Exactly, @dimplesaini.230 structure and layout go hand in hand. I’ve learned that if you want to seriously make your website mobile-friendly, switching to relative units like %, em, or rem is a game-changer. It gives your layout breathing room across devices without locking things down. Responsive media is another thing people often miss. Videos embedded with iframes? Wrap them in a responsive container. Want to move faster? Frameworks like Bootstrap or Tailwind CSS offer mobile-first grid systems out of the box. They save time, keep your CSS clean, and make testing across breakpoints a breeze. Why reinvent the wheel when the right tools are already out there?
