WordPress Media Queries
Introduction
Media queries are a powerful CSS feature that allow you to apply different styles based on the characteristics of a user's device, most commonly the viewport width. In WordPress development, media queries play a crucial role in creating responsive websites that look great on all devices, from mobile phones to large desktop screens.
This guide will help you understand how to implement and work with media queries in WordPress themes and plugins, allowing you to create truly responsive WordPress websites.
Understanding Media Queries in WordPress
Media queries are not specific to WordPress; they are a standard CSS3 feature. However, WordPress themes and plugins use media queries extensively to ensure sites display correctly on various devices.
A basic media query looks like this:
@media screen and (max-width: 768px) {
/* CSS rules go here */
.my-element {
width: 100%;
}
}
This query applies the CSS rules inside the block only when the screen width is 768 pixels or less.
How WordPress Uses Media Queries
WordPress, especially its default themes, implements media queries to create responsive layouts. Let's look at how WordPress uses media queries:
1. Default WordPress Theme Implementation
WordPress default themes (like Twenty Twenty-Three) include media queries to handle different screen sizes. Here's a simplified example of how Twenty Twenty-One implements media queries:
/* Base styles for mobile */
.site-header {
padding: 1rem;
}
/* Tablet styles */
@media (min-width: 768px) {
.site-header {
padding: 2rem;
}
}
/* Desktop styles */
@media (min-width: 1024px) {
.site-header {
padding: 3rem;
display: flex;
justify-content: space-between;
}
}
2. WordPress Admin Dashboard
WordPress also uses media queries for its admin dashboard to ensure it works well on different devices:
/* Example from WordPress core files */
@media screen and (max-width: 782px) {
#wpadminbar .quicklinks li > ul {
position: relative;
left: 0;
}
#wpadminbar .ab-top-menu > .menupop > .ab-sub-wrapper {
position: relative;
left: auto;
right: auto;
}
}
Including Media Queries in Your WordPress Theme
1. Adding Media Queries to style.css
The most straightforward way to add media queries is by incorporating them into your theme's style.css file:
/* style.css */
/* Base styles first (mobile first approach) */
.content-area {
width: 100%;
padding: 10px;
}
/* Tablet styles */
@media (min-width: 768px) {
.content-area {
padding: 20px;
}
}
/* Desktop styles */
@media (min-width: 1024px) {
.content-area {
width: 70%;
float: left;
}
.sidebar {
width: 25%;
float: right;
}
}
2. Enqueuing Separate Responsive Stylesheets
For better organization, you can create separate CSS files for different breakpoints and enqueue them with WordPress:
function theme_responsive_styles() {
// Base stylesheet
wp_enqueue_style('theme-style', get_stylesheet_uri());
// Tablet stylesheet
wp_enqueue_style(
'theme-tablet',
get_template_directory_uri() . '/css/tablet.css',
array('theme-style'),
'1.0',
'all and (min-width: 768px) and (max-width: 1023px)'
);
// Desktop stylesheet
wp_enqueue_style(
'theme-desktop',
get_template_directory_uri() . '/css/desktop.css',
array('theme-style'),
'1.0',
'all and (min-width: 1024px)'
);
}
add_action('wp_enqueue_scripts', 'theme_responsive_styles');
This approach keeps your CSS files smaller and more maintainable.
