    Ruby

    Ruby programming language

    A dynamic, open source programming language with a focus on simplicity and productivity. It has an elegant syntax that is natural to read and easy to write. Ruby is a language of careful balance. Its creator, Yukihiro “Matz” Matsumoto, blended parts of his favorite languages (Perl, Smalltalk, Eiffel, Ada, and Lisp) to form a new language that balanced functional programming with imperative programming. He has often said that he is “trying to make Ruby natural, not simple,” in a way that...

    UIkit

    UIkit

    Lightweight modular front-end framework for developing web interfaces

    ...To be even more efficient, we recommend that you install one of the autocomplete plugins for your favorite IDE or code editor. This saves a lot of time, as you won't have to look up and type all UIkit classes and markup. To use UIkit's CSS and JavaScript, include the files in your own HTML and then create the markup of any of the components. When you have installed UIkit with Less sources, you can compile it and add your own custom theme. Less is the language that the UIkit styles are written in. This allows you to include customizations in the build process, rather than manually overwriting a lot of CSS rules by hand.

    Free Tailwind CSS v4 components for your next project

    ...The components are responsive by default, using grid and flex patterns that adapt cleanly from mobile to widescreen layouts. Accessibility is treated pragmatically: markup favors proper roles and focus states, and most interactive behaviors can be wired with lightweight libraries or framework code if desired. Because everything is plain markup, adoption is frictionless in any stack (React, Vue, Svelte, Rails, Laravel), and designers can tweak styling without refactoring component logic.

Its structure is intentionally opinionated about where code lives and how templates compose, which makes large customizations predictable and maintainable. ...
