I want to know how can I change my background on Id load. Right now the background is set to a colour for the preloader. I have figured out how I can hide the loader on body load but someone help me on how to change my background to a picture. Also eve when the loader is present the elements of the body popup so any solution to hide that? The background link is in the background 1 id.

function hidespinner() {
  document.getElementById('spinner').style.display = 'none';
  document.getElementById('heading').style.display = 'none';
  document.getElementById('background1').style.display.backgroundImage = 'url(https://s28.postimg.org/rbexyjiil/IFBAKGROUND1.jpg)';

<body onload="hidespinner()">
  <h1 id="heading"><i class="fa fa-plane"></i> v<strong>Crew</strong></h1>
      <div id="spinner">

        <div class="inner"></div>

      Hello Is the spinner on?
</body>

Please see that even the current code is copyrighted. I would also like to add this loader which I made to the page so can anyone suggest something on how to add it or add it to the webpage and give me the code.

function hideloader() {
  document.getElementById("loading").style.display = "none";
}
@import url('https://fonts.googleapis.com/css?family=Spirax');
@import url('https://fonts.googleapis.com/css?family=Indie+Flower|Spirax');

body {
  background-color: #58e8f8;
}

.silly {
  color: white;
  text-align: center;
  font-family: "Indie Flower"
}

.spinner {
  width: 80px;
  height: 80px;
  position: fixed;
  left: 0;
  right: 0;
  top: 0;
  bottom: 0;
  margin: auto;
}

.double-bounce1,
.double-bounce2 {
  width: 100%;
  height: 100%;
  border-radius: 50%;
  background-color: white;
  opacity: 0.6;
  position: absolute;
  top: 0;
  left: 0;
  -webkit-animation: sk-bounce 2.0s infinite ease-in-out;
  animation: sk-bounce 2.0s infinite ease-in-out;
}

.double-bounce2 {
  -webkit-animation-delay: -2.0s;
  animation-delay: -1.0s;
}

@-webkit-keyframes sk-bounce {
  0%,
  100% {
    -webkit-transform: scale(0.0)
  }
  50% {
    -webkit-transform: scale(1.0)
  }
}

@keyframes sk-bounce {
  0%,
  100% {
    transform: scale(0.0);
    -webkit-transform: scale(0.0);
  }
  50% {
    transform: scale(1.0);
    -webkit-transform: scale(1.0);
  }
<title>Page Title</title>
<script type="text/javascript" src="https://gc.kis.v2.scr.kaspersky-labs.com/88CE1C4C-84C0-9E49-A763-9D3DCEC43907/main.js" charset="UTF-8"></script>

<body onload="hideloader">
  <h1 class="silly"> vCrew </h1>

  <div id="loading" class="spinner">
    <div class="double-bounce1"></div>
    <div class="double-bounce2"></div>
  </div>
</body>

Would this work w3schools.com/code/tryit.asp?filename=FEMJIZCDHJBW ?

    You might need to use some Javascript. –  Apr 14 '17 at 06:57
  • I created this in response to another loading-related question: http://stackoverflow.com/a/25253988/1762224 – Mr. Polywhirl Apr 14 '17 at 14:35
  • First of all: `document.getElementById('background1').style.display.backgroundImage = 'url(https://s28.postimg.org/rbexyjiil/IFBAKGROUND1.jpg)'; ` I think the `.display` shouldn't be there. It's a property itself, like `backgroundImage`. – lennyklb Apr 14 '17 at 14:36

You can try adding a loading div on top of your content and hide/show the loading sequence until your data is present.

onReady(function() {
  toggleClass(document.getElementById('page'), 'hidden');
  toggleClass(document.getElementById('loading'), 'hidden');
});

function onReady(callback) {
  var intervalID = window.setInterval(function checkReady() {
    if (document.getElementsByTagName('body')[0] !== undefined) {
      window.clearInterval(intervalID);
      callback.call(this);
    }
  }, 1000);
}

// http://youmightnotneedjquery.com/
function toggleClass(el, className) {
  if (el.classList) el.classList.toggle(className);
  else {
    var classes = el.className.split(' ');
    var existingIndex = classes.indexOf(className);
    if (existingIndex >= 0) classes.splice(existingIndex, 1);
    else classes.push(className);
    el.className = classes.join(' ');
  }
}
body {
  background: #FFF url("http://i.imgur.com/KheAuef.png") top left repeat-x;
  font-family: "Brush Script MT", cursive;
