Frequently Asked Questions

Is makeCSS really free?

Yes — every tool on makeCSS.com is 100 % free. There are no hidden paywalls, no account required, and no feature limits. All generators, the code editor, and PRO mode are available to everyone.

Do I need to create an account or sign up?

No. makeCSS works entirely in your browser with zero signup. Your work is saved in your browser's local storage so you can pick up where you left off.

What CSS generators are available?

We currently offer 15 tools: Content Box, Box Shadow, Border, Border Radius, Gradient, Text Shadow, Glassmorphism, CSS Grid, Flexbox, Layout Planner Studio, Table, CSS Minifier & Beautifier, a full HTML/CSS/JS Code Editor with PRO mode, a Code Validator, and a Redirect Generator.

What is PRO mode in the Code Editor?

PRO mode opens a full-screen editing environment with 4 simultaneous, resizable panels (HTML, CSS, JS, Live Preview). You can drag-and-drop to reorder panels, use device preview (mobile & tablet mockups), and access Full Code view with auto-split — all for free.

Can I use the generated CSS in commercial projects?

Absolutely. All CSS, HTML, and JavaScript output created with makeCSS tools is yours to use however you like — personal projects, client work, commercial products, open-source — no attribution required.

Does makeCSS work on mobile devices?

The generators and homepage are fully responsive. The code editor is optimised for desktop and tablet screens due to the multi-panel layout, but basic editing works on mobile too.

How do I copy the generated code?

Every generator and the code editor include a one-click copy button. Just click “Copy” next to the code output, and it's on your clipboard — ready to paste into your project.

What are presets?

Presets are professionally designed starting points. Each generator ships with curated presets (200+ across all tools) so you can start from a polished design and tweak to fit your needs instead of building from scratch.
