An Incomplete List of CSS Mistakes

Ever wondered what the CSS Working Group would fix if they had a time machine? ?? Today, we’re diving into the design quirks of CSS—the little hiccups and inconsistencies that make you go, “Wait, why is this like that?”

Introduction

CSS is a powerful tool, but it's not without its flaws. Over the years, certain design choices have led to unexpected behaviors, confusing syntax, or just plain weird results. Understanding these mistakes isn't just about pointing fingers—it's about learning from them to write better, more robust CSS.

??Theory: The Pitfalls in CSS Design

Some of these issues stem from the early days of CSS when decisions were made to prioritize backward compatibility or simplicity. However, as the web evolved, these choices sometimes became limitations:

• Inconsistent Naming Conventions: Why doesn’t `z-index` work on all elements, and why is it `-index` anyways? Why we need `interpolate-size` to animate to `auto`?
• Specificity Overload: The cascade is powerful but can lead to unintended consequences when specificity gets out of hand.
• Box Model Confusion: Remember when box-sizing: border-box wasn’t the default? "Yeah, those were dark times."
• Vendor Prefix Chaos: A struggle of adding -webkit-, -moz-, -ms-, and -o- for cross-browser support.
