2. Minify CSS/JavaScript in WordPress Using SiteGround

Using SiteGround as your WordPress hosting provider, you can minify CSS files using SiteGround Optimizer.

To minify CSS files in WordPress using SiteGround, follow these steps:

  • Install and flare the SiteGround Optimizer plugin on your WordPress point. After installing it, go to Settings > SG Optimizer > General Settings section and tick on the ‘Enable Minify’ option under the ‘Advanced Configuration’ sub-section. This allows you to use other features of this plugin for better results on your site (e.g., compression).
  • Now go ahead and click on any page from your site where you want all CSS/JS files compressed – this includes admin pages, which are highly optimized by default when accessed through browser tabs (as opposed to being served directly). When viewing this page through the browser tab, click on the SG Optimizer menu in your WordPress admin sidebar – this will take us directly into the SG Optimizer settings section, where we need to scroll down until we reach the ‘Other optimizations’ subsection, where there is a toggle button called ‘Minify JavaScript Files & CSS Style Sheets’ – switches this one ON!
  • That’s all! You can now empty cache by visiting Tools > Clear Cache feature or just by visiting WordPress dashboard -> Performance -> Clear Cache option from left sidebar menu bar then visit any page from your site again – voila!

3. Minify CSS/JavaScript using Autoptimize

Next, you need to install and activate the Autoptimize plugin. You must visit the Settings» Autoptimize runner to configure the plugin settings upon activation.

First, you must check the option ‘Optimize JavaScript Code’ under JavaScript Options. Then scroll down and check the box next to the ‘Optimize CSS code’ option. Don’t fail to click on the Save Changes button to store your settings.

Finally, you can click on the Empty Cache button at any time for your minified files to get loaded into the WordPress site’s cache directory automatically after each time they are generated by javascript/ CSS compression tools (like YUI Compressor).

Conclusion

All 3 of these plugins are excellent for minifying CSS and JavaScript in WordPress. They’re simple and easy to use, which is the most important aspect of optimizing your site’s performance. In the end, you should choose whichever you think works best with your workflow, but there’s no denying that they will all help make your site faster.
