What is Critical CSS?
Critical CSS is a part of the CSS code required to render the initial appearance of a website page. In other words, Critical CSS is CSS that is needed to display content that is first visible to the user when the website page is loaded. The difference between regular CSS and Critical CSS lies in the file size and content. Critical CSS only contains CSS code that is relevant to the initial appearance of the page, while regular CSS may contain all the CSS code used on the website.
How Does Critical CSS Work?
Critical CSS works by loading only the CSS code needed to render the initial appearance of the website page. The process of creating and implementing Critical CSS on a website involves analyzing and selecting CSS code that is relevant to the initial appearance of the page. After that, the CSS code can be inserted inline into the HTML or made into a separate file that is loaded asynchronously after the main content of the page has finished loading.
Why is it important to have critical CSS on your website?
Using Critical CSS on your website has many benefits. First, Critical CSS can help increase website loading speed. By only loading the CSS code required for the initial page display, loading times can be accelerated because smaller CSS files can load more quickly. This will provide a better user experience and reduce the bounce rate.
Apart from that, using Critical CSS can also reduce server load. By only loading the CSS code that is relevant to the initial page display, the server does not need to process and send the entire CSS file on each request. This can reduce server resource usage and save hosting costs.
Increase Website Loading Speed with Critical CSS
Critical CSS can help increase website loading speed by loading only the CSS code needed for the initial page display. By reducing the size of the loaded CSS file, loading times can be accelerated. For example, if a website page has 1000 lines of CSS code, but only 100 lines are needed for the initial page display, then using Critical CSS will reduce the size of the loaded CSS file by 90%.
An example of a case of using Critical CSS on a website is when rendering the initial appearance of the home page. On the home page, there are usually elements such as a header, navigation menu, and main content. By using Critical CSS, only the CSS code relevant to those elements is loaded when the home page loads. This will reduce loading times and provide a better user experience.
Reducing Server Load by Using Critical CSS
Using Critical CSS can also help reduce server load. By only loading the CSS code that is relevant to the initial page display, the server does not need to process and send the entire CSS file on each request. This can reduce server resource usage and save hosting costs.
Another positive impact is more efficient use of bandwidth. By reducing the size of the loaded CSS file, bandwidth usage can be reduced. This will reduce hosting costs, especially if your website has many visitors or high traffic.
Improving User Experience with Critical CSS
User experience is an important factor in the success of a website. By using Critical CSS, you can improve the user experience by providing faster loading times and a more responsive initial page appearance. Users will feel satisfied and will not wait too long when the website page loads.
An example of a case of using Critical CSS on a website is when rendering the initial display of a product or article page. On this page, there are usually elements such as the main image, title and short description. By using Critical CSS, only CSS code that is relevant to those elements is loaded when the product page or article is loaded. This will provide an attractive initial appearance and attract users.
Improving SEO by Using Critical CSS
Apart from the benefits for loading speed and user experience, using Critical CSS can also help improve SEO. Search engines like Google pay special attention to website loading speed and user experience. By using Critical CSS, you can increase website loading speed and provide a better user experience, thereby increasing your website ranking in search engines.
Another positive impact is more efficient crawling time by search engines. By reducing the size of the loaded CSS file, crawling time by search engines can be accelerated. This will help search engines to index your website pages more quickly and accurately.
How to Implement Critical CSS on Your Website?
Implementing Critical CSS on your website can be done in a few simple steps. First, analyze and identify the CSS code that is relevant to the initial appearance of the page. Then, the CSS code can be inserted inline into the HTML or made into a separate file that is loaded asynchronously after the main content of the page has finished loading.
Tips and tricks to ensure successful implementation are to carry out regular testing and monitoring. Check that the CSS code loaded is CSS code that is relevant to the initial appearance of the page. If there are changes to the initial appearance of the page, make sure to update the loaded CSS code.
There are several tools and software that can be used to create Critical CSS. Some of them are Critical, Penthouse, and Critical Path CSS Generator. Each tool and software has its own advantages and disadvantages. Before choosing tools or software, make sure to consider your needs and technical capabilities.
Tips for Creating Effective Critical CSS
Creating effective and efficient Critical CSS can be done with a few tips and tricks. First, focus on the CSS code that is relevant to the initial appearance of the page. Avoid entering unnecessary CSS code on the initial page display, because this will reduce the effectiveness of Critical CSS.
In addition, use compression techniques such as minification or merging CSS files to reduce the size of the loaded CSS files. This will help increase website loading speed. Additionally, make sure to update the loaded CSS code if there are any changes to the initial appearance of the page.
