Media queries are a way to apply different styles to a web page based on the characteristics of the device or browser being used to view the page. They are typically used to create responsive designs that can adjust to different screen sizes and orientations.
To use media queries, you first define a set of styles that should be applied to a page under certain conditions. For example, you might define a set of styles that should be applied when the screen width is less than 600 pixels.
Here's an example of a media query that would apply styles to a page when the screen width is less than 600 pixels:
```
@media (max-width: 600px) {
/* Styles to apply when screen width is less than 600 pixels */
}
```
You can also chain multiple conditions together using the `and` keyword. Here's an example of a media query that would apply styles to a page when the screen width is between 600 and 900 pixels:
```
@media (min-width: 600px) and (max-width: 900px) {
/* Styles to apply when screen width is between 600 and 900 pixels */
}
```
Media queries can be used to adjust a wide range of styles, including font sizes, margins and padding, positioning, and more. They are an essential tool for creating responsive designs that look great on any device.
