Is it compulsory to use bootstrap class name same as it in tutorial ?

Question

can i use my own classes names ? And can i use those bootstrap classes to change the style of my content ?

Answer 1

I recommend using the names that Bootstrap brings, because it is the only acceptable option when you do a real job. But you can always download a file without compiling and changing the names of the classes.

Answer 2

And can i use same bootstrap classes to style the pages (more than bootstrap) style ?
