Master HTML Textarea: Complete Guide to Integrate It Successfully

The element of textarea in HTML is an essential tool when it comes to collecting opinions, comments, or any type of extensive text from users on a web page. This component is vital in registration forms, comment sections, and many other situations where multiline text entry is required by the user.

A textarea is a flexible text area that can adapt to content of different sizes. Below, we'll explore its features and how you can implement it effectively, with practical examples that you can apply in your own projects.

What is a Textarea and What is it for?

Before going into details, let's briefly define what a textarea. In HTML, a textarea is a form control that allows text entry on multiple lines. Unlike a "text" type input that accepts a single line, the textarea It is ideal for longer texts.

Some of the most common uses of a textarea include:

• Contact forms where users can write a message.
• Comment systems on blogs or forums.
• Interfaces for code or text editing (such as an online text editor).
• Surveys where broad and detailed answers are needed.

Characteristics of the Textarea Element in HTML

The element textarea It is characterized by its simplicity and highly configurable nature. These are some basic properties that can be adjusted:

• rows y cols: Control the size of the textarea in terms of height and width based on the number of lines and columns.
• placeholder: It is an example text that is displayed in the text area until the user starts typing.
• name: Important to identify the data received on the server when processing a form.
• maxlength: Limits the maximum number of characters allowed.
• readonly y disabled: Set the textarea as read-only or disabled, respectively.
• autofocus: It serves so that the textarea Automatically receive focus when the page loads.

Additionally, JavaScript events can be used to add interactivity, such as limiting the number of characters in real time or formatting entered text.

Textarea Implementation Examples

Let's look at some examples on how to integrate the element textarea in your web forms.

Basic Textarea

To add a textarea simple in your HTML, you basically need the following code:

This example creates a textarea where users can write comments of up to 5 visible lines and with an initial width of 30 characters.

Textarea with Character Restrictions

To limit the number of characters a user can enter, we use the property maxlength.

Here, users have a restriction similar to that of a tweet, with a maximum of 280 characters.

Textarea with Javascript to Count Characters

We can use Javascript to display a counter for remaining characters, improving user interaction with the text area.

<textarea id="mensaje" name="mensaje" rows="4" cols="50" maxlength="500" placeholder="Your message here..."></textarea>
<div id="contador">500 characters remaining</div>

<script>
  const textarea = document.getElementById(&#039;mensaje&#039;);
  const contador = document.getElementById(&#039;contador&#039;);

  textarea.addEventListener(&#039;input&#039;, function() {
    const caracteresRestantes = 500 - this.value.length;
    contador.textContent = `${caracteresRestantes} caracteres restantes`;
  });
</script>

In this example, every time the user writes or deletes something, the counter is updated instantly.

Adaptive Textarea with CSS

We can use CSS to make the textarea be more visually attractive and adapt better to different devices.

textarea {
    width: 100%;
    max-width: 500px;
    min-height: 100px;
    padding: 10px;
    box-sizing: border-box;
  }

With these styles, the textarea It now resizes responsively based on the width of the screen, ensuring it is always visible and readable on mobile devices.

Textarea with AutoComplete and Autofocus

In some cases, we want the focus to be immediately on the textarea on page load and suggest autocompletes based on the user's previous history on your website.

With autocomplete="on" y autofocus, we achieve this behavior.

Incorporating Textarea into a Full Form

Finally, an example of how the textarea can be incorporated into a longer form with other controls.

Name: E-mail: Message: 

This form is submitted to the specified URL using the method post and includes a text area for the user's message.
