The HTML <label> tag is an important element used in form controls to associate labels with form input elements such as text fields, radio buttons, checkboxes, and more. The primary purpose of the <label> tag is to improve the accessibility of forms by linking descriptive text to the form controls, making it easier for users, including those using screen readers, to understand the purpose of each input field.
Syntax of the <label> Tag
<label for="inputID">Label Text</label>
- for: This attribute associates the <label> with an input element. The value of the for attribute should be the same as the id attribute of the corresponding form element.
- Label Text: This is the descriptive text that helps users understand the function of the associated input field.
Alternatively, you can wrap the input element inside the <label> tag:
<label>Label Text <input type="text" name="example"></label>
In this case, there is no need to use the for attribute, as the label automatically applies to the enclosed input element.
Attributes of the <label> Tag
The <label> tag supports the following attributes:
| Attribute | Description |
|---|---|
| for | Associates the label with an input element by matching the id of the input. |
| global attributes | Supports global attributes like class, id, style, and more for styling or identification purposes. |
- for: The for attribute links the label to a specific form element by matching its id. This is especially important for improving accessibility, as screen readers use this association to describe form fields to users.
The global attributes, such as class and id, can be used to style the <label> tag or reference it in JavaScript.
Examples of HTML <label> Tag
Example 1: Using the for Attribute to Associate a Label with an Input Field.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Label Example</title>
</head>
<body>
<form>
<label for="name">Full Name:</label>
<input type="text" id="name" name="name">
</form>
</body>
</html>
In this example, the label "Full Name" is associated with the input field through the for ="name" attribute, matching the id ="name" of the input. This makes it easy for users to click on the label to focus the input field.
Example 2: Wrapping the Input Element Inside the <label> Tag
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Label Without "for" Attribute</title>
</head>
<body>
<form>
<label>Username: <input type="text" name="username"></label>
</form>
</body>
</html>
Here, the input field is nested inside the tag. This is another method of associating the label with the input element, eliminating the need for the for attribute.
