Juice is a JavaScript library and CLI that inlines CSS stylesheets into HTML by converting CSS rules into style attributes. It is primarily used to prepare HTML emails and embedded HTML for environments that don't support style tags.

Use cases

• inline css into html email templates
• prepare html emails for email clients that strip style tags
• embed html snippets in third-party websites with inline styles
• convert stylesheet rules to style attributes programmatically
• flatten css nesting before inlining
• inline remote stylesheets and image data uris into html

When to choose

• you send html email and need maximum client compatibility
• you need to embed styled html where style tags are unsupported
• you want a mature node.js library with a cli and browser build

When to avoid

• you only need general css processing or minification without inlining
• your target environment fully supports style tags and external stylesheets
• you need a non-javascript runtime
