javascript - Why is a DOM element null?

Saturday, 23 July 2016

I have this simple HTML file:




    



    I am a paragraph tag

    I am an h1 tag

     I am a div tag

And this simple script (test.js):

y=document.getElementById("id");
y.style.color="green";

Why on earth is "y" null? The error I'm getting is

TypeError: y is null

I'm sure this is a simple syntax thing that I'm missing, but I can't for the life of me figure it out! Help!

Post Script: Both the html file and the test.js file are in the same folder.
