The main difference between an HTML <textarea></textarea> and an <input type="text"> is that the textarea allows for multiline text input, while the input text field only supports a single line. This fundamental distinction affects how each should be used in practice.

When to Use <input type="text">

Use this when you expect users to enter short, single-line responses. It's ideal for things like names, email addresses, search queries, or any kind of brief user input.

• You can set a maxlength attribute to limit character count
• Browsers often provide autocomplete suggestions based on previous entries
• Easier to style consistently across browsers

For example, a login form usually has two text inputs: one for username and one for password (though the password input uses type="password" instead).

<input type="text" name="username" placeholder="Enter your username">

This keeps things simple and focused, since expecting someone to paste a paragraph into a username field wouldn't make sense.

When to Use <textarea>

Go with <textarea> when you need users to write longer, more expressive content. Think comment boxes, feedback forms, or message fields where multiple lines are expected.

• Supports line breaks and paragraphs naturally
• Can be resized by default (or restricted via CSS)
• Better suited for large amounts of text input

A common use case might be a contact form where visitors can describe their inquiry:

<textarea name="message" rows="5" cols="30"></textarea>

Here, forcing everything into one line would be inconvenient and possibly lead to less detailed messages from users.

Styling and Behavior Considerations

Both elements can be styled with CSS, but there are some quirks to keep in mind:

• Textareas can have rows and cols attributes, which define visible size (but you're better off using CSS for layout control)
• Input fields respect the size attribute to visually adjust width
• Both support placeholders, required fields, and other standard form features

One thing to note: if you want a textarea that doesn’t allow resizing, you can add this CSS:

textarea {
  resize: none;
}

Or restrict it vertically only:

resize: vertical;

That helps maintain design consistency without frustrating users.

Depending on what kind of data you’re collecting, choosing between <input type="text"> and <textarea></textarea> comes down to expected input length and format. Keep it simple — use the right tool for the job, and users will thank you for it.
