If you can’t target them by id or class, by position? eg. instead of main-st → smith, main-st → second-house

What I generally do is go up the DOM until I find an ancestor element with an id, or in lieu of that a few elements with classes, and then go to the child element I want to target. If need be, a “first”, “last” or “nth” pseudo-class should do the job.
