Animating the process of eliminating a background image

Question

Animating the process of eliminating a background image

I am working on a project with a div that has a background-image. The goal is to make the image fade away when a button is clicked, and then fade in again when another button is pressed. The focus is on only fading the background image while keeping the content unaffected.

Any suggestions on how to achieve this effect? I have experimented with jQuery's animate() without success. CSS transitions do not seem to be effective either, as altering the opacity makes all the content transparent as well.

Check out my Fiddle for reference.

Answer №1

If you're looking to fade a background image, one way to achieve this is by placing it in a separate div and applying the fade effect:

$('.fade').on('click', function() {
  $('.background').fadeToggle();
});

.container {
  position: relative;
}
.background {
  position: absolute;
  z-index: -1;
  top: 0;
  left: 0;
  bottom: 0;
  right: 0;
  background: url(http://lorempixel.com/800/800/city/1/) left top no-repeat;
  background-size: cover;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="container">
  <div class="background"></div>
  Lorem ipsum dolor sit amet, consectetur adipiscing elit. Ut id diam ac dolor gravida ultricies. Sed pretium, orci at pharetra placerat, velit mauris posuere mauris, et ornare libero ligula tristique enim. Etiam vitae lobortis erat, ut volutpat ipsum.
  Suspendisse potenti.
</div>
<div class="fade">fade toggle</div>

Update

You can also use a CSS transition to fade to a transparent PNG:

$('.background').click(function() {
    $(this).toggleClass('blank')
})

.background {
  width: 400px;
  height: 400px;
  background: url(http://lorempixel.com/400/400/city/1/) left top no-repeat;
  transition: background-image 0.5s;
}

.background.blank {
  background: url(http://i.imgur.com/qkeOXbO.png) left top no-repeat;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="background">

If you want to add a background image, create a new div and apply the fade effect.

Check out this fiddle I made for reference: https://jsfiddle.net/bx0dt60a/

Here's a snippet of the JS code:

$('#fadeOut').click(function(){
$('#background').fadeOut(500);
});

$('#fadeIn').click(function(){
$('#background').fadeIn(500);
});

.container {
  width: 500px;
  height: 500px;
  background-color: red;
}

.background {
  width: 100%;
  height: 100%;
  background-image: url('http://www.menucool.com/slider/jsImgSlider/images/image-slider-2.jpg');
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id"container" class="container">
  <div id="background" class="background"></div>
</div>

<div id="fadeOut">
  fade out
</div>
<div id="fadeIn">
  fade in
</div>
