Custom CSS Properties
What are CSS Preprocessors?
CSS Preprocessors are the key ingredients and must have tools for CSS development. Pre-processors extend CSS with variables, operators, interpolations, functions, mixins and many more other usable assets. These SASS, LESS and Stylus are the well known.
Why Pre-Processing CSS?
CSS preprocessors are a standard for web development. One of the main advantages of preprocessors is that they enable you to use variables. This helps you to avoid copying and pasting code, and it simplifies development and refactoring.
We use preprocessors to store colors, font preferences, layout details — mostly everything we use in CSS.
But preprocessor variables have some limitations:
- You can’t change them dynamically.
- They aren’t aware of the DOM’s structure.
