@media screen and (max-width: 767px) { ... }@media screen and (min-width: 768px) and (max-width: 1023px) { ... }@media screen and (min-width: 1024px) { ... }@media screen and (max-width: 767px) { ... }@media screen and (min-width: 768px) and (max-width: 1023px) { ... }@media screen and (min-width: 1024px) { ... }Copy the generated CSS and paste it into your stylesheet. Each @media block wraps the styles you want to apply at that breakpoint. Use min-width for mobile-first (styles apply from that width up) and max-width for desktop-first (styles apply up to that width).

Common Use Cases for Media Query Builder
Practical applications for responsive CSS breakpoint generation
Responsive Web Design
Use our media query builder to define breakpoints for mobile, tablet, and desktop layouts. Generate min-width and max-width rules that adapt your layout, typography, and spacing to any screen size without writing a single line of CSS by hand.
Framework Breakpoint Setup
Load Bootstrap 5 or Tailwind CSS presets in one click to generate the exact breakpoints used by those frameworks. Customize the values to match your design system and copy the CSS directly into your project.
Mobile-First Development
Build mobile-first stylesheets by generating min-width media queries that progressively enhance the layout as the viewport grows. Our media query builder makes it easy to visualize the breakpoint range on the ruler before writing any code.
Tablet and Orientation Targeting
Target specific device orientations with portrait and landscape media queries. Use the range query type to isolate tablet-sized viewports between two breakpoints, ensuring styles apply only to the intended device class.
Print Stylesheet Generation
Switch the media type to "print" to generate print-specific media queries. Control which styles apply when users print your page — hide navigation, adjust font sizes, and remove backgrounds for clean printed output.
Design System Documentation
Document your design system breakpoints by generating a complete CSS file with named breakpoints and comments. Download the .css file and share it with your team as a reference for consistent responsive behavior across all components.

What is a CSS Media Query?
A CSS media query is a conditional rule that applies styles only when the browser or device matches a specified condition — such as a minimum viewport width, maximum screen height, or device orientation. The syntax is @media screen and (min-width: 768px) { ... }. Media queries are the foundation of responsive web design, allowing a single stylesheet to adapt layouts, typography, and spacing to any screen size. Our media query builder generates these rules visually so you can configure breakpoints without memorizing syntax.
How Our Media Query Builder Works
- Add Your Breakpoints:Click "Add Breakpoint" or load a preset (Bootstrap 5, Tailwind CSS, Mobile First) to populate a set of named breakpoints. Each breakpoint has its own configuration panel.
- Configure Each Breakpoint: Choose the media type (screen, print, all), query type (min-width, max-width, range, height, orientation, or custom), enter your values, and select the unit (px, em, rem). The generated query updates live as you type.
- Copy or Download the CSS: The media query builder outputs the complete CSS for all breakpoints. Copy individual queries or download the full stylesheet as a
.cssfile.
What Gets Generated
- min-width queries: Apply styles from a minimum viewport width upward — the standard approach for mobile-first responsive design.
- max-width queries: Apply styles up to a maximum viewport width — used in desktop-first approaches to override styles for smaller screens.
- Range queries (min + max): Combine min-width and max-width to target a specific viewport range, such as tablet-only styles between 768px and 1023px.
- Orientation queries: Target portrait or landscape orientation independently of viewport size — useful for tablet layout adjustments.
px vs em vs rem in Media Queries
The unit you choose for media query breakpoints affects how they respond to user preferences. px breakpoints are absolute and do not scale with browser font size settings. embreakpoints are relative to the browser's base font size (typically 16px), so 48em equals 768px at the default size but scales if the user changes their browser font size. rem behaves identically to em in media queries (both reference the browser default, not the root element). Many accessibility-focused developers prefer em or rem breakpoints because they respect user font size preferences, ensuring layouts reflow correctly for users who increase their default font size.

Frequently Asked Questions About Media Query Builder
Common questions about CSS media queries, breakpoints, and responsive design
A media query builder is a visual tool that generates CSS @media rules from form inputs — no need to memorize syntax. Our media query builder runs entirely in your browser, lets you configure min-width, max-width, range, height, orientation, and custom conditions, and outputs copy-ready CSS instantly.
A min-width media query applies styles when the viewport is at least the specified width — this is the mobile-first approach, where base styles target small screens and breakpoints progressively enhance for larger ones. A max-width media query applies styles when the viewport is at most the specified width — this is the desktop-first approach, where base styles target large screens and breakpoints override for smaller ones. Most modern frameworks like Tailwind CSS and Bootstrap use min-width (mobile-first).
All three work, but they behave differently. px breakpoints are absolute and ignore browser font size settings. em and rem breakpoints scale with the browser's base font size, so they reflow correctly when users increase their default font size for accessibility. Many accessibility-focused developers prefer em breakpoints. At the default 16px browser font size, 48em = 768px, 64em = 1024px, and 80em = 1280px.
Absolutely. All media query generation happens locally in your browser using JavaScript. Your CSS code and breakpoint configurations are never sent to any server, stored, or logged. Your data stays completely private on your device.
Yes! Our media query builder is 100% free with no signup, no account, and no usage limits. Build responsive breakpoints for any project as many times as you need — completely free, forever.
Bootstrap 5 uses six breakpoints: xs (< 576px), sm (≥ 576px), md (≥ 768px), lg (≥ 992px), xl (≥ 1200px), and xxl (≥ 1400px). All are min-width based except xs, which uses max-width. Load the Bootstrap 5 preset in our media query builder to generate all six breakpoints instantly.
Tailwind CSS uses five default breakpoints: sm (≥ 640px), md (≥ 768px), lg (≥ 1024px), xl (≥ 1280px), and 2xl (≥ 1536px). All are min-width based, following the mobile-first approach. Load the Tailwind CSS preset in our media query builder to generate all five breakpoints with one click.
Yes. Select "orientation" as the query type in our media query builder and choose either "landscape" or "portrait". This generates a rule like @media screen and (orientation: landscape) that applies styles based on whether the device is held horizontally or vertically, regardless of the exact viewport dimensions.
Select "min-width + max-width" as the query type, enter your minimum value (e.g. 768) and maximum value (e.g. 1023), and choose px as the unit. This generates @media screen and (min-width: 768px) and (max-width: 1023px), which applies styles only when the viewport is between those two widths — targeting tablet-sized screens while excluding mobile and desktop.
