Hi Brad,

If you would like to bring other .scss files into your theme, you could use the @import directive - which works similar to how the {% include %} feature works with liquid.

First, create your separate .scss file with a name that leads with an underscore "_" and ends in ".scss", such as "_added_styles.scss"

Then, in your theme file (or other .scss file you would like to bring your code into), you would use the call

@import "added_styles";

Notice that to call the .scss file I had created, I did not include the leading underscore or the ".scss" extension (otherwise your file won't be imported correctly). 

A more complete walkthrough of the @import directive, as well as information on partials, can be found online here.
