元素函数可用
set和show规则自定义样式。Arranges content and spacing horizontally or vertically.
The stack places a list of items along an axis, with optional spacing between each item.
Example
#stack(
dir: ttb,
rect(width: 40pt),
rect(width: 120pt),
rect(width: 90pt),
)

set规则设置参数，更改后续调用时的默认值。The direction along which the items are stacked. Possible values are:
ltr: Left to right.rtl: Right to left.ttb: Top to bottom.btt: Bottom to top.
You can use the start and end methods to obtain the initial and
final points (respectively) of a direction, as alignment. You can also
use the axis method to determine whether a direction is
"horizontal" or "vertical". The inv method returns a
direction's inverse direction.
For example, ttb.start() is top, ttb.end() is bottom,
ttb.axis() is "vertical" and ttb.inv() is equal to btt.
默认值：ttb
Spacing to insert between items where no explicit spacing was provided.
默认值：none
