How can I create a continuous looping animation in CSS3 where the first image seamlessly fades in as the last image fades out?

Creating a Seamless Looping Animation in CSS3

Problem:

You want to create an infinite animation sequence where the first image fades in when the last image fades out.

Provided Code:

The provided HTML and CSS code establishes a series of five images that fade in sequentially, but upon reaching the last image, the page reloads.

Solution Using animation-iteration-count:

To achieve an infinite loop without reloading the page, add the following property to the animation rules:

animation-iteration-count: infinite;

This property specifies the number of times the animation should repeat. By setting it to infinite, you ensure that the animation runs indefinitely.

Updated CSS:

/* Animation Keyframes*/
@keyframes fadeinphoto {
    0% { opacity: 0; }
    50% { opacity: 1; }
    100% { opacity: 0; }
}

@-moz-keyframes fadeinphoto {
    0% { opacity: 0; }
    50% { opacity: 1; }
    A100% { opacity: 0; }
}

@-webkit-keyframes fadeinphoto {
    0% { opacity: 0; }
    50% { opacity: 1; }
    100% { opacity: 0; }
}

@-o-keyframes fadeinphoto {
    0% { opacity: 0; }
    50% { opacity: 1; }
    100% { opacity: 0; }
}

.photo1 {
    opacity: 0;
    animation: fadeinphoto 7s 1 infinite;
    -moz-animation: fadeinphoto 7s 1 infinite;
    -webkit-animation: fadeinphoto 7s 1 infinite;
    -o-animation: fadeinphoto 7s 1 infinite;
}

.photo2 {
    opacity: 0;
    animation: fadeinphoto 7s 5s infinite;
    -moz-animation: fadeinphoto 7s 5s infinite;
    -webkit-animation: fadeinphoto 7s 5s infinite;
    -o-animation: fadeinphoto 7s 5s infinite;
}

.photo3 {
    opacity: 0;
    animation: fadeinphoto 7s 10s infinite;
    -moz-animation: fadeinphoto 7s 10s infinite;
    -webkit-animation: fadeinphoto 7s 10s infinite;
    -o-animation: fadeinphoto 7s 10s infinite;
}

.photo4 {
    opacity: 0;
    animation: fadeinphoto 7s 15s infinite;
    -moz-animation: fadeinphoto 7s 15s infinite;
    -webkit-animation: fadeinphoto 7s 15s infinite;
    -o-animation: fadeinphoto 7s 15s infinite;
}

.photo5 {
    opacity: 0;
    animation: fadeinphoto 7s 20s infinite;
    -moz-animation: fadeinphoto 7s 20s infinite;
    -webkit-animation: fadeinphoto 7s 20s infinite;
    -o-animation: fadeinphoto 7s 20s infinite;
}

With this modification, the animation sequence will now loop infinitely, ensuring a seamless transition from the last image to the first.
