[![NPM](https://nodei.co/npm/style-data.png?downloads=true)](https://nodei.co/npm/style-data/)
> Get the content of style tags.
## Install
Install with [npm](https://npmjs.org/package/style-data)
```
npm install --save style-data
```
## Usage
```js
var getStylesData = require('style-data');
getStylesData(html, options, function (err, results) {
console.log(results.html); // resulting html
console.log(results.css); // array of css rules
});
```
## API
### getStylesData(html, options, callback)
#### options.applyStyleTags
Type: `Boolean`
Default: `true`
Whether to inline styles in ``.
#### options.removeStyleTags
Type: `Boolean`
Default: `true`
Whether to remove the original `` tags after (possibly) inlining the css from them.
#### options.preserveMediaQueries
Type: `Boolean`
Default: `false`
Preserves all media queries (and contained styles) within `` 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, style-data 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.
### cheerio options
Options to passed to [cheerio](https://github.com/cheeriojs/cheerio).
