No one likes slow websites. In fact, many users want to leave the site instead of waiting for the page to load for two seconds or more. Therefore, it is very important for the site to optimize the performance. Fortunately, there are many ways to solve the slow loading time and create the site correctly. Some are related to content, others to the server, and more to the site’s JavaScript and CSS code. Let’s take a look at why website performance optimization is so important. Then it introduces how to optimize JavaScript and CSS on the website. Jump in! The
Just as we have mentioned the important reasons why JavaScript and CSS optimization are important to the success of a website, the performance of a website is closely related to the success of a website. The slower the load time, the worse the user experience (UX) and the higher the utilization. If visitors continue to decrease, the site is certainly difficult to jump. Research shows that improving site performance will increase the conversion rate. This means an increase in sales of e-commerce websites, revenue generating blogs and subscribers to member based websites. In addition, site performance is one of many factors in search engine optimization (SEO). The site loading speed will affect the location on the SERP (search engine results page) and the organic traffic that occurs on the site. The
Since 51% of organic traffic comes from online search, if you miss a high SERP ranking, the site may be seriously delayed. In addition, on average, more than 40% of the revenue comes from natural search, and 91.5% of the searchers reach one of the home page results. That is, improving site performance is critical to attracting visitors. Therefore, optimizing your site’s JavaScript and CSS is a big step in the right direction. Ways to optimize JavaScript and CSS and improve website performance (3 technologies) there are many ways to optimize website speed. Here, we will focus on several ways to optimize site code to speed up loading. The
1. in order to eliminate unnecessary characters, reducing JavaScript and CSS is the process of deleting spaces and other characters that are not necessary for the operation of website code. These elements are usually included in JavaScript, CSS, and HTML files to make them easier to read. However, the computer does not need these additional characters to read the code file. On the contrary, adding content only makes the file larger, so it takes longer to process and load. You can merge JavaScript and CSS files and manually collapse them by removing spaces, comments, and line breaks. However, for large sites with many long files, this is a time-consuming and inefficient process. The
Fortunately, WordPress users have some plug-ins to help them. Fast velocity minify can quickly clean up JavaScript, CSS, and HTML files to improve performance. Male autoptimization is another powerful plug-in for scaling down JavaScript and CSS. You can also handle many other performance related tasks, such as file aggregation and caching, and inserting CSS into page titles. If the male plug-in is used, the shrinking process will be greatly improved after it is removed from the hand. You can view performance differences by quickly removing unnecessary characters from your site code. The
2. use embedded small JavaScript and CSS for code integration JavaScript and CSS \
Pay attention to shortcomings. First, adding too much JavaScript and CSS to an HTML file can cause the size to be too large. If this happens, you may lose all the speed you get because you replace multiple files with a very large file. The
In addition, and more importantly, you cannot cache inline JavaScript and CSS. Caching is another very useful way to improve site performance. The benefits of inline styles and scripts may not outweigh the cost of losing caching. Considering these two factors, carefully consider whether inline JavaScript and \/ or CSS are suitable for the website. You can also use external JavaScript and CSS as an alternative. If you choose to inline JavaScript and \/ or CSS as auto optimization plug-ins, you must manually add JavaScript code to the HTML file. However, CSS can be inlined more quickly through automatic optimization. The
To access the settings that make this possible, you must navigate to Settings > auto optimization, and then click the show advanced settings button. Here you can see two options for adding inline CSS. \
3. in order to load more efficiently, please order styles and scripts, and how the browser loads website information according to the display order of JavaScript and CSS snipt in HTML files. If JavaScript and CSS are in a non optimal position, the loading of the remaining pages may be delayed. In summary, CSS must always be on the androg tag. Instead, JavaScript must be at the bottom of the male tag. This helps the page display faster because the browser cannot display web content unless it first accesses the page’s CSS. The
Instead, JavaScript can continue to load in the background after CSS is loaded. If you move to the bottom, you can load and display all other items in the browser before the JavaScript code is loaded in the background. You can manually order CSS and JavaScript code, or you can let autooptimization handle it. Do I just need to check the optimize JavaScript code? Do you want to optimize CSS code? Box set by the plug-in: in this way, autooptimization will automatically put CSS on the header and push the JavaScript code to the bottom. The plug-in does not need to edit the files on the site manually, because it can prevent errors that may damage the site, so it always has a plus sign. The
Conclusion most web users expect faster loading time. Failure to optimize site speed may have a negative impact on deviation rate, revenue and visibility. Fortunately, there are three ways to optimize JavaScript and CSS to improve site performance. Collapse JavaScript and CSS to remove unnecessary characters. Integrate code using embedded JavaScript and CSS. Order styles and scripts for more efficient loading. Do you have any questions about site performance optimization?
