG path and a variant (see below) as arguments, and returning the CSS selector for the variant. The default is
base is the basename of the SVG path, converted to lowercase, and with all characters other than letters, digits, hyphen and underscore removed.
selector is variant.selector.
variantsOnly: if true, only build the specified variants (see below). By default, the unmodified icon is also built.
variants: a (possibly empty) array of objects with keys:
Variants allow the creation of alternative versions of the icons by transforming the SVG (e.g., change the color on hover).
