CSS Frameworks
CSS frameworks are pre-prepared libraries of CSS code that provide a foundation for styling web applications, offering reusable components, responsive grid systems, and utility classes to streamline development. They help ensure consistency, improve productivity, and handle cross-browser compatibility issues, allowing developers to build modern, responsive interfaces more efficiently.
Developers should learn CSS frameworks to accelerate front-end development, especially when building responsive websites or web applications that require consistent design systems. They are particularly useful in team environments to maintain code uniformity, and for projects with tight deadlines where rapid prototyping is essential, such as in startups or agency work.
