A simple JavaScript + HTML + CSS based library to rotate text that's encapsulated with-in an HTML element.

Check out the demo here.

Also a documentation page with demo is here: https://compumaster.github.io/html-text-rotator

To use the html-text-rotator library, follow these steps:

1. Include the necessary files in your HTML document. You will need to include the script.js file, the styles.css file.
2. For the text you want to rotate, replace the text with a span, other html elements are okay too. <span id="food" class="text-rotator" data-options="beans|a large cucumber salad|pea|avocado toast|beets|potatoes" data-random="true" data-mode="fadeoutandreplace" data-rand-max-sleep="500" data-baseline-sleep="2000"></span>

• data-options is required, all options needs to be separated with |
• data-random is optional, default is false, if true then randomly sorts the data-options
• data-mode is optional, default is "fadeoutandreplace". Other option is "fadeoutthenreplace", it changes how the transition is animated.
• data-rand-max-sleep is optional. Default is 0. If set, randomly waits maximum duration in ms specified before rotating each text. This duration is added to duration specified in data-baseline-sleep
• data-baseline-sleep is optional. Default is 2000. If set always waits before rotating each text. This duration is added to random duration specified in data-rand-max-sleep

If you want to make the animation's speed of transition slower (not the actual wait between each text rotation). In CSS, we have the transition timing of 0.5 seconds. This should match the setTimeout duration specified in RotateText1 and RotateText2 methods. I didn't parameterize this because it involves changing CSS too, and I don't think there would be much demand for this.

.text-rotator {
  white-space: nowrap;
  opacity: 1;
  /* the transition durations should match the animation durations */
  transition: opacity 0.5s ease, width 0.5s ease-in-out;
  display: inline-block;
}

.text-rotator.fade-out {
  opacity: 0;
}

------------

setTimeout(() => {
  this.element.textContent = this.elementOptions[this.elementIndex];
  this.element.classList.remove("fade-out");
}, 500);

Thanks Quba for making me implement this. It was fun.
