How to Create an Infinitely Looping Fading Animation for \'Loading\' Text with CSS?

Creating a CSS-only Animation Loop for Fading "Loading" Text

In this tutorial, we aim to create a CSS animation that simulates a fading "Loading" text without using JavaScript.

Problem Statement:

You have created a basic CSS animation using keyframes, but it's not looping and fading in and out infinitely.

Solution:

To create a looping animation, add the animation-iteration-count and animation-direction properties. animation-iteration-count specifies the number of times the animation should repeat, while animation-direction determines whether the animation should play forwards or reverse.

Next, you must include browser-specific prefixes for better compatibility.

The modified code below incorporates these changes:

<code class="css">@keyframes flickerAnimation {
  0%   { opacity: 1; }
  50%  { opacity: 0; }
  100% { opacity: 1; }
}

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

@-moz-keyframes flickerAnimation {
  0%   { opacity: 1; }
  50%  { opacity: 0; }
  100% { opacity: 1; }
}

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

.animate-flicker {
  -webkit-animation: flickerAnimation 1s infinite normal;
  -moz-animation: flickerAnimation 1s infinite normal;
  -o-animation: flickerAnimation 1s infinite normal;
  animation: flickerAnimation 1s infinite normal;
}</code>

Usage:

Apply the animate-flicker class to the element where you want the "Loading" text to appear:

<code class="html"><div class="animate-flicker">Loading...</div></code>

This will create an infinite animation that fades the text in and out continuously.
