Why Use a CSS Formatter to Beautify Your CSS?

Using a CSS formatter to beautify your code means converting minified or messy CSS into clean, readable code. Here’s why it matters:

• Saves time: Automating formatting frees you from tedious manual cleanup and helps focus on writing new features.
• Looks professional: Pretty CSS shows attention to detail and coding discipline, which is important when delivering projects to clients or working in professional environments.

If you’re serious about CSS development, a CSS beautifier is a must-have in your toolkit.
