Does anyone know if there's a way to interpolate a variable within a variable in Sass?
Can you elaborate?
If what you're asking is "can I use interpolation to build up a variable name?" then the answer is no... but you can use placeholders to do something similar. Check out this small post: http://krasimirtsonev.com/blog/article/SASS-interpolation-in-a-name-of-variable-nest-variables-within-variables
