What Is a CSS and why do we need CSS files?

As per Wikipedia CSS stands for 'Cascading Style Sheets' and is a stylesheet language used for describing the presentation of a document written in a markup language such as HTML.

CSS is designed to enable the separation of presentation and content, including layout, colors, and fonts. This separation can improve content accessibility, provide more flexibility and control in the specification of presentation characteristics, enable multiple web pages to share formatting by specifying the relevant CSS in a separate .css file which reduces complexity and repetition in the structural content as well as enabling the .css file to be cached to improve the page load speed between the pages that share the file and its formatting.

Minify CSS - What Is a CSS Minifier Tool and Why do we need to Minify CSS?

As we just read above, CSS is a way of giving presentation to the HTML code. Now if you are starting out and creating CSS for a new website, the CSS code and file would be very small, may be in bytes. But as soon as your website grows to a big organizational level website, the CSS code get's huge. The CSS files may be in hundreds of Kilobytes. When a website loads it pulls the css files over the internet.

If the size of the CSS file is small, the loading would not take much time and the website will load quickly, but if the size of the CSS is bigger, the website may be slower to load depending on the spped of the internet of the user.

In order to decrease the size of these CSS files, we follow a process called CSS Minification. Minifying CSS files or code would mean to keep all the code intact, still reducing the size of the files by removing all the white spaces from the CSS code. When we minify css files, we greatly reduce the size of the css file and thereby decreasing the website loading time.

The below image shows you the difference in size between an unminified CSS file and a CSS minified file.
