Media queries in CSS are essential for creating responsive designs, allowing developers to apply different styles depending on the characteristics of the device displaying the content. This includes criteria such as screen size, resolution, orientation, and even the environmental conditions of the device.

The syntax of media queries enables developers to define specific CSS rules that will take effect only when certain conditions are met. For example, a media query can target styles when the viewport width is below a specific pixel value, which is critical for ensuring that designs adapt seamlessly across a plethora of devices, from desktops to tablets and smartphones.

By using media queries, developers can ensure that their web applications offer an optimized user experience tailored for various device specifications, ultimately leading to better usability and accessibility for users.
