How do you work with responsive design? What approaches do you use?

For responsive layout, I usually use a combination of the following approaches:

• Media Queries (CSS Media Queries): allow changing styles depending on screen width, device orientation, and other characteristics.
• Flexible units of measurement: such as %, vw, vh, rem, which allow elements to adapt to the screen size.
• Flexbox and CSS Grid: for building flexible and responsive layouts.
• Mobile-first approach: I first write styles for mobile devices, then expand for larger screens.
• Using ready-made CSS frameworks: such as Bootstrap or Tailwind, which have built-in support for responsiveness.

Example of a media query:

.container {
  width: 100%;
}

@media (min-width: 768px) {
  .container {
    width: 750px;
  }
}

@media (min-width: 1200px) {
  .container {
    width: 1170px;
  }
}

This approach allows adjusting the container width for different screen sizes.
