Front End Web Development Techdegree Student 7,841 PointsI'm missing the benefit of &
What's the benefit of the &?
In the example below, why not just say .intro p (as opposed to .intro &)? It seems like it's an unnecessary layer of complexity.
p {
margin-bottom: 1.25em;
.intro & {
font-size: 1.2em;
}
}

p .intro {
margin-bottom: 1.25em;
font-size: 1.2em;
}
In simple code, advanced tricks like this don't really seem logical, but for example...
.button {
&:visited { }
&:hover { }
&:active { }
}
compiles to
.button:visited { }
.button:hover { }
.button:active { }
which is not the same as
.button .hover {
}
check out the link here for more visual and in depth explanation. It really is a helpful tool to save you time.
