How Can I Embed and Render HTML Tags Within a Text Area in My Web Application?

Embedding HTML in a Text Area

When working with HTML forms, it can be advantageous to embed certain HTML tags within the text area to enhance the user experience. However, conventional text areas treat their content solely as text, making it challenging to render HTML tags effectively.

Seeking a Solution

To overcome this limitation, consider leveraging a content editable div instead of a text area. Unlike text areas, content editable divs allow users to enter and edit HTML content directly. This enables the rendering of HTML tags, such as **, , , and .

Implementation with HTML and CSS

To incorporate a content editable div, use the following HTML code:

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

To style the div appropriately, add the following CSS:

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

strong {
  font-weight: bold;
}

Example Usage

Consider the following example with a content editable div:

<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>

In this code, the tag is used to bold the word "linebreak" and a span tag with a lightgreen color is used to change the color of the word "Great."

Adopting this approach provides a straightforward and effective way to render HTML tags within your web application without relying on external libraries or plugins.
