How can CSS be used to remove default margins from form elements in PHP?

To remove default margins from form elements in PHP, you can use CSS to target the form elements and set their margins to 0. This can be achieved by adding a style attribute to the form elements or by including a separate CSS file in your PHP code. 

<!DOCTYPE html>
<html>
<head>
    <style>
        form {
            margin: 0;
        }
        input {
            margin: 0;
        }
        select {
            margin: 0;
        }
        /* Add more styles for other form elements as needed */
    </style>
</head>
<body>
    <form action="submit.php">
        <input type="text" name="username" placeholder="Username">
        <input type="password" name="password" placeholder="Password">
        <select name="gender">
            <option value="male">Male</option>
            <option value="female">Female</option>
        </select>
        <button type="submit">Submit</button>
    </form>
</body>
</html>
