Mixins
Mixins are created using the postcss-mixins plugin.
Breakpoint mixins
There are breakpoint mixins; they are very similar to the Bootstrap mixins.
Breakpoints are defined in theme.json and are read and added to the mixin automatically.
Example usage:
Create a min-width breakpoint
@mixin breakpoint-up sm {
background-color: red;
}
Create a breakpoint between two breakpoints
@mixin breakpoint-between sm, md {
background-color: red;
}
