What is CSS?
CSS (Cascading Style Sheets) is a language used to style web pages and user interfaces. It works with HTML to control the layout, colors, fonts, and overall visual presentation of a website or application.
CSS is not limited to web pages-it can also style XML-based documents like SVG and XUL. Combined with HTML and JavaScript, CSS plays a key role in building visually appealing and interactive websites and mobile applications.

What is Minification?
Minification is the process of minimizing code and markup in your web pages and script files. It’s one of the main methods used to reduce load times and bandwidth usage on websites. Minification dramatically improves site speed and accessibility, directly translating into a better user experience. It’s also beneficial to users accessing your website through a limited data plan and who would like to save on their bandwidth usage while surfing the web.
Why minify CSS?
When creating CSS developers tend to use spacing, comments and well-named variables to make code and markup readable for themselves. It also helps others who might later work on the assets. While this is a plus in the development phase, it becomes a negative when it comes to serving your pages. Web servers and browsers can parse file content without comments and well-structured code, both of which create additional network traffic without providing any functional benefit.
To minify CSS files, comments and extra spaces need to be removed, as well as crunch variable names so as to minimize code and reduce file size. The minified file version provides the same functionality while reducing the bandwidth of network requests.
Examples
Before minified
nav ul {
margin: 0;
padding: 0;
list-style: none;
}
nav li {
display: inline-block;
}
nav a {
display: block;
padding: 6px 12px;
text-decoration: none;
}
After minified
nav ul{margin:0;padding:0;list-style:none;}nav li{display:inline-block;}nav a{display:block;padding:6px 12px;text-decoration:none;}
