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 juice library.
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.
