[![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 `<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](https://github.com/cheeriojs/cheerio).
