API

getStylesData(html, options, callback)

options.applyStyleTags

Type: Boolean
Default: true

Whether to inline styles in <style></style>.

options.removeStyleTags

Type: Boolean
Default: true

Whether to remove the original <style></style> tags after (possibly) inlining the css from them.

options.preserveMediaQueries

Type: Boolean
Default: false

Preserves all media queries (and contained styles) within <style></style> tags as a refinement when removeStyleTags is true. Other styles are removed.

options.codeBlocks

Type: Object
Default: { EJS: { start: '<%', end: '%>' }, HBS: { start: '{{', end: '}}' } }

An object where each value has a start and end to specify fenced code blocks that should be ignored during parsing. For example, Handlebars (hbs) templates are HBS: {start: '{{', end: '}}'}. Note that codeBlocks is a dictionary which can contain many different code blocks, so don't do codeBlocks: {...} do codeBlocks.myBlock = {...}.

Special markup

data-embed

When a data-embed attribute is present on a <style></style> tag, style-data will not inline the styles and will not remove the <style></style> tags.

This can be used to embed email client support hacks that rely on css selectors into your email templates.

cheerio options

Options to passed to cheerio.
