The <textarea> HTML element is used to create a multi-line text input field in a form. Unlike the <input> element with type="text", which is typically used for single-line input, the <textarea> element allows users to enter larger blocks of text, such as comments, messages, or descriptions. It is a versatile form element that can be customized in size and appearance.

The <textarea> element is a block-level element that can contain text as its initial value, which is displayed to the user when the page loads. It can be styled and resized according to the needs of the application. Here is an example of how the <textarea> tag can be used:
<label for="comments">Comments:</label>
<textarea id="comments" name="comments" rows="4" cols="50">
