Answer:
d. how its CSS works
Explanation:
A JavaScript utility called PostCSS converts your CSS code into an abstract syntax tree (AST) and then offers an API (application programming interface) for JavaScript plugins to analyze and change it. It offers a wide range of plugins to carry out various tasks, like linting, minifying, inserting vendor prefixes, and many other things.
Postcss-import is one of the most fundamental and crucial plugins to utilize. We can import CSS files into other files using it. Visit src/style.css in the postcss-tutorial repository to see how to utilize this plugin.
