In my opinion selecting something based on it's layout is oftentimes a dangerous pattern, you are basically tying the UI layout with the logic. People can overuse these cool selectors. I've personally worked on a website where the frontend part was a spaghetti mess with the half of the source code occupied by selector names. Some files have over 5000 lines of code. It would be far less pain to maintain and implement features if the website used some framework like angular.
