Using “CSS Variables” Instead of “Custom Properties”

Many web developers often wonder whether it’s correct to refer to CSS custom properties as “CSS Variables.” While both terms are widely recognized, “CSS Variables” has become increasingly accepted, especially in modern discussions, tutorials, and codebases.

The official terminology for this feature is “CSS Custom Properties for Cascading Variables.” The relevant URL slug is “css-variables.” These are variables that are part of CSS and are referred to as “cascading” because their values can be overridden based on specificity, inheritance, or media queries. This means they are dynamic and responsive, changing according to conditions like viewport size or container context.

CSS Variables can be animated, manipulated, and typed explicitly with the @property rule, giving developers greater control. Unlike traditional CSS properties, CSS Variables enable more flexible and maintainable styling, especially in complex projects.

While some may prefer the term “custom properties,” calling them “CSS Variables” has gained popularity and is considered acceptable by many in the web development community. Both terms are accurate, but “CSS Variables” emphasizes their variable-like behavior within CSS, aligning with how programming languages handle variables.

In summary, it’s perfectly fine—and increasingly common—to refer to CSS custom properties as “CSS Variables.” Using this terminology can make discussions clearer and more straightforward, especially when addressing a broader audience or modern CSS features.
