Problem

Aren't typewriter effects cool? They can be used to create a sense of suspense or to make your content more engaging. You can easily create a typewriter effect using CSS variables and just a sprinkle of JavaScript.
You'll first need to define two animations, typing to animate the characters and blink to animate the caret. You can use the ::after pseudo-element to add the caret to the container element. Then, you can use JavaScript to set the text for the inner element and set the --characters variable containing the character count. This variable is used to animate the text.
Finally, use white-space: nowrap and overflow: hidden to make content invisible as necessary.

Solution

<div class="typewriter-effect">
  <div class="text" id="typewriter-text"></div>
</div>
