How to fix regular expression in JS?

Question

JavaScript

regexr.com/3br05
product-spec is in the first line
product-minicard in the last line
And if you remove line breaks, everything works regexr.com/3br08
Why? I have the m modifier! Well, how to fix it?

Answer 1

product-spec([\S\W]*?)product-minicard

Answer 2

You answered your own question - there are hyphens in the line. You need something like this: The m
modifier affects the work of ^ and $ (in other languages, the behavior may be different), read about it in the documentation.
