suggestion for clear style

[goldenbearkin]

if dont support below responsively,

<Row start="xs" end="lg">

why don't make it defaults to "xs" and becomes

<Row start>

Above looks a lot clear, less boilerplate !
now, everytime i need to write

<Row start="xs">

Mmh... Yes maybe it could be useful.

We could consider each prop of this kind as xs when strictly equal to true. It will produce a media query with min-width: 0, so the default.

All properties of this kind:

• start
• center
• end
• top
• middle
• bottom
• around
• between
• first
• last

I dont think that end === true should be interpreted to lg. It does not make sense.
