What is the difference between bootstrap.min.css and bootstrap.css?

Question

What should I use between bootstrap.min.css or bootstrap.css?

I am confused between the two files because bootstrap.css is readable i.e

Answer 1

They have exactly the same function, but the .min.css version has been minified, meaning all whitespace has been removed to reduce file size and increase speed.

The normal .css is better for development if you want to edit and play around with the content, but if you are definitely not going to modify the file, use the .min.css for slightly better performance.
