Text Area in HTML
HTML, or HyperText Markup Language, is the backbone of web development, providing the structure and content for websites. Within the realm of HTML, various elements serve different purposes, and one such element that plays a crucial role in user interaction is the <textarea> element. The <textarea> element is used to create a multi-line text input field, allowing users to enter and edit larger amounts of text. In this article, we will explore the syntax, attributes, and practical applications of the <textarea> element.
Syntax:
The basic syntax for the <textarea> element is straightforward:
Code:
<textarea rows="4" cols="50">
Enter your text here...
</textarea>
Let's break down the key components:
- <textarea>: This is the opening tag of the element.
- rows="4": This attribute determines the number of visible rows for the textarea.
- cols="50": This attribute specifies the number of visible columns for the textarea.
- Enter your text here...: This is the default content or placeholder text within the textarea.
- </textarea>: This is the closing tag of the element.
Attributes:
1. Rows and Columns:
The rows and cols attributes allow developers to define the visible size of the textarea. These attributes help create a specific structure for the input field, giving users a visual indication of the expected length and width of their input.
Code:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>JTP</title>
<style>
body {
font-family: 'Arial', sans-serif;
background-color: #f2f2f2;
padding: 20px;
}
textarea {
width: 100%;
padding: 10px;
margin: 10px 0;
box-sizing: border-box;
border: 1px solid #ccc;
border-radius: 5px;
font-size: 14px;
resize: vertical;
/* Allows vertical resizing */
}
</style>
</head>
<body>
<textarea rows="4" cols="50" placeholder="Enter your text here..."></textarea>
</body>
</html>
Output:
2. Placeholder:
The placeholder attribute allows developers to provide a hint or example text that appears in the textarea before the user enters any content. This can be particularly useful for guiding users through what type of information is expected.
Code:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<style>
body {
font-family: 'Arial', sans-serif;
background-color: #f4f4f4;
margin: 0;
padding: 0;
display: flex;
justify-content: center;
align-items: center;
height: 100vh;
}
textarea {
width: 100%;
padding: 10px;
box-sizing: border-box;
border: 1px solid #ccc;
border-radius: 5px;
font-size: 14px;
resize: vertical;
/* Allows vertical resizing */
}
::placeholder {
color: #999;
/* Placeholder text color */
}
</style>
</head>
<body>
<textarea rows="4" cols="50" placeholder="Enter your text here..."></textarea>
</body>
</html>
Output:
3. Disabled:
The disabled attribute makes the textarea uneditable. This is useful when you want to display information to the user but want them to keep the content the same.
Code:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>JTP</title>
<style>
body {
font-family: 'Arial', sans-serif;
