Let's consider a scenario where we have an input element with the following text:
<input type="text" value="Lucas">
Is there a way to emphasize the "L" in the value as Bold, similar to Lucas?
We are familiar with how this can be achieved using <span> and <div> elements:
<span><strong>L</strong>ucas</span>
But can we apply such styling to an <input> element? And if so, would the value of the input still display the same regardless of the formatting changes?
If you're looking to achieve a specific behavior with an <input> or <textarea>, using them alone won't suffice. One approach is to hide the actual element and create a facade that copies the values from it, displaying them as raw HTML in a <div>:
<!-- An element to handle your content input triggering a function -->
<input id='input' onkeyup='updateOutput(value);' />
<hr />
<!-- The output display element -->
<div id='output'></div>
<script>
// Function to map the input content and display it in the "output" element
function updateOutput(html){
document.getElementById('output').innerHTML = html;
}
</script>
You can view an example of this concept here as shown below:

Alternatively, consider using a Javascript-based HTML editor such as TinyMCE or CKEditor for a more robust solution.
