Package Exports
- extract-css
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (extract-css) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

extractCss(html, options, callback)
options.applyStyleTags
Type: Boolean
Whether to inline styles in <style></style>.
options.applyLinkTags
Type: Boolean
Whether to resolve <link rel="stylesheet"> tags and inline the resulting styles.
options.removeStyleTags
Type: Boolean
Whether to remove the original <style></style> tags after (possibly) inlining the css from them.
options.removeLinkTags
Type: Boolean
Whether to remove the original <link rel="stylesheet"> tags after (possibly) inlining the css from them.
options.url
Type: String
How to resolve hrefs. Required.
options.preserveMediaQueries
Type: Boolean
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 tag, extract-css will not inline the styles and will not remove the tags.
This can be used to embed email client support hacks that rely on css selectors into your email templates.
