Question

css

What is the difference between the two web designs:

• Responsive
  
• Adaptive
  

(there are few texts on the Internet on this topic, but the definitions are rather vague)

Answer 1

Responsive (fluid, responsive) design uses %, vh/vw and similar "rubber" values ​​that change depending on the screen size, as well as media queries. The responsive version uses the same HTML template and the mobile user downloads the same content as the desktop version in its entirety. Responsive design has in advance several versions of the site for different sizes (320px, 760px, 1024px, etc.), which do not load extra elements as responsive if they are not on the page.
