How to Implement Loading Image with CSS

I have customized the CSS code below to style a div element that showcases a responsive image.

.my-img-container {
  position: relative;
  &:before {
    display: block;
    content: " ";
    background: url("https://lorempixel.com/300/160/") no-repeat;
    background-size: 100% 100%;
    width: 100% !important;
    padding-top: 56.25%;
  }
  >img {
    position: absolute;
    top: 0;
    left: 0;
    right: 0;
    bottom: 0;
    width: 100% !important;
    height: 100% !important;
  }
}
<div class="my-img-container">
  <img srcset="https://lorempixel.com/540/304 540w, https://lorempixel.com/960/540 960w" sizes="(min-width: 576px) 540px, 100vw" src="https://lorempixel.com/300/160">
</div>

I am attempting to show an image in the background while the responsive image loads using the content in the CSS, but it's not functioning as expected. Any thoughts on why this may be happening?

Answer №1

Why bother loading a smaller image for a loader when you can simply rotate a pseudo element instead?

This method allows for quicker loading without the need for an additional server call.

.my-img-container {
  position: relative;
  padding-top: 50%;
}
.my-img-container:before {
  content: " ";
  position: absolute;
  top: 50%;
  left: 50%;
  width: 80px;
  height: 80px;
  border: 2px solid red;
  border-color: transparent red transparent red;
  border-radius: 50%;
  animation: loader 1s linear infinite;
}
.my-img-container > img {
  position: absolute;
  top: 0;
  left: 0;
  right: 0;
  bottom: 0;
  width: 100% !important;
  height: 100% !important;
}
@keyframes loader {
  0% {
    transform: translate(-50%,-50%) rotate(0deg);
  }
  100% {
    transform: translate(-50%,-50%) rotate(360deg);
  }
}
<div class="my-img-container">
  <img src="https://picsum.photos/600/300">
</div>

If you want to add a spinner as a background to an image, you can do so by using the following CSS:

html,
body {
  height: 100%;
  margin: 0;
}

img {
  display: block;
  top: 0;
  left: 0;
  right: 0;
  bottom: 0;
  width: 100%;
  height: 100%;
  background: url(https://upload.wikimedia.org/wikipedia/commons/b/b1/Loading_icon.gif) no-repeat center;
}
<img srcset="https://picsum.photos/540/304 540w, https://picsum.photos/960/540 960w" sizes="(min-width: 576px) 540px, 100vw" src="https://picsum.photos/300/160">
