@media media_type and (media_feature) {
  /* CSS rules to apply when the media feature conditions are met */
}

• Media features - describe a specific characteristic of the user agent, output device or environment.

1. Adjusting Layout with width Media

One common use of media queries is to adapt the layout based on the screen width. for instance, you might want to switch from a multi column layout on larger screens to a single column layout on smaller screens.

exa.

/* Default styles for all screen sizes */
.container {
  width: 100%;
  max-width: 1200px;
  margin: 0 auto;
}

/* Media query for smaller screens */
@media screen and (max-width: 768px) {
  .container {
    max-width: 100%;
    padding: 10px;
  }
}

1. Modifying Styles with Device Orientation

   Target the device orientation using media queries to deliver a tailored experience. for instance, make adjustments when the user switches between landscape and portrait modes.

    /* Default styles for both orientations */
    .image-container {
      width: 50%;
      float: left;
    }
   
    /* Media query for landscape orientation */
    @media screen and (orientation: landscape) {
      .image-container {
        width: 70%;
      }
    }
