Display HTML in a TextArea Without External Tools

Rendering HTML tags within a textarea presents a challenge due to textareas' inherent text-only nature. To overcome this limitation, consider employing a content editable div, which effectively allows for the manipulation of HTML content.

Implementing Content Editable Divs

Implementing a content editable div is straightforward:

<div contenteditable="true"></div>

This div grants you full control over its content, including the inclusion of HTML tags for formatting and structure.

Example

To illustrate the functionality of a content editable div, refer to this example:

HTML

<div contenteditable="true">
    This is the first line.<br>
    See, how the text fits here, also if<br>
    there is a <strong>linebreak</strong> at the end?<br>
    It works nicely.<br>
    <br><span>

CSS

div.editable {
    width: 300px;
    height: 200px;
    border: 1px solid #ccc;
    padding: 5px;
}

strong {
    font-weight: bold;
}

This example demonstrates how content can be dynamically modified, including adding HTML tags for emphasis (), color changes, and line breaks.
