Less
Less (sometimes written as LESS) is a tool that makes writing website styling code easier and more efficient. Think of it as an advanced way to write CSS, which is the basic code that controls how websites look. Instead of writing repetitive styling code, Less allows developers to use variables, reusable pieces, and simple calculations to create website designs faster and with fewer errors. It's similar to other tools like Sass or Stylus. When developers mention Less in their resumes, they're showing they know how to write modern, maintainable website styling code.
