About CSS to LESS Converter

Our CSS to LESS Converter tool helps you transform standard CSS code into LESS (Leaner Style Sheets) format. LESS extends CSS with dynamic behavior such as variables, mixins, operations, and functions, making your stylesheets more maintainable and easier to work with.

This converter offers two conversion modes:

  • Basic Nesting: Converts your CSS to use LESS's nesting capabilities, which helps organize your code by visually representing the HTML hierarchy in your stylesheets.
  • With Variables: In addition to nesting, this mode identifies repeated values in your CSS (like colors, font sizes, and spacing) and extracts them into LESS variables, making your code more maintainable and consistent.

By converting your CSS to LESS, you can take advantage of features that make your stylesheets more maintainable, reusable, and easier to understand.

LESS Features and Benefits

Variables

@primary-color: #3b82f6;

.button {
  background-color: @primary-color;
  color: white;
}

.link {
  color: @primary-color;
}

Variables allow you to specify a value once and reuse it throughout your stylesheet. If you need to change the value, you only need to update it in one place.

Nesting

.header {
  background-color: #f5f5f5;
  
  h1 {
    color: #333;
    font-size: 24px;
  }
  
  p {
    color: #666;
    font-size: 16px;
  }
}

Nesting allows you to organize your CSS in a way that follows the HTML hierarchy, making it more readable and maintainable.

Mixins

.border-radius(@radius) {
  border-radius: @radius;
  -webkit-border-radius: @radius;
  -moz-border-radius: @radius;
}

.button {
  .border-radius(5px);
}

Mixins allow you to embed all the properties of a class into another class. They can also take parameters, making them powerful for creating reusable style patterns.

Operations

@base-size: 16px;
@large-size: @base-size * 1.5;

.title {
  font-size: @large-size;
  margin-bottom: @base-size + 8px;
}

LESS allows you to perform arithmetic operations on values, making it easier to create consistent sizing and spacing in your designs.
