SASS Structure and custom CSS


I am fairly new to SASS and i was wondering the best way to structure the SASS files? If i have lots of CSS, where do i put it?

/scss ( < should everything be in here?
or /www/css/ < or here?

What do you do for multiple css files?

For example if i had messages.css, grid.css, home.css etc etc, where would i put these and how would i structure this and setup with SASS and the gulp file?

Sorry if this sounds newbie question


Usually you create a main file (e.g. app.scss) which imports other files prefixed with an underscore (Sass partials) using the @import directive.
