In a simple HTML,CSS and JavaScript game, I replaced (in the CSS)
background-color:green;
with
background-image: url(flappybird.png);
and I also tried: (and with single quotations)
background-image: url("flappybird.png");
but the image is not being displayed on the page. I have tried adding the semi colon and also speech marks.
I also tried adding z-index=10000000 to character, but that didn't help.
Can anyone tell me what I am doing wrong. I can confirm that the image is named correctly flappybird.png and is in the root folder.
var character = document.getElementById("character");
var enemy = document.getElementById("enemy");
function jump(){
    if(character.classlist!="animate"){
    character.classList.add("animate");
    }
    setTimeout(function(){
        character.classList.remove("animate");
    },500);
    
}
//right movement
function right() {
  var leftVal =  parseInt(window.getComputedStyle(character).getPropertyValue("left"))
  character.style.left = (leftVal + 30) + "px";
}
//left movement
function left() {
  var leftVal =  parseInt(window.getComputedStyle(character).getPropertyValue("left"))
  character.style.left = (leftVal - 30) + "px";
}
var checkDead =setInterval(function(){
    var characterTop = parseInt(window.getComputedStyle(character).getPropertyValue("top"));
    var enemyLeft = parseInt(window.getComputedStyle(enemy).getPropertyValue("left"));
    //ADD VARIABLE TO FIND CHARACTER RIGHT -if it collides with enemy left, you are out
    //remove the condition that the enemy has to be in the first 30 pixels of the game (left side)
    var characterRight =parseInt(window.getComputedStyle(character).getPropertyValue("right"));
    
 
    
    if(
        characterTop==enemyLeft //have tried characterRight==enemyLeft didn't work
    )
    {
        enemy.style.animation="none"; //remove the animation
        enemy.style.display="none";
        alert("Game Over");
        
    } 
},10);
//left
addEventListener("keydown", function(e) {
    if(e.keyCode == 37) left()
})
//jump (up)
addEventListener("keydown", function(e) {
  if (e.keyCode === 38) {
    jump()
  }

    right()

If I was to use an image, it should also resize, and I note the width and height don't work as expected in this situation. Could that also be addressed in any answers.
The below code thus uncovers the image if I adjust the width and height, but does not resize correctly, which I cannot figure out.
#character{
    width:60px;
    height:50px;
    /*background-color:green;*/
    background-image: url(flappybird.png);
    position:relative;
    top:320px;
    background-size: cover;
    /*animation: jump 300ms */
