CSS to Logical CSS Converter

About CSS2Logical – Created by Ali Nazari

CSS2Logical is an innovative, standalone CSS transformation tool developed and engineered by Ali Nazari. Born out of my own daily web development challenges, this tool allows anyone to instantly convert classic CSS into modern Logical CSS with maximum accuracy and zero hassle. It’s not tied to any specific platform or CMS—just pure, professional-grade code written and optimized by me, Ali Nazari .

Why Logical CSS?

As someone who has worked on multilingual and RTL (Right-to-Left) websites for years, I saw firsthand how Logical CSS is essential for accessibility, easier development, and greater design flexibility. Logical CSS lets you write styles that automatically adapt to LTR and RTL text direction—no more hacks, no more duplicated code, and no more confusion. That’s why I personally set out to make a tool that would finally solve this problem for every developer, everywhere.

How CSS2Logical Works

Simply paste your CSS, SCSS, or SASS into CSS2Logical and hit convert. My custom-built engine detects and transforms all physical-direction properties (like margin-left or padding-right) into their logical equivalents (like margin-inline-start, padding-inline-end, etc.)—with perfect support for nested rules, mixins, variables, comments, shorthands, and even Persian/Arabic numerals. You can also remove comments, minify output, copy results, or download the final logical CSS instantly.

Technical Overview

CSS2Logical, crafted by me (Ali Nazari), leverages powerful regex-based parsing and smart block/line logic to transform all supported properties—even in giant, messy, or complex files. Flags like !important, comments, calc(), and variables are preserved. All processing is server-side for top security and speed—handle even huge stylesheets instantly!

What Sets CSS2Logical Apart?

Most CSS converters only support a few properties or break with advanced SASS/SCSS. My tool is different: I built it for real-world, heavy-duty usage, with features and reliability that other tools simply can’t match. It never drops lines or messes up your code.

Security & Stability

Input is always protected with HoneyPot and CSRF safeguards, and everything is validated and sanitized before conversion. That’s a promise—from me, Ali Nazari, to the global dev community.

Future-Proof & Community-Driven

CSS2Logical is growing fast and open to feedback. Have a suggestion or want a new property supported? Let me know! I, Ali Nazari, am committed to evolving this tool alongside the needs of developers everywhere.

Final Thoughts

I created CSS2Logical to empower developers worldwide—whether you’re working on multilingual sites, refactoring legacy code, or learning CSS best practices. It’s free, robust, and always getting better. Enjoy—and thank you for trusting my work!
