Question

Sass

Good day.
Is it possible in SCSS to use & on .class1, .class2 so that we get .class1.subclass, .class2.subclass?
Those. from:

.class1, .class2 {
    &_subclass {
        color: #CCC;
    }
}

after compilation get this:

.class1_subclass, .class2_subclass {
    color: #CCC;
}

Answer 1

If you need a dot, then write a dot =)

.class1, .class2 {
    &.subclass {
        color: #CCC;
    }
}
