direction
The four directions into which content can be laid out.
Possible values are:
ltr
: Left to right.rtl
: Right to left.ttb
: Top to bottom.btt
: Bottom to top.
These values are available globally and also in the direction type's scope, so you can write either of the following two:
#stack(dir: rtl)[A][B][C]
#stack(dir: direction.rtl)[A][B][C]

定义定义这些函数和类型带有附属定义。要访问这种定义,请先写上函数或类型的名称,再加上定义的名称,并用句点在中间分隔。
