Advanced tools
css-inline is a high-performance library for inlining CSS into HTML 'style' attributes.
This library is designed for scenarios such as preparing HTML emails or embedding HTML into third-party web pages.
For instance, the library transforms HTML like this:
<html>
<head>
<style>h1 { color:blue; }</style>
</head>
<body>
<h1>Big Text</h1>
</body>
</html>
into:
<html>
<head></head>
<body>
<h1 style="color:blue;">Big Text</h1>
</body>
</html>
style and link tagsstyle and link tagsInstall with npm:
npm install --save css-inline
import { inline } from "css-inline";
var inlined = inline(
`
<html>
<head>
<style>h1 { color:red }</style>
</head>
<body>
<h1>Test</h1>
</body>
</html>
`,
)
// Do something with the inlined HTML, e.g. send an email
keep_style_tags. Specifies whether to keep "style" tags after inlining. Default: falsekeep_link_tags. Specifies whether to keep "link" tags after inlining. Default: falsebase_url. The base URL used to resolve relative URLs. If you'd like to load stylesheets from your filesystem, use the file:// scheme. Default: nullload_remote_stylesheets. Specifies whether remote stylesheets should be loaded. Default: trueextra_css. Extra CSS to be inlined. Default: nullpreallocate_node_capacity. Advanced. Preallocates capacity for HTML nodes during parsing. This can improve performance when you have an estimate of the number of nodes in your HTML document. Default: 32You can also skip CSS inlining for an HTML tag by adding the data-css-inline="ignore" attribute to it:
<head>
<style>h1 { color:blue; }</style>
</head>
<body>
<!-- The tag below won't receive additional styles -->
<h1 data-css-inline="ignore">Big Text</h1>
</body>
</html>
The data-css-inline="ignore" attribute also allows you to skip link and style tags:
<head>
<!-- Styles below are ignored -->
<style data-css-inline="ignore">h1 { color:blue; }</style>
</head>
<body>
<h1>Big Text</h1>
</body>
