I don't know why (1) less than two tags, (2) no example code, (3) poorly formatted was indicator that OP doesn't write a good question. Point (1) likely wasn't valid indicator because many good question has only single tag. We can edit to include relevant tags tough. Point (2) wasn't a bit confused me because we aren't SO, and we need configuration instead code. Point (3) can't be fixed by edit though. Maybe OP doesn't know how to write in Markdown. Single edit will help OP familiarize himself with formatting

So how do I apply your JavaScript code into a browser? Step by step maybe?

+1. Why should we putting work on mods when we can let the system do their jobs? It reminds me to featured meta discussion How to find and clean up bad questions

Ah...Yes. Looks like this question was subset of question with no-possible-answer. And we should treat this type of question was same as above.
