CSS Processors Training

CSS Processors Logo

CSS Processors provides a practical and detailed introduction to the world of CSS processors. A CSS pre-processor is a program that takes the data of one language and converts the data into CSS upon compilation. A CSS post-processor takes existing CSS and refurbishes it to meet the standards of today's browsers. The modern landscape of CSS has been transformed by processors such as LESS, Sass, Stylus, PostCSS and others. The implementation of CSS processors in the workflow boosts efficiency and enforces the DRY (Don't Repeat Yourself) rule. Developers responsible for front-end development and CSS styling are the ideal audience for this course.
