Along with input fields, labels are often used, which are represented by the label element . Labels create an annotation or heading for an input field, indicate what the field is for.
To associate with an input field, the label has a for attribute that points to the id of the input field:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Label In HTML5</title>
</head>
<body>
<form>
<div class="form-group" style="margin-bottom: 15px;">
<label for="login">Login: </label>
<input type="text" autofocus id="login" name="login" />
</div>
<div class="form-group" style="margin-bottom: 15px;">
<label for="password">Password: </label>
<input type="password" id="password" name="password" />
</div>
<div class="form-group">
<button type="submit">Submit</button>
</div>
</form>
</body>
</html>
So, the text box here has an attribute id=”login”. Therefore, an attribute is set on the associated label for=”login”. Clicking on this label allows you to move the focus to the text field for entering the login:

Actually, this is where the role of labels ends. We can also set autofocus by default to any input field. The autofocus attribute is used for this:
<form>
<div class="form-group">
<label for="login">Login: </label>
<input type="text" autofocus id="login" name="login" />
</div>
<div class="form-group">
<label for="password">Password: </label>
<input type="password" id="password" name="password" />
</div>
<div class="form-group">
<button type="submit">Submit</button>
</div>
</form>
Here, when the page starts, focus immediately goes to the text field.
