What is Minify and When Do You Need it?
Minify is a term which is used to describe a method that makes your website file size smaller. It completes this task by removing lines, white spaces and unnecessary characters from the source code.
Usually, it is suggested to use only for files which are sent to user’s browsers. It includes JavaScript, CSS and HTML files. In addition, you can also minify PHP files too. PHP is a server side programming language and if you minify it, it will not improve the load speed for your users.
The main advantage of minifying files is to improve the performance and speed of WordPress.
Compact files load faster and improve the speed of your site.
Some experts are of the view that the performance improvement is very small for most websites.
The minification process only decreases few kilobytes (kb) of data on WordPress websites. You can also reduce the pageload time by optimizing images for web..
Here is an example of normal CSS code:
body {
margin:20px;
padding:20px;
color:#333333;
background:#f7f7f7;
}
h1 {
font-size:32px;
color#222222;
margin-bottom:10px;
}
After minifying the code it will look like this:
body{margin:20px;padding:20px;color:#333;background:#f7f7f7}h1{font-size:32px;margin-bottom:10px}
