SCSS (sass) calculation: #{}
提问by matt
i'm quite confused at the moment when it comes to calculating a font-size
在计算字体大小时，我现在很困惑
this is the normal calculation I already use.
这是我已经使用的正常计算。
font-size: #{($font-size*0.7) / $em}em
font-size: #{($font-size*0.7) / $em}em
What I wanna do now is divide an entire statement like the one above with another one …?sounds complicated I know.
我现在想要做的是将一个完整的陈述（如上面的陈述）与另一个陈述分开......？我知道听起来很复杂。
So I have #{($font-size*0.7) / $em}And I have #{($font-size*0.8125) / $em}
所以我有#{($font-size*0.7) / $em}我有#{($font-size*0.8125) / $em}
I want to devide those two values now …
我现在想分开这两个值......
So font-size: #{($font-size*0.7) / $em} / #{($font-size*0.8125) / $em}em.
所以font-size: #{($font-size*0.7) / $em} / #{($font-size*0.8125) / $em}em。
But that doesn't work. Any idea how I do a calculation like that with SASS?
但这不起作用。知道我如何用 SASS 做这样的计算吗？

Try:
尝试：
font-size: #{(($font-size*0.7) / $em) / (($font-size*0.8125) / $em)}em
The interpolation back into a string #{...}should be the last thing done after the calculations.
插回字符串#{...}应该是计算后做的最后一件事。

ScottS answer appears to be technicallycorrect, but why do you even need such a complex expression in the first place? Expressed as a fraction, this can be simplified to
ScottS 的答案在技术上似乎是正确的，但是为什么您首先需要如此复杂的表达式？表示为分数，这可以简化为
($font-size * 0.7 / $em) / ($font-size * 0.8125 / $em) = 0.7 / 0.8125
And your final expression would be
你的最终表达是
font-size: #{(0.7/0.8125)}em
...wouldn't it?
……不会吧？
