How Do I Create a Seamless Looping Animation with CSS3?

Seamlessly Looping CSS3 Animations

Problem:

You want an uninterrupted animation that seamlessly transitions from the last frame to the first, creating a continuous loop effect.

Solution:

1. Use the animation-iteration-count Property:

Add the following property to your keyframes:

animation-iteration-count: infinite;

This property specifies the number of times the animation will repeat. By setting it to infinite, the animation will loop indefinitely.

2. Revised CSS Code:

Here is the updated CSS code:

@keyframes fadeinphoto {
    0% { opacity: 0; }
    50% { opacity: 1; }
    100% { opacity: 0; }
    animation-iteration-count: infinite;
}

@-moz-keyframes fadeinphoto {
    0% { opacity: 0; }
    50% { opacity: 1; }
    A100% { opacity: 0; }
    animation-iteration-count: infinite;
}

@-webkit-keyframes fadeinphoto {
    0% { opacity: 0; }
    50% { opacity: 1; }
    100% { opacity: 0; }
    animation-iteration-count: infinite;
}

@-o-keyframes fadeinphoto {
    0% { opacity: 0; }
    50% { opacity: 1; }
    100% { opacity: 0; }
    animation-iteration-count: infinite;
}

Explanation:

By specifying animation-iteration-count: infinite, each photo will fade in, remain visible for a period of time, and then fade out only to transition smoothly back to the first photo, creating an endless loop.

Note:

Ensure that your animation is designed such that the opacity transitions from 1 to 0 (or vice versa) for the loop to work seamlessly.
