Need to have a container change a background automatically?
I didn’t know you can not use transitions with background-image on a single container. It will give you lots of troubles on different browsers.
What you can do is use opacity transitions with multiple containers.
HTML
You can modify this to fit your needs. In my case I wanted the images to behave as background, under my content.

1 2 3 4 5 6 7 8 9 |
<div class="container"> <div class="content">We could have anything here</div> <div class="slide show" style="background-image: url('image-1.jpg');"></div> <div class="slide" style="background-image: url('image-2.jpg');"></div> <div class="slide" style="background-image: url('image-3.jpg');"></div> </div> |
SCSS
The basic CSS below. In my demo I’ve added extra CSS to position another container inside it. So I can have the slides as background under the content.

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 |
.container { width: 100%; height: 500px; position: relative; .slide { z-index: 1; position: absolute; width: 100%; top: 0; left: 0; height: 100%; transition: opacity 1s ease-in-out; background-position: center center; background-repeat: no-repeat; background-size: cover; opacity: 0; &.show { opacity: 1; } } } |
JavaScript
We’ll use jQuery for ease of use.

function cycleBackgrounds() { var index = 0; $imageEls = $('.container .slide'); // Get the images to be cycled. setInterval(function () { // Get the next index. If at end, restart to the beginning. index = index + 1 < $imageEls.length ? index + 1 : 0; // Show the next $imageEls.eq(index).addClass('show'); // Hide the previous $imageEls.eq(index - 1).removeClass('show'); }, 2000); }; // Document Ready. $(function () { cycleBackgrounds(); }); |

I added your code to my site exactly as you have it yet it’s not working, only the 1st image loads.

Unfortunately the code is not as easy as plug and play. Some tweaking might be needed.
Impossible for me to predict every case 🙂

Can u tell me about path in html……I mean how to set path.
Rick
I’m not sure what to you mean. Path depends on where you have your images.

I could get the slideshow to work but, the text also shows as part of the slideshow. Like, it has its own slide. Do you have any idea how fix this? Thanks in advance.
Rick
Super hard to say without seeing the code.
Werner
Works great, thank you.
Only, the first slide stays longer than all other slides. I guess the JS would need some change. But I don’t know much of it.

This works wonderfully! Thanks! I have one question. I am trying to add Forward and Backwards buttons for clicking through the background images. I’m not too good with Jquery, but here is the updated code that I’ve come up with:
It somewhat works, but not quite the way it should:
1) The timer doesn’t start over when the button is clicked.
2) The button clicks only work one time until the next slide is displayed.
3) If the forward button is clicked when the last image is currently displayed, a blank background will show.
Any help would be much appreciated!
Thanks,
Shayne

Nevermind. I figured it out. It might not be the most elegant way, but it works 🙂
Rick
It’s not bad, perhaps you could move into variables the class. In case it ever changes. Also move from ID to CLASS for the forward and backwards selectors.
Best regards
