Below is a simple example of CSS minify works.

How do you minimize CSS?

Unminified CSS can be easily minified manually if there are some lines of codes by removing comments, indentation, end semi-colon, and more. Below is a simple example of it.

Consider the CSS in the example below:

/* heading elements */

body {
    color: #33475b

h1 {
    font-size: 2rem;
    font-weight: 700;
    line-height: 2.75rem

h2 {
    font-size: 1.625rem;
    font-weight: 700;
    line-height: 2.25rem

h3 {
    font-size: 1.5rem;
    font-weight: 500;
    line-height: 2.125rem

/* other elements */

p, span {
    font-size: 1rem;
    font-weight: 400;
    line-height: 1.75rem

blockquote {
    font-size: 1.5rem;
    font-weight: 400;
    line-height: 2.375rem

ol, ul {
    list-style: none

table {
    border-collapse: collapse;
    border-spacing: 0

button {
    appearance: none;
    font: inherit;
    margin: 0


As we can see, this code contains line breaks, spaces, indents, and comments to make things more readable and understandable for us. However, the browser doesn’t need any of this information to run the CSS code because while parsing the files, it ignores these extra whitespaces and comments.

Larger files are generally taking more time for processing and ultimately slower website speed.

So after removing all unwanted code from CSS Here’s what the CSS example above looks like after minification:


It may be less readable to us, but to a computer, it looks and works the same.
