I know the feeling, this is really annoying. I found a quick way of doing it tho.
HTML
SCSS
CSS is pointed towards to first child of div "mainmenu"
with the > class "subnav"
.mainmenu{
& > .subnav{
// Child Selector SCSS HERE
}
}
@thgaskell, you have proved me wrong :) My code works fine and I lost 6KB of my Minified code! I have updated the code as how the comment below was informed.