Best Practices for WordPress Media Queries
1. Mobile-First Approach
Start with styles for small screens as your base, then use media queries to enhance the layout for larger screens:
/* Base styles for mobile */
.content {
padding: 1rem;
}
/* Enhance for larger screens */
@media (min-width: 768px) {
.content {
padding: 2rem;
max-width: 750px;
margin: 0 auto;
}
}
2. Consistent Breakpoints
Maintain consistent breakpoints throughout your theme:
/* Common breakpoints */
@media (min-width: 576px) { /* Small devices */ }
@media (min-width: 768px) { /* Medium devices */ }
@media (min-width: 992px) { /* Large devices */ }
@media (min-width: 1200px) { /* Extra large devices */ }
3. Using WordPress Admin-Specific Media Queries
When creating admin-side styles, consider the WordPress dashboard's built-in responsive behavior:
/* Custom admin styles */
.my-admin-component {
width: 50%;
}
/* Match WordPress admin breakpoints */
@media screen and (max-width: 782px) {
.my-admin-component {
width: 100%;
}
}
Practical Example: Creating a Responsive WordPress Menu
Let's create a responsive menu for a WordPress theme:
Step 1: HTML Structure in your theme's header.php
<nav class="main-navigation">
<button class="menu-toggle" aria-controls="primary-menu" aria-expanded="false">
<?php esc_html_e('Menu', 'my-theme'); ?>
</button>
<?php
wp_nav_menu(array(
'theme_location' => 'menu-1',
'menu_id' => 'primary-menu',
));
?>
</nav>
Step 2: CSS with Media Queries
/* Mobile styles (base) */
.main-navigation {
position: relative;
}
.menu-toggle {
display: block;
padding: 10px;
background: #333;
color: white;
border: none;
cursor: pointer;
}
#primary-menu {
display: none;
list-style: none;
margin: 0;
padding: 0;
}
#primary-menu.toggled {
display: block;
}
#primary-menu li {
border-bottom: 1px solid #eee;
}
#primary-menu a {
display: block;
padding: 10px;
text-decoration: none;
}
/* Desktop styles */
@media screen and (min-width: 768px) {
.menu-toggle {
display: none;
}
#primary-menu {
display: flex;
flex-wrap: wrap;
}
#primary-menu li {
border: none;
margin-right: 20px;
}
}
Step 3: JavaScript to toggle the mobile menu
(function() {
const menuToggle = document.querySelector('.menu-toggle');
const primaryMenu = document.getElementById('primary-menu');
if (menuToggle) {
menuToggle.addEventListener('click', function() {
primaryMenu.classList.toggle('toggled');
const expanded = menuToggle.getAttribute('aria-expanded') === 'true' || false;
menuToggle.setAttribute('aria-expanded', !expanded);
});
}
})();
Step 4: Enqueue the JavaScript in functions.php
function my_theme_scripts() {
wp_enqueue_script(
'my-theme-navigation',
get_template_directory_uri() . '/js/navigation.js',
array(),
'1.0',
true
);
}
add_action('wp_enqueue_scripts', 'my_theme_scripts');
Advanced Media Queries in WordPress
Feature Queries
Modern CSS allows combining media queries with feature detection:
@supports (display: grid) and (max-width: 768px) {
.content {
display: grid;
grid-template-columns: repeat(auto-fill, minmax(300px, 1fr));
}
}
Print Media Queries
Optimize your WordPress content for printing:
@media print {
header, footer, sidebar, .comments-area, .navigation {
display: none !important;
}
body, .content-area {
width: 100% !important;
margin: 0 !important;
padding: 0 !important;
}
a::after {
content: " (" attr(href) ")";
}
}
Device-Specific Media Queries
Target specific devices with precise media queries:
/* iPads and Tablets */
@media only screen and (min-device-width: 768px) and (max-device-width: 1024px) {
/* iPad/tablet specific styles */
}
/* Retina displays */
@media only screen and (-webkit-min-device-pixel-ratio: 2),
only screen and (min-resolution: 192dpi) {
/* Retina-specific styles */
.logo {
background-image: url('[email protected]');
}
}
Using Media Queries with WordPress Blocks
With the block editor (Gutenberg), you can add responsive styles to custom blocks:
/* Block editor styles */
.wp-block-my-custom-block {
padding: 1rem;
}
@media (min-width: 768px) {
.wp-block-my-custom-block {
padding: 2rem;
display: flex;
}
}
To register these styles with your custom block:
function register_my_custom_block() {
wp_register_style(
'my-custom-block-style',
plugins_url('style.css', __FILE__),
array(),
filemtime(plugin_dir_path(__FILE__) . 'style.css')
);
register_block_type('my-namespace/my-custom-block', array(
'style' => 'my-custom-block-style',
'editor_style' => 'my-custom-block-editor-style',
// Other block properties
));
}
add_action('init', 'register_my_custom_block');
Debugging Media Queries in WordPress
Here's a helpful technique to visualize your breakpoints during development:
/* Add this to your theme's style.css during development */
body::after {
content: "Mobile view (less than 576px)";
position: fixed;
bottom: 0;
left: 0;
right: 0;
z-index: 9999;
background: rgba(0,0,0,0.7);
color: white;
padding: 5px;
text-align: center;
font-size: 12px;
}
@media (min-width: 576px) {
body::after {
content: "Small devices (576px and up)";
background: rgba(0,0,200,0.7);
}
}
@media (min-width: 768px) {
body::after {
content: "Medium devices (768px and up)";
background: rgba(0,200,0,0.7);
}
}
@media (min-width: 992px) {
body::after {
content: "Large devices (992px and up)";
background: rgba(200,0,0,0.7);
}
}
@media (min-width: 1200px) {
body::after {
content: "Extra large devices (1200px and up)";
background: rgba(200,0,200,0.7);
}
}
Just remember to remove this before pushing to production!
