How To Minify CSS: The Ultimate Guide to Saving Bandwidth and Improving Page Load Times

Optimizing your website for speed is crucial for getting your visitors to stay on your site. The faster the site loads, the more likely they are to stick around. With this in mind, it’s important to minimize the number of requests your page hosts so that the page loads as quickly as possible for our visitors. If you want to know how to minify CSS or HTML or JavaScript, then read on!

What Is Minify CSS?

CSS is a programming language that helps to tell your computer how to display elements on your page. It does this by defining styles and rules and assigning them to HTML tags.

Minifying CSS helps you cut out excess code from the CSS so that it doesn’t take up as much space. This means less data for your visitor to download, which will make the site load faster.

Why Should We Minify CSS?

CSS is the styling language that's used to design the look of your website. It dictates where elements are positioned, how they're styled and more. When you minify CSS, you take out any comments or anything not necessary for the browser to understand what you're trying to do with your CSS.

How to Minify CSS?

Minifying CSS is fairly straightforward. The first step is opening the file in a text editor, like Notepad or TextEdit. Next, find all of the spaces in the document and delete them. This will make the file take up less space on your computer, which will translate to a faster loading time for your visitors.

The next step is to remove all of the comments from the CSS file. Comments are information about what’s happening in that particular section of code, but they aren’t necessary to understand how it works. Removing these parts will help reduce page load time by one second.

Finally, you need to remove any unnecessary code that isn’t impacting your website's loading speed, like hexadecimal color codes or font declarations. Finally, save the changes!

What are the Benefits of Minifying CSS?

Knowing how to minify CSS is crucial for getting your site to load as quickly as possible. When you minify CSS, you are removing unnecessary spaces and comments from the code. This will have a drastic impact on the number of requests your page hosts, which will help your site load faster.

Minifying CSS can also help with your site's loading time if you are using multiple external CSS files. The browser will not have to request each file separately, so it will be one request rather than many. All of these benefits make it clear why knowing how to minify CSS is beneficial!

Yahoo's tool grades your site based on the number of requests it takes for your page to load. It'll grade your site on a scale between 0-100 (with 100 being the best). A grade below 80 means that there are more than two dozen requests on your page and will negatively affect your SEO rankings.
