Frequently Asked Questions
Basics
What is Tailwind CSS?
Tailwind CSS is a utility-first CSS framework that provides low-level utility classes to build custom designs directly in your HTML. Instead of writing custom CSS, you compose styles using pre-built classes like flex, text-center, bg-blue-500, and p-4.
How do I use this converter?
- Paste your CSS code into the left input panel.
- Click "Convert to Tailwind" to transform CSS to Tailwind utility classes.
- Review the generated classes in the right output panel.
- Copy the result to use in your HTML class attributes.
How accurate is the conversion?
The converter handles most common CSS properties including layout (flex, grid), spacing (margin, padding), typography (font-size, font-weight), colors, borders, and effects. Exact pixel values are mapped to the closest Tailwind spacing/scale values. Complex or custom values may need manual adjustment.
Usage Tips
Does it support all Tailwind classes?
The converter supports the most commonly used Tailwind utility classes. For advanced or custom Tailwind configurations, some generated classes may need manual refinement. Use the result as a starting point and adjust based on your Tailwind config.
Can I convert multiple CSS rules at once?
Yes. Paste any CSS snippet with multiple rules and selectors. Each selector is processed individually, and the output groups classes by selector. This helps you see which Tailwind classes apply to each HTML element.
How are colors converted?
Colors are matched to the closest Tailwind color palette values. For example, #3B82F6 maps to blue-500, #1a1a1a maps to gray-900, and white/black map directly to white/black. Named CSS colors are also supported.
