Can this be done using LESS?
Yes.
The code you provided works in LESS. The & combinator
works the same.
In the end, the selectors generated for:
div.subnav {
...
html.js & {
...
}
}
will be:
div.subnav {
...
}
html.js div.subnav {
...
}

Example scenario: I would like to hide a sub-navigation menu if the user has javascript enabled so that it can be revealed on a click of a navigation link further up in the nav hierarchy. Modernizr adds a class 'js' to the html tag if javascript is enabled so I can use that for detection.
In SASS I can do something like this:
div.subnav{ display: block; html.js & { display: none; } }
Can this be done using LESS? Can I target a parent from within another rule?
