gulp-inline-css 
Inline your CSS properties into the
styleattribute in an html file. Useful for emails.
Inspired by the grunt plugin grunt-inline-css. Uses the inline-css module.
- Uses Promises with inline-css version 2.0
This gulp plugin takes an html file and inlines the CSS properties into the style attribute.
/path/to/file.html:
<html>
<head>
<style>
p { color: red; }
</style>
<link rel="stylesheet" href="style.css">
</head>
<body>
<p>Test</p>
</body>
</html>style.css
p {
text-decoration: underline;
}Output:
<html>
<head>
</head>
<body>
<p style="color: red; text-decoration: underline;">Test</p>
</body>
</html>- HTML emails. For a comprehensive list of supported selectors see here
- Embedding HTML in 3rd-party websites.
- Performance. Downloading external stylesheets delays the rendering of the page in the browser. Inlining CSS speeds up this process because the browser doesn't have to wait to download an external stylesheet to start rendering the page.

.pipe(inlineCss({
applyStyleTags: true,

How to resolve hrefs. Must be a string of one character or more. Required.
Relative urls in links will have this value prepended to them. So these links:
<a href="page-relative">Page</a><a href="/root-relative">Root</a><- note leading /
With this option:
inlineCss(html, { url: 'http://example.com/mushroom'})
.then(function(html) { console.log(html); });Will result in
<a href="http://example.com/mushroom/page-relative">Page</a><a href="http://example.com/root-relative">Root</a>
If you don't need this feature, simply set the property to a short string eg {url: ' '} (one space) and everything will work.
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.
