CSS Inliner - Convert Style Tags to Inline CSS

What is CSS Inlining?

CSS inlining is the process of converting external or internal CSS styles into inline styles directly on HTML elements. This is particularly useful for HTML emails, as many email clients don't support external stylesheets or <style> tags.

How to Use the CSS Inliner Tool

Enter your CSS code in the CSS input area
Enter your HTML code in the HTML input area
Click the "Inline CSS" button
The tool will process your code and display the inlined HTML in the result area
You can copy the result to your clipboard or download it as an HTML file

Benefits of CSS Inlining

Email Compatibility: Most email clients require inline CSS for proper rendering
Self-Contained HTML: The HTML file contains all styling information without external dependencies
Improved Loading: No additional HTTP requests for external stylesheets
Consistent Rendering: Ensures styles are applied consistently across different platforms

When to Use CSS Inlining

CSS inlining is most commonly used for:

HTML email templates
Embedded HTML content in third-party platforms
Single-file HTML documents that need to be shared
Web scraping results that need to preserve styling

Limitations

While CSS inlining is useful, it has some limitations:

Increases the size of the HTML document
Makes the HTML harder to read and maintain
Some complex CSS selectors may not be properly inlined
Pseudo-classes and pseudo-elements cannot be inlined
Media queries cannot be inlined

Best Practices

Keep your CSS simple and avoid complex selectors
Use class-based selectors for better inlining results
Test your inlined HTML in different email clients
Maintain a separate non-inlined version for easier maintenance
