Less.js interview questions

About Less.js

Less.js is an amazing little tool that extends CSS with the addition of variables, mixins, operations and nested rules. Less.js also extends CSS with dynamic behaviour such as variables, mixins, operations and functions. Less.js (or just less) is a CSS pre-processor that can revolutionize the way you write CSS. In other words, less.js simulates what it would be like if less were supported natively in your browser.
