Breakpoints
-------
The breakpoints property allows you to apply styles depending on window.innerWidth.

You must indicate the maximum size for which the styles will be applied, that means that the styles will be applied as long as windows.width <= size, where size is a number.
Breakpoints property must have this structure:
`
{
size1: { styles1 },
size2: { styles2 },
...
sizeN: { stylesN }
}
`
you can also use a flexDirection value such as column, column-reverse, row, row-reverse, or a className, in this case, the name of the class cannot be any of the 4 possible values of flexDirection, so, className cannot be any of these column, column-reverse, row or row-reverse.

`
{
size1: 'flexDirection value, for example: column, column-reverse, row or row-reverse',
size2: 'any className except column, column-reverse, row, row-reverse',
...
sizeN: 'column, column-reverse, row, row-reverse or className'
}
`
for example:
`
850: { flexDirection: 'row', backgroundColor: 'green' },
600: 'row-reverse'
}}>
Hello
world!

`
Breakpoints styles are applied cumulatively, for example, for the Column declared above, these will be the styles, depending on window.innerWidth:

window.innerWidth > 850 --> styles = {}

600 < window.innerWidth <= 850 --> styles = { flexDirection: 'row', backgroundColor: 'green' }

window.innerWidth <= 600 --> styles = { flexDirection: 'row-reverse', backgroundColor: 'green' }

You can see this breakpoints` examples in codesandbox.
