What is CSS Aggregation and Compression?

CSS aggregation and compression are techniques used to improve the performance of a website by reducing the number of HTTP requests and the size of CSS files. CSS aggregation involves combining multiple CSS files into a single file, which can reduce the number of HTTP requests and improve page load times. CSS compression, on the other hand, involves compressing the CSS code to reduce its size and improve page load times.
