How Can I Improve Website Performance?

One of the first steps in improving website performance is to identify and eliminate unnecessary requests. Browsers have a limit on how many network requests they can handle in parallel, and too many of them can lead to blocking. You can reduce the number requests to increase the speed of your website by calculating the minimum time it takes to render an object. Eliminate unnecessary plugins. To boost WordPress performance, consider removing any unnecessary plugins or external resources.

Optimizing JavaScript

Optimizing JavaScript’s processing speed is essential for websites that use JavaScript. According to the HTTP archive the majority of webpages contain JavaScript. This accounts for about 15% of the page’s weight. That’s approximately 400KB for desktop users. It will be about 360KB for mobile users. Additionally, the first connection required for a page to load takes around 14 KB. You can optimize performance by using caching, minifying and tree shaking.

You can optimize JavaScript on your website by first identifying where it is being used. PageSpeed Insights can help you identify where JavaScript is used on your site. If you find JavaScript you don’t use, you can remove it from your website. To improve website performance, you can also remove deferred first-party JavaScript. Finally, you can test your code in various browsers and environments to reduce the transmission time.

Although the individual JavaScript optimization tips will only give you a small boost in performance, when combined, they will significantly increase the speed of your website or application. If you don’t have time to implement all the optimization tips, you can optimize JavaScript for website performance according to the number of visitors you expect. It will also be easier to remember the techniques if you have a deadline.

Optimizing CSS

There are several ways to optimize CSS for better website performance. The containment property can address many common performance issues. If the containment property is correctly used, it will allow the browser to optimize the process of specific blocks of DOM contents. Browsers will minimize the number of files required to render your site. The containment property should be used only to address known performance issues and should be limited to a small number of elements.

One of the most common ways to optimize CSS is to write good code. Although this is the best way to optimize CSS, there are many tools and solutions available that will optimize CSS for your needs. These tools are listed below in ascending rank according to their impact on performance. The first tool is styled-components. It was designed to simplify styling React components. But, improper use of this tool could cause site performance problems. Adding stylesheets to a page without optimizing them will slow down the site.

CSS files must be minified to reduce their size. Developers should also be aware of the size of CSS files. Unused CSS can obstruct rendering, interactivity, and the user experience. To make sure that CSS files are smaller, developers should make sure to remove unused CSS, minify CSS files, and prioritize critical CSS. It is also a good idea not to render-critical elements but to use lazy loading. Finally, images and fonts need to be optimized. These tasks can be automated by the developer.
