What is CSS Minifier and how to use it?

A CSS Minifier is a tool used to remove unnecessary code from CSS source files in order to reduce file size without altering how the CSS file functions in the browser.

It's not a secret that CSS is a handy tool that website owners can use to style pages and content precisely as desired — but too much of it can sometimes mean trouble regarding page load times. If you use large CSS files frequently, it will slow down your site's performance and drive away the visitors. So you need to minimize CSS by removing unnecessary data from the CSS code. The browser can then download and process these files more quickly by using CSS minification, which boosts page performance and enhances the user experience.

In order to compete with the rapidly growing number of impressive technical sites, it helps to strike a balance between engagement and speed. Even though doing that might seem challenging, don't worry; there are plenty of easy ways to improve load times while maintaining your design intent.

What is unnecessary data in a code?

Developers have added formatting, and syntactic best practices to CSS to make the code easier for humans to read. These efficiently increase productivity, aid in debugging and make it simpler to maintain the CSS code. However, they are extra since neither the target platform nor the browser requires them to function.

You might have noticed that most of the CSS code contains line breaks, comments, and indents. Although it simplifies things for us, the browser doesn't need any of this data to execute the CSS code. These extra whitespaces and comments are not taken into account when parsing the files. As a result, the CSS file is bigger than is necessary for it to function properly. This makes website visitors believe that your website or application is slow, which falls short of providing them with the wonderful user experience they expect.

This is why it becomes essential for a person to remove the unnecessary data from CSS and reduce its length.

Why should you use a CSS Compressor?

Increasing your website's speed is the main benefit of using a CSS compressor. Going from a 1-second to a 3-second load time helps to speed things up by 32%. Any small improvement in performance could mean the difference between a visitor choosing to stay or leave. go. Faster pages also improve usability for mobile visitors.

Page speed and loading time also influence its ranking in search engines. A website with high speed is likely to have a higher ranking on social media, and a website with low speed will likely have a lower ranking.

The best part is that you don't need to make any changes to your page's content.

Why should we use CSS Minifier?

The sole purpose of CSS minification is to optimize the CSS code so as to increase the speed of a website. Moreover, CSS minification can make a script up to 20% smaller making the website faster. Some developers will also use it to 'muddle' their code and as a result, it makes the code difficult to read (making it difficult to copy or reverse engineer the code). However, the most common practice for CSS minification is to combine all the CSS files into one single file. The benefit is that it reduces the number of HTTP requests and makes the GZIP compression more powerful.
