In CSS, media queries allow web designers and developers to apply specific styles to a webpage based on the characteristics of the device or browser that is rendering the webpage. Media queries are used to create responsive web designs that adapt to different screen sizes, resolutions, orientations, and device types.

Media queries consist of a media type and one or more expressions that test the characteristics of the device or browser. Media types include all, screen, print, speech, and others. Expressions can test for a variety of characteristics, such as screen width, device height, device orientation, and more.

Here's an example of how to use a media query to apply different styles based on the screen width:

scssCopy code@media (max-width: 768px) {
  /* Styles for screens with a maximum width of 768 pixels */
}

In this example, the styles within the media query will only be applied to screens with a maximum width of 768 pixels. This is commonly used in responsive web design to adjust the layout and styling of a webpage for smaller screens such as mobile devices.

Media queries can also be nested within each other, allowing for more complex testing and styling based on multiple device characteristics. Media queries can be applied to various CSS properties, such as font size, margins, padding, display, and more.

Overall, media queries are a powerful tool in CSS for creating responsive and adaptive web designs that provide a better user experience across different devices and screen sizes.
