CSS Media Query Builder
Build responsive media queries from common width and device conditions.
Responsive breakpoints made simple
Media queries are how a layout responds to screen size, orientation, and preferences, but the syntax is easy to fumble. This builder assembles a valid @media query from common conditions — min/max width, orientation, and device features — so you get it right the first time.
Picking the conditions from controls removes the guesswork around parentheses and units. Set the condition you need and copy the media query wrapper, ready to hold the responsive styles for that breakpoint.
Copy-ready CSS
The CSS is generated live in your browser as you adjust the controls, so there is nothing to install and nothing is uploaded. Copy the ready-to-use declaration straight into your stylesheet, tweak the values to taste, and it will render exactly as it does in the preview here.
