What is CSS to SCSS Conversion?
SCSS (Sassy CSS) is a CSS preprocessor that extends CSS with powerful features like variables, nesting, mixins, and functions. Converting CSS to SCSS makes stylesheets more maintainable and DRY (Don't Repeat Yourself). This tool automates the conversion by inferring nesting from repeated selectors, converting CSS custom properties (--var) to SCSS variables ($var), and properly nesting pseudo-classes with the & parent selector.
This tool runs entirely in your browser. No data is sent to any server.

Frequently Asked Questions
How does nesting inference work?
The tool analyzes selectors with common prefixes. For example, .nav, .nav-item, and .nav-link are grouped under a parent .nav rule. Common prefixes are detected and nested automatically using the & parent selector.
What happens to CSS custom properties?
CSS custom properties defined with --name inside :root or any rule are converted to SCSS variables ($name). References using var(--name) are also updated to $name.
Are @media queries supported?
Yes. @media queries are preserved and can optionally have their nested rules further optimized with nesting inference. Other at-rules like @keyframes, @font-face, and @supports are also fully supported.
What is the difference between SCSS and Sass?
SCSS uses curly braces and semicolons (like CSS), while Sass uses indentation-based syntax. This tool converts to SCSS, which is the more widely adopted syntax and is fully compatible with CSS.
