Don’t be overwhelmed by the table below; most optimizations can be easily achieved with an optimization plugin. I personally use the free Speed Optimization plugin that comes bundled with SiteGround’s Hosting plan. However, there are several other options, including W3 Total Cache (W3TC), WP Rocket, and FlyingPress.

Implementing this feature can be achieved by using an Optimization Plugin:
Minifying CSS files involves reducing their size by removing comments, unnecessary white spaces, and redundant code. By doing so, the speed at which browsers download and execute these files is optimized. CSS is inherently render-blocking; browsers hold back on displaying content until the CSS files are downloaded, parsed, and applied. For complex page layouts and styles, CSS files might be larger than what’s required for effective page display.
During a webpage’s loading process, browsers need to download, interpret, and execute CSS files, an activity taking place on the main thread. This monopolizes the main thread, temporarily pausing it from other tasks during the initial phase of page load.
The larger the CSS file, the more time it takes to download, translating to a prolonged blocking of the main thread. Performance can be boosted by decreasing the size of these CSS files. Minification achieves this by trimming down the CSS files, omitting parts that don’t influence browser rendering.
How to Minify CSS? It’s a best practice to integrate CSS minification into your development workflow, ensuring your production website is primed for top-tier performance. To implement this, consider one of the following CSS minification methods:
