Media queries are a key feature of CSS that enable developers to create responsive designs by applying different styles based on the characteristics of the user's device. This allows websites to adapt to various screen sizes, resolutions, orientations, and more, providing an optimal viewing experience across all devices. In this article, we will explore the basics of media queries, how they work, and how to use them effectively with detailed examples and explanations.
Basic Syntax of Media Queries
Media queries are written using the @media rule, followed by a media type and one or more expressions that define the conditions under which the styles should be applied. The basic syntax is as follows:
@media media-type (expression) {
/* CSS rules here */
}Common media types include screen (for computer screens), print (for printed documents), and all (for all devices).
Using Media Queries for Responsive Design
Media queries are widely used in responsive design to apply different styles based on the width of the viewport. This ensures that the layout adjusts to different screen sizes, providing an optimal experience for users on various devices.
Example:
/* Default styles for desktop */
.container {
width: 80%;
margin: 0 auto;
}
/* Styles for tablets */
@media only screen and (max-width: 768px) {
.container {
width: 90%;
}
}
/* Styles for smartphones */
@media only screen and (max-width: 480px) {
.container {
width: 100%;
padding: 10px;
}
}Supporting HTML:
<!DOCTYPE html>
<html>
<head>
<link rel="stylesheet" href="styles.css">
</head>
<body>
<div class="container">
<p>This container will adjust its width based on the viewport size.</p>
</div>
</body>
</html>Combining Multiple Media Queries
Media queries can be combined using logical operators like and, or, and not to create more complex conditions. This allows for greater flexibility in applying styles based on multiple criteria.
Example:
/* Styles for devices with a screen width between 600px and 1200px */
@media only screen and (min-width: 600px) and (max-width: 1200px) {
.container {
background-color: #f1c40f;
}
}
/* Styles for high-resolution screens */
@media only screen and (min-resolution: 2dppx) {
.container {
border: 2px solid #e74c3c;
}
}Supporting HTML:
<!DOCTYPE html>
<html>
<head>
<link rel="stylesheet" href="styles.css">
</head>
<body>
<div class="container">
<p>This container will change its background color and border based on the media query conditions.</p>
</div>
</body>
</html>Media Query Ranges
Media query ranges allow you to apply styles based on a range of values, such as screen width or height. This is useful for creating responsive designs that adapt to various device sizes.
Example:
/* Styles for devices with a screen width between 480px and 768px */
@media only screen and (min-width: 480px) and (max-width: 768px) {
.container {
font-size: 18px;
}
}
/* Styles for devices with a screen height of at least 800px */
@media only screen and (min-height: 800px) {
.container {
padding: 20px;
}
}Supporting HTML:
<!DOCTYPE html>
<html>
<head>
<link rel="stylesheet" href="styles.css">
</head>
<body>
<div class="container">
<p>This container will adjust its font size and padding based on the media query ranges.</p>
</div>
</body>
