This course dives into Tailwind CSS, a utility-first CSS framework for rapidly building custom user interfaces. It emphasizes how Tailwind CSS differs from traditional CSS frameworks by providing low-level utility classes that can be composed to build any design, directly in the markup. The course covers the core concepts of Tailwind CSS, including its responsive design features, state variants, and how to apply a mobile-first strategy using its utility classes. Participants learn to harness Tailwind’s configuration to extend its functionality, customize its default theme to suit their design needs, and how to work with plugins to add new utilities. The course also explores the process of purging unused styles to optimize the final build size for production. By the end of the course, learners understand how to efficiently craft responsive and maintainable designs with Tailwind CSS, enabling them to rapidly prototype and iterate on their web projects.
