CSS Media Queries Explained: A Beginner’s Guide

CSS Media Queries are essential tools for creating responsive websites. They allow your website layout to adapt to different screen sizes and device types, improving user experience. Let’s understand media queries easily.

What are CSS Media Queries?

Media queries are CSS rules that detect characteristics of devices like screen size, resolution, or orientation, letting you apply specific styles for each condition.

Why Use Media Queries?

Responsive Layouts: Makes your website look good on phones, tablets, and desktops.
Better User Experience: Improves readability and navigation on all devices.
SEO Benefits: Google favors responsive, mobile-friendly websites.

Basic Syntax of CSS Media Queries

Here’s how media queries are structured:

@media (max-width: 768px) {
    /* Styles for screens smaller than 768px */
}

max-width: Applies styles when the screen width is equal to or less than the specified value.
min-width: Applies styles to screens equal to or larger than the specified size.

Examples of CSS Media Queries

Example 1: Mobile-first Design

Design for mobile screens first, then larger devices:

/* Mobile-first styles */
body {
    background-color: lightblue;
}

/* Tablet and desktop screens */
@media (min-width: 768px) {
    body {
        background-color: white;
    }
}

Common Breakpoints for Responsive Design

Breakpoints define when your layout should change. Common examples include:

Mobile: 480px and below
Tablet: 768px to 1024px
Desktop: Above 1024px

Example:

/* Mobile styles */
@media (max-width: 576px) {
    .container {
        padding: 10px;
    }
}

/* Tablet styles */
@media (min-width: 768px) and (max-width: 1024px) {
    .container {
        padding: 20px;
    }
}

/* Desktop styles */
@media (min-width: 1025px) {
    .container {
        padding: 40px;
    }
}

Combining Conditions

You can combine multiple conditions in a media query:

@media (min-width: 768px) and (orientation: landscape) {
    .sidebar {
        display: none;
    }
}

This applies styles only if the screen is at least 768px wide and in landscape mode.

Media Types in Media Queries

You can also specify media types like screen, print, or speech:

/* Styles for print */
@media print {
    body {
        font-size: 12pt;
    }
}

Orientation in Media Queries

Adjust layout based on device orientation:

/* Portrait orientation */
@media (orientation: portrait) {
    body {
        background-color: pink;
    }
}

/* Landscape orientation */
@media (orientation: landscape) {
    body {
        background-color: yellow;
    }
}

Practical Example: Responsive Navigation Menu

Here’s how to make a simple responsive menu:

HTML:

<nav class="menu">
    <ul>
        <li>Home</li>
        <li>About</li>
        <li>Contact</li>
    </ul>
</nav>

CSS:

.menu ul {
    display: flex;
}

@media (max-width: 600px) {
    .menu ul {
        flex-direction: column;
    }
}

Tips for Effective Use of Media Queries

Start with mobile-first approach and add styles for larger screens.
Avoid too many breakpoints to keep your CSS clean and manageable.
Always test your designs on real devices and different screen sizes.
