Introduction to CSS Compressor
Compressor in CSS is used to removes the unnecessary characters in the CSS source code to reduce the file size and make files to load faster than as before compressing. When a user requests any web page then instead of sending the actual CSS full version file, if we sent a compressed version file then it results in faster response time and lower bandwidth cost. Therefore it improved the browser website speed and accessibility, so it helps the search engine ranks moving up. The unnecessary characters mean white spaces, line breaks, block delimiters, comments etc. So minified CSS file will remove all these characters in the source code. The compressed CSS file has an extension with “fileName.min.css”.
Advantage: Improves website speed and accessibility.

How does Compressor work in CSS?
It works for removing white spaces, line breaks, block delimiters, comments, etc. to reduce the size of the application file.
Syntax:
div
{
//CSS styles
}
img
{
//CSS Styles
}
After compressing the code then Syntax:
div{//CSS styles}img{//CSS Styles}
Explanation: As you can see in the above after compressing the code all empty spaces and blank space are removed.
Examples to Implement CSS Compressor
Examples with Code: All the below examples I have used https://csscompressor.com/ online compiler.
1. Border Styles and Text color
Code:
.img1 {
left: 0px;
top: 0px;
position: relative;
z-index: -11;
}
h1
{
color:blue;
text-align: left;
}
.p1
{
border: dashed 3px pink;
font-size: 27px;
color:brown;
}
.img2 {
left: 0px;
top: 0px;
position: absolute;
z-index: -12;
}
h2
{
color:blue;
text-align: right;
}
.p2
{
border: solid 2px orange;
font-size: 25px;
color:green;
}
Output:
