I have a simple full screen background image as shown below:
body {
/* The background image used */
background-image: url("../images/bg-one.jpg");
/* Full height */
height: 100vh;
width: 100vw;
/* Hide scroll */
overflow-x: hidden;
overflow-y: hidden;
/* Center and scale the background image nicely */
background-position: center;
background-repeat: no-repeat;
background-size: cover;
}
I would like to know how I can make the background image change every 5 seconds with a fade in/out transition. Sorry if this seems like a newbie question but I'm just starting out learning Js/Jquery.
My second question would be is it possible to do this using pure CSS3 or would js/jquery work better?
Many thanks, Aidan
I have created a test case for you using jquery: https://codebrace.com/editor/afec3e661
With pure js you may replace jquery with document.body.style.backgroundImage = "url('" + a[i++] + "')";
Test case for background change with fadein/out effect: https://codebrace.com/editor/afef034d6
You can't make fade-in fade-out
animation on background-image
, because this atribute cannot be animated. Instead of it, you can make 2 fixed elements which are positioned over each other.
You can't make timeout/interval in plain CSS, you'll have to use JS. I've used setInterval
function which is switching .active
state of two elements, class .active
adds to element opacity
with transition
- example is here: https://jsfiddle.net/2cxmeq7p/
