Optimize JavaScript and CSS

Reducing the size of CSS and JavaScript files that slow down page loading can improve your overall Core Web Vital score and user interaction.

Delay loading of JavaScript files
While the browser loads the JavaScript files, users cannot interact with the web page. This is why you may sometimes see the term "render-blocking JavaScript." Deferring your JavaScripts means that the browser will only process and load the JS files after parsing the HTML document.

In other words, your website will render much faster because there will be nothing to block the process.

Minify CSS and JS files
To make it easier to read, developers often leave rcs data cambodia spaces or comments in CSS and JS files. However, not all of these characters in the code are essential for the browser.

Minification optimizes your code by removing all unnecessary characters, which helps improve rendering time and speed up websites.

Remove large page elements and tedious tasks
Reducing time-consuming and labor-intensive tasks helps prevent delays in responding to user interactions. A time-consuming task is any piece of JavaScript code that takes more than 50 milliseconds to execute. Large page elements such as videos or background images can slow down code execution and impact INP.
