JavaScript JavaScript Foundations Variables Basics

A task isn't consistent all the way through, can this be fixed?

Keep doing what it prompts me to do and this error comes up, and I checked and the task that I completed at first is still correct and hasn't reverted back to original file.

<!DOCTYPE html>
<html lang="en">
    <title> JavaScript Foundations: Variables</title>
      html {
        background: #FAFAFA;
        font-family: sans-serif;

    <h1 id="title">JavaScript Foundations</h1>
    <h2>Variables: Basics</h2>

    <div id="container">
      This is a div with the id of "container"
  <script src="myscript.js"></script>
/* JavaScript Foundations: Variables */

var bgColor = "blue";
var textColor = "#FF9933";

var container = document.getElementById();
container.style.background = bgColor;
container.style.color = textColor;

Hi Jason,

The only issue I see with your code is you don't have container specified as the id for getElementById, aside from that there's a minor bug in the code challenge that allows you to put the script tag after the closing body tag but that's not causing any issues.

var container = document.getElementById('container');
