There are 7 CSS breakpoints to provide you maximum control over the responsive behavior of the layout of your app.

These breakpoint values are used throughout React UI, in components, or in helper classes. You can reuse them in your own CSS and components to create a seamless experience for your users.

** ⚠️ Consider CSS breakpoints as read-only: because CSS custom properties cannot be used inside media queries (media query is not a CSS property), changing their values will have no effect. If you need to adjust the breakpoint values, you must override the $values SCSS map defined in styles/settings/_breakpoints.scss.
