Returning to the Fundamentals: HTML, CSS, JavaScript, and the Rule of Least Power

Every now and then, I find myself drawn back to web development basics—HTML, CSS, and JavaScript. It’s a lot like the classic hero’s journey: you venture out to explore cutting-edge tools, AI-driven solutions, or other shiny innovations, only to return home and, inevitably, change the color of the “Add to Cart” button to red.

Recently, I stumbled upon a talk by Kilian Valkhof at JSConf Budapest, and it really got me thinking. His insights on simplicity and the Rule of Least Power struck a chord with me, reinforcing the importance of revisiting the basics.

The fundamentals, I’ve come to realize, aren’t static relics of the past. They grow and evolve, albeit at a slower, steadier pace. Recognizing this helps justify the time spent revisiting these familiar tools. For me, it’s not just about practice; it’s about finding fresh perspectives. I’m always on the lookout for elegant, simple solutions that solve problems in ways that are both human-readable and enduring.

Why the Fundamentals Matter

In the ever-changing landscape of frameworks and libraries, it’s easy to feel swept up in the race to adopt the next big thing. But here’s the rub: the more powerful a tool is, the more complexity it brings with it. A shiny new framework may promise speed and efficiency, but it can also introduce challenges—breaking changes, dependency hell, and the constant upkeep required to stay current.

And sometimes, the latest tools simply don’t align with the mission at hand. At the end of the day, web development is about solving problems and getting the job done. Whether you’re using your hands, a hammer, or a laser-guided drone, the goal remains the same.

That’s where the fundamentals shine. HTML, CSS, and JavaScript are the universal languages of the web. They’re resilient, widely understood, and capable of building applications that stand the test of time. Relying on these tools reduces unnecessary dependencies and ensures your work is adaptable across environments.

The Rule of Least Power in Practice

The Rule of Least Power is a principle that emphasizes simplicity and flexibility: use the least powerful tool that can effectively solve the problem. It’s a guiding light for developers seeking solutions that are resilient, maintainable, and accessible.

Benefits of Simplicity

• Resilience: Applications built with simpler technologies are less likely to break in response to browser updates or changing standards.
• Maintainability: Clean, straightforward code is easier for others (and future-you) to understand and build upon.
• Accessibility: Starting with the basics often leads to solutions that work better for a diverse audience, including those using assistive technologies.

For example, take navigation. Could semantic HTML and basic CSS achieve the same result as a JavaScript-heavy solution? In many cases, the answer is yes—and without the added headaches of debugging and dependency management.

Simplicity is Not Limitation

Some might see a preference for the fundamentals as limiting, but I find it freeing. It’s about creating systems that are not only functional but enduring. A dazzling new JavaScript library might deliver impressive features today, but if it’s brittle or overly complex, its brilliance can quickly fade.

In contrast, a well-crafted bit of HTML or CSS can quietly do its job for years without complaint. Simplicity isn’t about avoiding innovation—it’s about making thoughtful, intentional choices that prioritize stability and long-term value.

Final Thoughts

Revisiting the basics isn’t about stepping backward; it’s about recalibrating. For me, returning to HTML, CSS, and JavaScript feels like sharpening a knife before cooking—it ensures I’m making precise, effective cuts instead of hacking away with unnecessary tools.

The Rule of Least Power isn’t just a programming principle; it’s a mindset. It encourages us to ask, “What’s the simplest, most effective way to solve this problem?” Sometimes, the answer will be a new tool or framework. Other times, it’s plain old HTML, CSS, or JavaScript.

And that’s the beauty of it.
