MOD-CSS v4 arrives renewed and is now fully compatible with React and most modern JavaScript and TypeScript frameworks. This update makes it easier to create fast, modular, and highly customizable interfaces by integrating dynamic styles without adding unnecessary weight to the project.
Quick installation: add MOD-CSS to your project with npm using the following command npm i @dev-geos/mod-css and it will be ready to integrate.
React integration: the integration is straightforward. Create a MOD-CSS instance in the root component and call the init method once so that dynamic styles are automatically applied to all child components. This allows managing reactive styles and variables directly from the markup or from data attributes without complex configurations.
The two key attributes: mod or data-mod and var or data-var. With MOD-CSS you only need two attributes to control most of the styling. mod or data-mod is used to apply predefined styles. var or data-var allows managing and editing selectors and variables. Both forms are interchangeable, so you can use the data dash convention or the short version to write faster.
Descriptive practical examples: example 1 a flexible and responsive grid using mod=row$[100%] and inside columns like mod=col$[80%] || lg? col$[60%] mod=col$[20%] || lg? col$[40%] that allow distributing blocks adaptively. example 2 reactive behavior based on screen width with mod=w[100%] bg[blue] || lg? w[75%] || 2xl? w[50%] bg[pink] to change background and width at different breakpoints. example 3 customize a Button component with mod=bg[lightblue] co[#333] br[9px] && focus*hover: co[blue] br[4px] to adjust color, background, and radii in interactive states.
Why choose MOD-CSS: it is ultra-lightweight and avoids unnecessary overhead, features a minimal syntax to write less and do more, supports more than 200 properties to cover most CSS needs, and offers reactive behavior and built-in variables. Additionally, MOD-CSS is universally compatible with React, Vue, Svelte, Angular, and Vanilla JS, making it easy to adopt across diverse teams and projects.
