I'm trying to make a game using HTML, CSS and Java

Question

I inserted <bottom id="start" onclick=start( )>START</bottom> but when I try to open the game it says that start is not a function. what must I do?

Answer 1

Go through this checklist:

Are you using JavaScript?
Did you link the script?
Can the JavaScript run separately? (If so, it's an HTML problem; otherwise, it's a JavaScript problem)
Is your syntax good?

Answer 2

tell me, if I wrote something in HTML, must I also write something in CSS and Java?

Answer 3

yes if it says start is not a function there is error in making of function start()
function start(){
you can also make by this
}
check for this on your code

Answer 4

and do you have a function named start() in your JS code? The name id="start " in tag is only an identificator of button, nothing for running.
