We probably don't need a "_my_projects.scss". A general "_projects.scss" should suffice for all project type things. 

Also you probably need an overarching '.pd-projects' class selector and use something like:
````
.pd-projects {
    //styles specific to projects
    &.inactive { //could potentally also use .active instead of &.active depending on how HTML is structure
        //override styles specific to projects
    }
}
````
