The OxyProps - Modern CSS Framework is not a traditional WordPress theme or plugin itself, but rather a specialized utility class framework designed to be used with specific page builders, most notably Oxygen Builder (hence the name "Oxy") and, increasingly, with Elementor and Bricks Builder.
Its primary goal is to bring the efficiency and structured scaling of modern, utility-first CSS frameworks (like Tailwind CSS) directly into the WordPress visual building environment.
OxyProps provides a massive, pre-configured library of CSS variables (also known as CSS Custom Properties or "CSS Vars") that define every aspect of a website's design system:
It standardizes and defines every design value using semantic names:
Colors: Defines a full color palette (primary, secondary, accent, grayscale) using semantically meaningful names like --color-primary-500.
Spacing: Defines a universal spacing scale (e.g., --space-xs, --space-2xl) used for margins, padding, and gaps.
Typography: Defines font families, weights, and a modular scale for font sizes (e.g., --font-size-h1, --text-lg).
Borders, Shadows, Z-Index: Standardized values for effects and layering.
The framework also generates a large number of utility CSS classes based on these variables. Instead of writing custom CSS, you apply pre-built classes:
Instead of writing padding-top: 2rem;, you just apply the class .pt-lg.
Instead of writing color: #3b82f6;, you apply the class .text-primary-600.
Consistency & Speed: It eliminates guesswork. By using semantic variables, every element across the site uses the same, predefined set of values, ensuring global consistency instantly.
Scalability: When you need to change your brand color, you only change the value of the primary color variable (--color-primary-500) in one place. This change instantly propagates across every element on the entire site using that variable.
Modern Workflow: It moves site building closer to modern front-end development practices, allowing developers and designers to work faster and maintain large projects more easily than traditional custom CSS or theme-specific options.
No Vendor Lock-in (CSS Vars): Since the foundation is standard CSS Custom Properties, the core design system is future-proof and readable by any modern browser and developer, regardless of which builder you used.
In short, OxyProps is a powerful foundation that sits beneath your visual builder, providing a highly organized, fast, and scalable design system based on modern CSS variables and utility classes.
