What is Minify CSS and JS? Get to know the benefits for your website

Minify CSS and JS is a technique used to reduce the size of CSS (Cascading Style Sheets) and JS (JavaScript) files on a website. In web development, CSS is used to organize the appearance and layout of pages, while JS is used to provide dynamic interactions and functions on web pages. Even though both have different roles, both can be minified to optimize website performance.

The difference between CSS and JS lies in their function. CSS is used to regulate the appearance and layout of web pages, such as color, text size, and position of elements on the page. Meanwhile, JS is used to provide dynamic interactions and functions on web pages, such as form validation, animation, and dynamic manipulation of page elements.
