How Less Code Formatter Works

Format your Less code in three simple steps

Paste Your Code

Copy your unformatted or messy Less code and paste it into the input editor. The formatter supports standard Less syntax and common formatting patterns.

Hit the "Format Code" button and watch as our intelligent formatter instantly restructures your code with proper indentation, spacing, and Less best practices.

Copy or Download

Your beautifully formatted code appears in the output panel. Copy it to your clipboard with one click or download it as a .less file for immediate use in your projects.

Less CSS Formatting Best Practices

Writing clean and well-structured Less code improves stylesheet readability, maintainability, and scalability in modern web projects.

1. Consistent Indentation

Maintain a uniform indentation style across all Less files:

Use 2 spaces per indentation level.
Indent nested rules and mixins clearly.
Avoid mixing tabs and spaces.

2. Clean Nesting Structure

Keep nested selectors readable and manageable:

Avoid deep nesting that increases selector complexity.
Limit nesting levels for better maintainability.
Use nesting only when it improves clarity.

3. Logical Spacing

Use spacing to separate logical blocks:

Add blank lines between selector groups.
Separate variables, mixins, and rules clearly.
Improves readability in large Less files.

4. Meaningful Variable Names

Choose descriptive names for Less variables:

Use clear names like @primary-color.
Avoid vague names like @c1.
Follow consistent naming conventions.

5. Organize Mixins

Structure reusable mixins for clarity:

Group related mixins together.
Keep mixins concise and readable.
Document complex mixins when necessary.

6. Use Automated Formatters

Automate Less formatting for consistency:

Use Prettier or stylelint.
Ensure consistent formatting across teams.
Reduce manual formatting errors.

Before Formatting

@primary:#4caf50;

.card{border:1px solid #ccc;padding:15px;
h2{margin:0;color:@primary;}
p{font-size:14px;color:#666;}
button{background:@primary;color:#fff;border:none;padding:8px 16px;cursor:pointer;}
}

After Formatting

@primary: #4caf50;

.card {
  border: 1px solid #ccc;
  padding: 15px;
  h2 {
    margin: 0;
    color: @primary;
  }
  p {
    font-size: 14px;
    color: #666;
  }
  button {
    background: @primary;
    color: #fff;
    border: none;
    padding: 8px 16px;
    cursor: pointer;
  }
}

Before Formatting

.btn{padding:10px;background:@btn-bg;color:#fff;}

After Formatting

.btn {
  padding: 10px;
  background: @btn-bg;
  color: #fff;
}
