What is minification and when is it required?
The term’minify’ refers to a technique for reducing the amount of your website’s files. It does this by deleting extraneous characters, lines, and white spaces from the original code.
Here’s an example of standard CSS:
The code will look like this once it has been minified:
You may also minify PHP scripts, however, this will have no effect on page load speed for your visitors. PHP is a server-side programming language, which means it operates on servers before anything is transmitted to the visitor’s web browser.
The benefit of minifying files is that they load quicker, which improves WordPress speed and performance.
However, other experts argue that the performance gain for most websites is insignificant and not worth the effort. On most WordPress sites, minification merely reduces a few kilobytes of material. By optimizing pictures for the web, you may minimize the time it takes for a website to load.
This technique is simpler and should be used by all users. It works no matter which WordPress hosting service you choose.
WP Rocket is the most effective WordPress caching plugin available. It makes it simple to add caching to WordPress and boost website performance and page load times dramatically.
See our article on how to install and configure WP Rocket in WordPress for more information.
After activating WP Rocket, go to Settings » WP Rocket and choose the ‘File Optimization’ option.
You must tick the Minify CSS files option from here.
WP Rocket will then display a warning that this may cause issues with your site. Click the ‘Activate Minify CSS’ button to get started. If this feature creates any trouble with your website, you can easily disable it.
After that, don’t forget to save your changes by clicking the Save changes option.
If you use SiteGround as your WordPress hosting provider, you may use SiteGround Optimizer to minify CSS files.
The SiteGround Optimizer plugin is a performance optimization tool that runs on their own platform. It works great with their Ultrafast PHP to speed up the loading of your site.
After that, go to your WordPress admin sidebar and click on the SG Optimizer menu.
This will lead you to the options for SG Optimizer.
From here, go to ‘Other Optimizations’ and click the ‘Go To Frontend’ button.
On the next page, enable the toggle next to the ‘Minify CSS files’ option.
That concludes our discussion. You may now browse your website and load minified versions of CSS and JS files by clearing your WordPress cache.
This option is advised for those who are not using WP Rocket and are not on SiteGround.
To adjust the plugin settings, go to Settings » Autoptimize once it’s been activated.
Then, scroll down to the CSS Options section and tick the box next to the ‘Optimize CSS code’ option.
Remember to click the Save Changes button to save your changes.
