Frequently Asked Questions
What is responsive web design (RWD)?
Responsive web design is a development approach where websites automatically scale their layouts and elements to display optimally across various user screens and viewport widths (ranging from compact mobile smartphones to wide desktop displays).
Why are CSS media query breakpoints important?
CSS media query breakpoints allow developers to write custom CSS rules that apply only when the user viewport matches specific width criteria (e.g., max-width: 768px for tablet grids), ensuring layout elements shift fluidly to avoid broken columns or overflow clips.
