On my website, I have decided to incorporate high-resolution images as the background for the body. However, when I use
document.body.style.backgroundImage = "url('URL OF PICTURE')";To load an image, you can utilize the Image() method and wait for the onload event before inserting it into the document once it has loaded.
let picture = new Image();
picture.onload = function(){
document.querySelector('body').style.backgroundImage = "url('" + picture.src + "')";
};
picture.src = 'imageURL.jpg';
To easily accomplish this task, you can choose to initially hide the body content and reveal it once the page has finished loading.
body { visibility: hidden; }
window.addEventListener("load", function displayBody() {
// Remove the load event listener
window.removeEventListener("load", displayBody, false);
// Display the body by setting its visibility to "visible"
document.body.style.visibility = "visible";
});
