手写笔 - 如何实现参数化转换

Question

我有一个里面有N li ul。我想将每个li旋转 360/N 度，以便它们形成一个轮子。

代码笔

我已经在 Stylus 中尝试了许多语法来实现这一点，但我总是收到相同的错误：

预期的"标识"或"字符串"，得到"单元 360">

例如：

n=8
for i in (1..n)
    li:nth-child({i})
        transform rotate( {360/i}deg ) // expected "ident" or "string", got "unit 360"

或

n=8
for i in (1..n)
    li:nth-child({i})
        transform rotate( {360/i + 'deg'} ) // expected "ident" or "string", got "unit 360"

或

n=8
rotation = 0deg
for i in (1..n)
    li:nth-child({i})
        transform rotate( rotation )
    rotation = rotation + {360/i} + "deg" // expected "ident" or "string", got "unit 360"

或

n=8
rotation = 0deg
for i in (1..n)
    li:nth-child({i})
        transform rotate( rotation )
    rotation += {360/i + "deg"} // expected "ident" or "string", got "unit 360"

有谁知道正确的语法？

Answer 1

它更容易：

n=8
for i in (1..n)
    li:nth-child({i})
        transform rotate(360/i deg)
