inline-css
Advanced tools
The inline-css npm package is used to convert CSS styles into inline styles within HTML documents. This is particularly useful for email templates where inline styles are often required for proper rendering across different email clients.
Basic Inline CSS Conversion
This feature allows you to convert CSS styles defined in the <style> tag into inline styles within the HTML elements. The example demonstrates converting a simple HTML document with a <style> tag into one with inline styles.
const inlineCss = require('inline-css');
const html = '<html><head><style>h1 { color: red; }</style></head><body><h1>Hello, world!</h1></body></html>';
inlineCss(html, { url: ' ' }).then((result) => {
console.log(result);
});Handling External CSS
This feature allows you to handle external CSS files by specifying the base URL. The example demonstrates converting an HTML document that links to an external CSS file into one with inline styles.
const inlineCss = require('inline-css');
const html = '<html><head><link rel="stylesheet" href="styles.css"></head><body><h1>Hello, world!</h1></body></html>';
inlineCss(html, { url: 'http://example.com/' }).then((result) => {
console.log(result);
});Preserving Media Queries
This feature allows you to preserve media queries in the final HTML output. The example demonstrates converting an HTML document with media queries into one with inline styles while keeping the media queries intact.
const inlineCss = require('inline-css');
const html = '<html><head><style>@media (max-width: 600px) { h1 { color: blue; } }</style></head><body><h1>Hello, world!</h1></body></html>';
inlineCss(html, { url: ' ', preserveMediaQueries: true }).then((result) => {
console.log(result);
});Juice is another popular npm package for inlining CSS into HTML. It offers similar functionality to inline-css, including support for external stylesheets and media queries. Juice is known for its ease of use and comprehensive documentation.
Premailer is a tool that can be used to inline CSS styles in HTML documents. It is available as both a Ruby gem and an npm package. Premailer offers additional features like CSS selector support and HTML minification, making it a versatile choice for email template preparation.
Email-comb is a package designed to clean and inline CSS for email templates. It focuses on removing unused CSS and inlining the necessary styles, ensuring that the final HTML is optimized for email clients. It is a good alternative to inline-css for those looking to optimize their email templates further.
Inline your CSS properties into the
styleattribute in an html file. Useful for emails.
Inspired by the juice library.
This module takes html 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>
Install with npm
npm install --save inline-css
var inlineCss = require('inline-css');
var html = "<style>div{color:red;}</style><div/>";
inlineCss(html, options)
.then(function(html) { console.log(html); });
