Defines a breakpoint plugin manager to deal with breakpoints.
Extension can define breakpoints in a EXTENSION_NAME.breakpoints.yml file contained in the extension's base directory. Each breakpoint has the following structure:
MACHINE_NAME:
label: STRING
mediaQuery: STRING
weight: INTEGER
multipliers:
- STRING
For example:
bartik.mobile:
label: mobile
mediaQuery: '(min-width: 0px)'
weight: 0
multipliers:
- 1x
- 2x
Optionally a breakpoint can provide a group key. By default an extensions breakpoints will be placed in a group labelled with the extension name.
