How does browsersync monitor multiple html files?

Question

I’ve been working on it for a long time, please give me some advice

Answer 1

// --files path is relative to the project (directory) where the command is run
browser-sync start --server --files "css/*.css, *.html"

// If your file hierarchy is relatively deep, you may consider using ** (indicating any directory) to match any .css or .html file in any directory.
browser-sync start --server --files "**/*.css, **/*.html"
