Question

I don't understand why there's input value= "submit" and input value="send" when the input type is same which is "submit" and
I also don't understand what's the difference between them and
what they do and
I also don't understand what class means here.

Input type="submit" value = "submit"

Input type ="submit" value= "send" class= "submit"

Answer 1

The value is just a attribute to set the name of the button it does nothing, whatever you write in value ,

But the main work of this is summiting the form and sending some data to servers

Even you can write your own name in value attribute, it doesn't matter
