"""Layout specification
|
||
|
|
|
||
|
|
Defines a layout that can be expressed using CSS. Supports a subset of
|
||
|
|
https://developer.mozilla.org/en-US/docs/Web/CSS/Reference
|
||
|
|
|
||
|
|
When a property is also accessible via a shorthand property, we only
|
||
|
|
expose the shorthand.
|
||
|
|
|
||
|
|
For example:
|
||
|
|
- ``flex-grow``, ``flex-shrink`` and ``flex-basis`` are bound to ``flex``.
|
||
|
|
- ``flex-wrap`` and ``flex-direction`` are bound to ``flex-flow``.
|
||
|
|
- ``margin-[top/bottom/left/right]`` values are bound to ``margin``, etc.
