Good afternoon, dear ones.
I'm having a problem importing the external javascript, (in the Jquery library case)
The files are in the correct folder but when I call through src="" nothing happens.
From this, thank you for your help.
Just as Mr Maurivan said. When we use Bootstrap, we must import the css files and js files.
In the case of js files we must obey the order of precedence of who depends on whom. That in this case Bootstrap depends on JQuery, then it should come first in the loading order.
