UPDATE:
I've received feedback from the community that Tailwind can be filtered into a version containing only used classes. Maybe it's not that bad, but I can't see how it would work for me as adds unnecessary steps to my workflow. "Keep it simple" is my philosophy.

In the ever-evolving landscape of web development, developers are constantly on the lookout for tools and frameworks that promise to make their lives easier and their websites more efficient. One such tool that has gained significant popularity in recent years is Tailwind CSS. Tailwind is praised for its utility-first approach and the ability to rapidly build custom designs without leaving your HTML. However, as with many hyped-up tools, there are often hidden drawbacks that are not immediately apparent. In this post, we’ll explore one of the major downsides of using Tailwind CSS—its sheer size and the unnecessary bloat it introduces.
Recently, I created a simple website using Tailwind to investigate just how big the Tailwind CSS files are and how many lines of code they contain. To my astonishment, the current version of Tailwind CSS downloaded amounted to 154KB. This may not sound overly alarming at first glance, especially in the age of high-speed internet. However, a deeper dive using Chrome’s coverage console revealed a staggering reality: the CSS file contained about 175000 lines of code or 3MB of uncompressed CSS.
Yes, you read that correctly— 175000 lines of CSS code in a single file. This is by far the largest CSS file I have ever encountered. Such a massive file introduces significant bloat and can severely impact the performance of your website.
The primary issue with such a large CSS file is the unnecessary bloat it creates. Bloat refers to the inclusion of redundant or unnecessary code that does not contribute to the functionality of the website. In the case of Tailwind, the utility-first approach means that the CSS file includes styles for every possible utility class, regardless of whether they are used in your project or not. This results in an enormous CSS file that needs to be downloaded every time a user visits your website.
Every time a user loads a webpage, their browser has to parse and render the CSS file. With a file as large as Tailwind's, this process consumes significantly more computing power and resources. This can lead to slower load times, especially on devices with limited processing capabilities, such as mobile phones or older computers. In a world where users expect websites to load almost instantaneously, even a slight delay can result in a poor user experience and potential loss of visitors.
Website speed is a crucial factor in user retention and search engine rankings. A slow-loading website can frustrate users and lead to higher bounce rates. Additionally, search engines like Google consider page speed as a ranking factor. Therefore, using a CSS framework that introduces unnecessary bloat can directly impact your website’s SEO performance and overall user satisfaction.
While it's true that there is a possibility of filtering Tailwind's original CSS to remove unused styles, Tailwind itself doesn't offer an official tool for this purpose. Instead, developers have to rely on third-party tools like PurgeCSS to achieve this. However, using these third-party tools can be a clumsy and often cumbersome process. They require additional configuration and maintenance, which can introduce complexity and potential points of failure into your build process. Moreover, these tools might not always be perfectly accurate, sometimes removing necessary styles or leaving behind unused ones. This adds an extra layer of troubleshooting and can detract from the time-saving benefits that Tailwind initially promises. Thus, while filtering is a potential workaround, it is not a perfect solution and highlights another drawback of adopting Tailwind CSS without careful consideration.
When I viewed websites built with Tailwind, they all seemed to be using much less CSS code, yet were still very bloated. It appears there are tools for JavaScript frameworks that can filter Tailwind, but it's not clear how WordPress developers can access these tools or how easy they are to use. This lack of clarity and straightforward integration for WordPress users further complicates the adoption of Tailwind CSS in traditional CMS environments. The additional steps and potential for errors can be discouraging, especially for developers seeking a streamlined workflow.
The allure of new and shiny libraries promoted by YouTube influencers and other online sources can be tempting. However, as developers, it is our responsibility to thoroughly test and evaluate these tools before integrating them into our projects. While Tailwind CSS offers some benefits, it’s essential to weigh these against the potential drawbacks.
Before adopting any new library or framework, take the time to conduct a thorough analysis. Test the impact on your website’s performance, check for unnecessary bloat, and consider the long-term implications. Sometimes, the initial convenience offered by a tool can lead to significant challenges down the line.
In conclusion, while Tailwind CSS might seem like an appealing option for rapid development, its substantial size and the unnecessary bloat it introduces make it a questionable choice for performance-conscious developers. To speed up your WordPress or any other web project, always test new tools and libraries rigorously. The best choice is often not the one that is most hyped, but the one that aligns best with your performance goals and project requirements.
Stay informed, test diligently, and make choices that ensure your websites are fast, efficient, and user-friendly. Happy developing!
