I prefer using lobotomized owls *+*

this makes your code less optimized, so in performance terms it's an issue and must be avoided

How so? What's less performant about *+* compared to the other ways you could express it?

• selects all elements so it parses multiple times to the CSSOM, as more specific a selector is, more performance when applying it. li+li will apply to all li parent elements of another li, where + will apply to any element being parent of whatever other element.
