Reset to default 7

Since LESS processes your styles BEFORE the CSS gets delivered and interpreted by the browser there is no way you can let it do the math after that. The information needed is rendered way later, so you will have to either include a JS to modify the DOM after loading or make JS build the section in the first place.
