Responsive

Reflex apps can be made responsive to look good on mobile, tablet, and desktop.

You can pass a list of values to any style property to specify its value on different screen sizes.

The text will change color based on your screen size. If you are on desktop, try changing the size of your browser window to see the color change.

Responsive values can also be specified using rx.breakpoints. Each size maps to a corresponding key, the value of which will be applied when the screen size is greater than or equal to the named breakpoint.

Custom breakpoints in CSS units can be mapped to values per component using a dictionary instead of named parameters.

For the Radix UI components' fields that supports responsive value, you can also use rx.breakpoints (note that custom breakpoints and list syntax aren't supported).

The default breakpoints are shown below.

You can customize them using the style property.

A common use case for responsive is to show different components based on the screen size.

Reflex provides useful helper components for this.

You can specify the breakpoints to use for the responsive components by using the display style property.
