Top utility-first CSS frameworks

CSS, while straightforward for small projects, becomes challenging in larger ones due to naming inconsistencies and code repetition, prompting developers to create methodologies like BEM and SMACSS, as well as utility-first frameworks like Tailwind CSS and Tachyons. These frameworks aim to simplify CSS by offering utility classes that allow developers to build custom designs directly within HTML files, though they don't fully address CSS's inherent complexity. Tailwind CSS provides a comprehensive library of utility classes for customization without leaving the HTML file, enhancing speed and efficiency, while Tachyons offers a lightweight, mobile-first approach compatible with various front-end frameworks. Shed.css and Basscss also offer solutions through single-purpose classes and human-readable class names, respectively, emphasizing ease of use and responsiveness. Expressive CSS, meanwhile, focuses on providing understandable classes for visual design. Despite utility-first frameworks not solving all CSS issues, they have gained popularity for reducing development headaches and improving workflow efficiency.
